Narrator: Welcome to the Dusty Jobs Podcast from Imperial Systems. Industry knowledge to make your job easier and safer.

Donovan: Thanks again for joining us and welcome to another Dusty Jobs podcast. We’re excited. We have a couple guests today. We’ve got Russ Ryland, our head service tech, and Jeremiah Wann, the owner of our company. How are you doing Jeremiah?

Jeremiah: I’m doing well. Thanks.

Donovan: Do you have anything you want to say about this podcast?

Jeremiah: We were just talking earlier that this is our first multi-person podcast. Hopefully it will be a little bit more enjoyable and relaxing. When I do it I’m usually uptight and super nervous. I’m going for fun today. We’ll see what happens.

Donovan: More than just me talking too. Russ how are you feeling today?

Russ: Doing good.

Donovan: You doing good? I know Russ would prefer climbing in a machine and fixing it, probably, than being in the office. That’s his M.O. He’s always out in the field, always traveling and helping people out. We really appreciate that here. The wealth of knowledge, the wealth of…well, I’ll stop talking about it. Why don’t you tell me about yourself Russ. How long have you been doing this type of work?

Russ: Well, I’ve been working for Imperial Systems for seventeen and half years now. I’ve kind of held many positions throughout the company and just worked up to running our service department and taking care of our customers.

Donovan: Now, you’ve got to tell this story, because I think it’s great. Tell us how you got started with Imperial Systems.

Russ: Well, I was going to school at night for mechanical engineering and technology and working at CCX at the time. They made some changes that was going to interfere with my school schedule. So I called Jeremiah up on my lunch break and told him that he’s going to hire me and I’m going to start in two weeks.

Jeremiah: That’s his version of it.

Donovan: Let’s hear your version of how this came on.

Jeremiah: I don’t remember the phone call. I don’t remember that. I just remember sitting around a campfire…

Donovan: Did he just show up one day?

Jeremiah: Kind of. No, I just remember that that was in 2002 maybe…

Russ: 2003

Jeremiah: You have to put it in context. I had a third bedroom office in my house. No customers. I couldn’t pay my own mortgage basically. We had, I think, about two guys in the shop, including myself. So I’d go into the midnight shift and work after I’d get done selling all day. Russ and I were just hanging out all the time. We just did everything together. So we were at my cousin’s bonfire one night, which is a western Pennsylvania thing if you’re not familiar with that. It’s pretty common around here. At our age it was common. I don’t do it too much anymore. One night we were just kind of sitting around the bonfire and he said, “I quit my job. When am I starting?”

And I’m like, “What?”

So I said, “Of course you’re starting but I don’t know how I’m going to pay you.” Real quick on that though, he came to work for me a few months later, and we laid him off and pretty much everyone else because we just didn’t have any work at the moment. So I was over at his house and his mom comes out and says something about, “Oh, Russ made more money on unemployment than he did working for you.” Thanks Ms. Ryland. That’s my version of it.

Donovan: Well, I know this from being able to interact with Russ and having him close by and being able to pick up the phone. I am glad he came back after unemployment and stuck it out because man he’s just such a valuable resource we have here with his knowledge. Russ you’ve been not only working on our collectors but you’ve been in – how many different types of collectors do you think you’ve worked on over the years?

Russ: Just about every brand you can imagine. I mean, I’ve been in some from the 50s. So, yeah, about every brand you can imagine, every style of collector out there at some point in time I’ve dealt with. Whether we’re just trying to help a customer repair what they have existing or just evaluate and see whether it’s even practical to fix on some of them.

Donovan: I think some people don’t know that. When they think of Imperial Systems or they think of what we do here they think we just build dust collectors. We’re more than that, man. We do full system work, full system design. Even if you get that machine out there and you need someone to come and help you turn it on and start it up. Russ is the guy that would be there, or Connor. We have a team of people who can go out and help do that. That’s why we have him on today to just help bring more knowledge to that that we’re not just building collectors and putting them out there. We’re full service and full everything here. The other thing is we’re going to give a little free advice today too. We’re going to give a little free knowledge. We’re going to let Russ handle maybe a few of those phone calls we get 100 times and just put it out here now so people can listen. So, we’re going to dive into a couple issues. Issue number one, Russ: fire. A lot of people have dust collector fires. What do you see? When you normally show up at a dust collector fire, what is the main cause of that that you see a lot of the time?

Russ: Sometimes it’s hard to pinpoint. Usually it’s some type of spark that got in the system or something hot depending on the source and the process that the plant is under. In wood applications it can be sanders. If the belt on a sander breaks and is on fire, I’ve seen that. In the metal cutting industries its usually sparks from plasma cutting or grinding. Those are usually the biggest culprits on those. Heck I saw one blast machine where they fed wood into it from a pallet.

Jeremiah: I was at that one numerous times.

Donovan: They just put the whole thing in there?

Russ: The whole pallet with the parts and it vaporized the pallet basically.

Donovan: I can imagine. I can imagine. So, once you arrive on the scene and there’s been a fire, what’s the first thing you’re looking at? What do you evaluate? Obviously by the time you arrive there the fire is out, the collector has cooled down. When you show up what are you looking at? What are the things you’re trying to assess on that machine to see where the damage is? Where do you see most of the damage in those situations?

Russ: The first thing you see is the paint job on the collector. Did it get hot enough to melt all the paint off? If it melted all the paint off, that’s telling you that the seals between all the joints could have possibly melted away. So that’s first. The overall condition when you first see the collector. If the paint is fairly intact then a lot of the gasketing probably survived. Then you just go from there to where you start looking at the tube sheet to see if the filters can seal against it still.

Donovan: You’re saying in a high heat situation you get warping? Is that what you see?

Russ: You can. You can have some warping in the tube sheet from immense heat. It all depends on how intense the fire was. 

Donovan: A mild fire might just need new filters but at some point you might need a whole new system.

Jeremiah: Yeah, the lift mechanisms, whatever holds the filter in might warp. They might be shot. The door might be warped. The CMAXX has a very heavy door but its big so if it warps its either going to need to be adjusted or replaced depending on how hot the fire is, for sure.

Donovan: And I know this: The number one way to save your collector is just not to have a fire in it, right?

Russ: Yup.

Donovan: So, Russ has been here for a lot of it, and the other thing we didn’t talk about is how Russ helps with our R&D too. He really helps develop products. I think you and Jeremiah both were the ones who came up with our Spark Trap. You guys kind of worked on that together.

Jeremiah: I think so.

Russ: Yeah.

Jeremiah: Before we get into that though I want to go back to the fires. One of the important things that people don’t realize when they have a fire is that nobody is ever prepared for it. Somebody from the office looks out and there’s smoke pouring out of the dust collector or there’s smoke coming back in the plant or from the return air because a filters on fire. So what do you do? We’ve seen cases where people have gone up there and literally opened up the door and tried to put it out. These can be metal fires that you can’t put water on. You might have to put some type of an agent on there or CO2 or something like that to get it knocked out. So you should not try to handle that fire on your own. The best and the safest thing you can do is call the fire department. Have the fire department come out and deal with it. Quite frankly, you should have a site assessment done before. So if you’re putting in a dust collector, call your fire department and let them know you’re putting one in. Go over the plans with them. Explain to them what you’re doing, what the dust type is, what the sprinkler system looks like in the collector. Then come up with a protocol because you’ll never be prepared for it.

I’ll share a funny story with you. This is going back eight, nine years. I walked out into the plant and we had a couple guys up on a man lift, a scissor lift welding on there. The sparks had gotten down, and when they did there were some rags laying on the bottom of the man lift. So all I saw was a fire on the bottom of the man lift and I saw two guys up on the man lift. I was like, “Hey!” So, they saw the fire and they pointed to the fire extinguisher and I grabbed it. You would think – I consider myself fairly intelligent. I can kind of take care of myself.

Donovan: You’ve had a good amount of life experience.

Jeremiah: I’ve had a decent life experience. I couldn’t figure out how to get that fire extinguisher to work for the life of me. I just was in a panic mode. I wasn’t prepared for it. So it’s like a dust collector is the same way only a lot more severe.

Donovan: And complicated.

Jeremiah: And complicated. You open the door and now you’re introducing oxygen. Now you’re standing there. These people have families they have to go home to at night. So you want to make sure that they’re taken care of.

Donovan: Normally the door is up high. You might be on a ladder.

Jeremiah: They’re trapped on a catwalk. You don’t want to do that. You get with your AHJ, or authority having jurisdiction, and your fire department. Just run through everything with them. It’s better for us too because it’s less likely that the thing is going to burn so bad to where it warps or damages things. When we get there Russ can literally put new gaskets on and put some filters in and its fixed and everybody is safe.

Donovan: Save everybody money. Save everybody downtime. Save everybody’s life is what we’re looking for.

Jeremiah: Or you can take it a step further and before you put the dust collector in make sure you partner with a good company, whether its us or somebody else, that knows about combustible dust and fire hazards because you can put a lot of devices in. You can put CO2 systems in. You can put wet systems in. You can put dry systems in. Theres a lot of things you can do. So just make sure, I’d just tell the listeners or the viewers, to make sure you’re paired with the right company when you’re putting a dust collector in. I got off track. I just wanted to circle back to that.

Donovan: No, there’s no off track here. One of the ways you guys have developed to prevent fires was our Spark Trap. We’ve seen that effective in a lot – not just our collector, but a lot of collectors. It’s really great. It’s a good piece of equipment. If you’re listening now and you’ve had a fire or on your plasma table or on your laser table that’s a real simple, low cost, easy to install piece that can help prevent that.

Jeremiah: Grinding, blasting, torch, plasma, laser, anything with metal…

Russ: Yeah, basically any of these processes that can create a fine dust that could have a spark in the process.

Jeremiah: It has to have some mass to it too, and that’s the key. We get a lot of calls. We got a call from Disney World. They wanted to put one on their outdoor smoker. It was a big smoker. It was like an eight inch diameter…we said that if it doesn’t have some mass to it like metal dust, it’s an impingement type tortuous device is essentially what it is. That ember has a shield of fire around it. It has to actually hit something and knock itself out. Think about if you ever get grinding dust or if you’re welding and you get a bary, you know, and it gets on you. That’s a pretty heavy, molten piece of steel. It has enough mass to knock itself out. If you’re doing buffing for firearms, let’s say, and you have cotton and a rouge, burning embers of cotton. It won’t put that out. We’ve seen that before. People have misapplied them.

Donovan: Just call us. We’ll figure it out.

Jeremiah: We can do it.

Donovan: And if that’s not the solution we have other ones. I feel like we did a pretty good job on fire there.

Jeremiah: I think we did.

Donovan: Let’s move on. Let’s think here. Do you ever show up to a collector and it is just packed full of material? Do you ever have that experience Russ?

Jeremiah: Not our collectors. No.

Russ: I have seen a few out there. People don’t inspect their hopper that they’re filling, the drum underneath, or a screw conveyor plugs up or something like that. It just completely fills them to the top of the filters.

Donovan: You get that call. “Hey Russ. The collectors not…” and you open the door and its like someone stacked their locker, huh? Everything comes piling out.

Jeremiah: I have a funny story about that. I know Russ probably has a couple. When you’re either the salesman or the service guy and you pull up to a customer that you haven’t seen in a while or you’re just coming to say ‘hi’ the last thing you want to see is the customer at that dust collector trying to shovel it out, right? Because you know what that means? You’re getting dirty. You’re getting dirty. You’re going to spend the rest of the day helping them clean out that collector. Sometimes its not necessarily the design or the application. It’s just maybe an upset condition. There are things that can happen. I pulled up to one. It was a grain project. I pulled up to the collector. We had like eight or nine collectors on this job. I go up and there’s a guy going up with a skid steer to the dust collector, to the bottom of a baghouse, a BRF. So I’m kind of getting my hard hat out, kind of doing some stuff. All of a sudden I look back up and there’s no skid steer there anymore. Theres no guy. Theres no skid steer. He had opened the hatch on the grain bin and it completely just covered him. I know that’s kind of not funny in the industry because I know there’s been in grain silos some deaths and accidents. This one was on the ground and it could have been bad but it was just semi-funny because the guy was kind of completely covered with grain. I thought, “Oh, this is going to be a long day helping him get out.” It happens in our business, doesn’t it?

Russ: I remember when that one happened too.

Donovan: Russ, what about you? Do you have any experiences like that? Have you ever shown up to a collector and you’re like, “This is just…”

Russ: I had a plastic application where I showed up and they were having some issues with bridging over the airlock and it just completely filled the collector. Usually its lack of inspections and lack of checking the discharge device.

Donovan: Okay, so if we have somebody out there listening and they’re like, “Man, that happens to us all the time.” What are the things you could start to look for or notice. You’re saying an airlock. An airlock can bridge over. What would cause that? What would cause an airlock to bridge over?

Russ: One of the scenarios could be overfilling the discharge hopper underneath it and it allows it to back up through there. The simplest thing is just to check the discharge hopper more frequently. Other things could be a large object bridged across and settled on it. Run the collector without the airlocks running for an extended period of time and then turn them on. Did the dust form a cake above it? Those are some of the more common scenarios that we’ve run across.

Donovan: I can remember a couple pictures of this I’ve seen where you have the three sides of the hopper and they look all real nice and shiny and the other one looks like a steel drum from someone banging on it because it’s been bridging and that’s the only way.

Jeremiah: Yeah, you don’t want to see that. 

Donovan: That’s not the correct service plan.

Jeremiah: They need some help. You don’t want to see that when that’s your collector and you installed that. You don’t mind seeing that when you’re going on a sales call and they need to get a new collector. One thing to talk about with that is that there are people that have plug ups. One of the things that we see a lot and Russ and I have dealt with this numerous times is that you get it all cleaned out. You put the cover back on. You turn the airlock on. You get the fan running. They think they’re fine. Three hours later they call back and they’re plugged up again. “I just don’t understand it. What was it? I even found, in this case, I found a two by four that was covering the airlock or something. It doesn’t make sense”

Well what it is, is if you get a really bad plug and you’re up in between the filters. You’re just jammed up. It’s really, really important to go in there and either take the cartridges out or to take the bags out and literally take a stick and inspect down in there and make sure that all that’s cleared out. It’s a big job because the easier thing to do would be to just turn it back on and go, but you can cause yourself a lot of grief by not cleaning that out because if you get a football sized plug come down now you’re plugged again. 

Russ: It starts the chain reaction over again.

Jeremiah: I don’t know how many times we’ve gotten that call and they say, “We even found the board that plugged it. What caused it the second time?” 

“Well, did you clean it out good?”

“Yeah, we cleaned it out pretty good.”

“No, I mean did you clean it out really good?” That little ball of dust can be hanging up in there and cause a lot of problems.

Donovan: I know we’ve talked about this a lot here how our style of collector is a vertical style collector and we have a large door that makes it easy to access and to check all that. There are other collectors out there that could be having that problem because they have a horizontal style collector. That just allows more bridging in between those filters. 

Jeremiah: That’s interesting. I talked to one of our reps. He’s been with us several years now. He came from a leading competitor that makes a horizontal style cartridge. When we went and looked at our unit we opened the door up and you could see right down in the hopper. You know, you’ve got this big opening, about the size of this table, and you can look right down into the hopper. He said, “That is just amazing.”

I said, “What do you mean? I’m used to seeing this. What are you talking about?”

He said, “You can actually access the hopper if you need to.”

I still didn’t get it. “What do you mean?”

He said, “Well, the other ones were all these little holes that were all about this size. Theres no way to get down into that hopper to clean that out if it ever does bridge. I never dealt with that before so I never really noticed it. You’re absolutely right. Having that access is huge.

Donovan: At this table I am for sure the rookie, so this is a lot of stuff I’ve learned. I’ve learned a lot from you and from Russ. 

Jeremiah: You’re not a rookie anymore. You’re getting there. We’ve got to get him cleaning out a couple dust collectors. Or maybe you have?

Donovan: I’ve been on a couple with Russ.

Russ: We did take him on a filter change project on a collector right after it caught on fire.

Jeremiah: I’m still hearing about that. I still hear grumbling about that. I forgot.

Russ: That was a long day. That was a rough day. 

Donovan: It was a learning experience. We’ll leave it at that.

Russ: It was not our style of collector. The filers were ovals, bags.

Donovan: And that was a fire. 

Russ: It was from the aftermath of a fire.

Donovan: That makes it tough.

Jeremiah: Good learning experience.

Donovan: It burned the bags off. They fell down into the collector. It was a complicated process, but we were there to support the customer and help them get it done. Like you said, I’m not normally doing that. When we need service done we’re all on board here at Imperial.

Jeremiah: You’re so good at what you do now with your podcast that we would never do that to you again. 

Donovan: I’d be glad. I’d be glad to go with Russ and do the service. So, Russ, we talked about some of the issues that could happen, what happens with this bridging…material style, does that often lend to bridging? Different material styles?

Russ: Some materials are more prone to bridging. When you get into the longer, stringier type materials that cling together the material just naturally wants to cling to itself. Any kind of moisture presence can enhance that. Those types of materials you will see are more apt to bridge than some of the fine, loose dust. Anything that wants to clump is going to have the tendency to want to bridge.

Donovan: Maybe that’s another area people aren’t thinking to look for. If you’re getting moisture into your system somehow that’s causing you to bridge too, huh?

Russ: Yes, it can.

Donovan: That’s just a simple issue. Now, I don’t know if I’m describing this right but you were so tired of having to deal with this issue over and over again that you were kind of the spearhead of coming up with this Dust Level Sensor we have now, right?

Russ: Yeah with our drum kits, we kept coming across pretty frequently that people would fail to check the drums and empty the in a timely manner it can create backups into the collector. So we sat back and looked at some options and I kind of spearheaded it. We decided to do a drum dust level sensor. It’s a sensor that ultrasonically measures dust in the barrel. It can be used in any collector and any container where you can shoot down from the top. 

Donovan: Yeah, you just drill a hole in and it sends a sound wave down. Am I describing this well?

Russ: Yes, it sounds a sound wave. Whenever it bounces off the material within the specified range of the sensor it triggers the fault and sends an alert. We have outputs where we can just turn on a static light, turn on a horn or something, or shut the collector down depending on what level you want to go with that.

Donovan: Now I know there’s other styles of monitoring devices out there. One’s got a wire that kind of goes down in and can hang off the lid. One is a paddle. I know I’ve talked to customers that they have the wire one and they’re not being real careful when they’re removing that and they’re snapping it right off.

Russ: You have that, and the paddle wheel is very hard to get the lid off the drum whenever its attached with pretty rigid flex hose. All those other types of sensors seem to be pretty cumbersome and hard to work with. We wanted to go with something that was very small. It doesn’t create another hassle.

Donovan: That sensor is only sticking like a quarter inch out the other side of the barrel.

Russ: On the inside of the drum, yeah.

Jeremiah: It’s like the size of a magic marker, or half of that. It’s about the weight of a magic marker too.

Donovan: And most of it’s at the top, not down into the barrel. It’s pretty sturdy too.

Russ: Yeah, it’s a heavy duty sensor. 

Donovan: So, like I said, Russ is one of our R&D guys. He is out there seeing what the problems are and going, “There has to be a way we can make this better. There has to be a way we can try to solve this problem so I don’t have to get on an airplane from Pennsylvania to California to let somebody know that they have a two by four stuck in their hopper.” Right? Or just that they’re letting their barrel fill up too much. We’re glad to do that, if that’s what needed.

Jeremiah: Yeah.

Donovan: Now, I’m going to circle back around to this. I’ve listened to both of you and the one thing I hear over and over and over again is the number one thing you can do to service your collector is take care of it before you need the service. Preventative maintenance seems to be one of the big things that can probably help solve a lot of issues. Right?

Russ: Yes, it can.

Donovan: So I want to hear Russ’s top three things that people can do for preventative maintenance on their collector. These are the three things, if you’re not going to do anything else, do these three things to help make sure you’re collector is running good, regularly. What could be the three biggest things?

Russ: Well, monitor your differential pressure regularly. Knowing the history of your differential pressure tells you the condition of filters it gives you a trend to follow. So if you have a sudden change, say you’ve been running at one inch of water column and then the next day you’re running at ten. Okay, there is something, some kind of upset condition that happened, and that can help up pin point that kind of thing.

Donovan: Before we get too deep into this, in case anybody doesn’t know, what is differential pressure?

Russ: Differential pressure is a measurement of resistance of airflow across the filters. So we take the pressure before the filters and after the filters and that difference in pressure is the amount of resistance the filters are applying to the airstream.

Donovan: So how much is in the dirty side of the collector and how much is in the clean side of the collector? The pressure difference, right? Am I explaining that well?

Russ: Yeah. The difference between those two pressures is differential pressure. It’s a resistance across the filters, whatever those filters are imposing as a resistance. So that’s monitoring that and being aware is one big thing. Maintaining your pulse valves; I have literally opened up a pulse valve, a diaphragm valve and seen springs broken inside the valve. So the manufacturers do have maintenance intervals recommended. Typically on our collectors we recommend every two years rebuilding.

Donovan: So you’re saying if the springs broken, it’s probably not cleaning your filters, right?

Russ: Yeah, it’s not as effectively cleaning them. 

Jeremiah: Well it’s a ten cent spring, and hundreds of dollars for the filters. Change them.

Donovan: Not only that, but your filters get clogged. Your differential pressure goes up. A ten cent spring could cause your whole system to go down. You could have guys you’re paying $20 an hour to sitting around over a ten cent spring. So, sorry keep going. I didn’t mean to interrupt you.

Russ: Compressed air pressure. Have the correct pressure for your collector. Usually I’ve seen that if you run too light of a compressed air pressure you can not effectively clean the filters. If you go too high on your compressed air pressure, you can damage a filter. Put a hole in it. So it’s very important to get clean, dry compressed air.

Donovan: I know for our machine we have a recommended one. Is that pretty universal across all machines or can that vary from machine to machine.

Russ: Some manufacturers have some slight variances from what we recommend. They’re all pretty close. 

Donovan: So what would be that optimal number for your pressure? If you had to say that you want to be within this range…

Russ: Between eighty and ninety PSI.

Donovan: Eighty and ninety PSI. That’s heading to your tank and that’s where it should be. Well, and I know I’ve heard you say this a bunch of times too, because I’ve sat in on calls. You have to make sure that air is dry, right?

Russ: Yes.

Donovan: That can cause some issues too.

Russ: If you have moisture in your compressed air, that air is being blown directly on the filters, so water, or any kind of moisture – oil – in that compressed air will go directly on the filters and that can cause all kinds of filter problems.

Donovan: Which will make your differential pressure go up.

Russ: Yeah.

Donovan: Your point number one is really a key indicator. If you’re going to do anything on your machine it sounds like you should really be checking that everyday.

Jeremiah: Log your data. They make data loggers too that you can buy. How much are they? They’re pretty inexpensive.

Russ: Some of the real basic ones are probably about eighty dollars. Then you’ve got more advanced systems you can get. You can get up pretty crazy on some of them.

Jeremiah: Honestly sometimes OSHA requires it. DEP might require it. In your particular cause you have to check and see if you have to do it.

Donovan: I’ve seen the two dollar version of a pad and a #2 pencil.

Jeremiah: That works too. You can do it that way.

Russ: Put a clipboard right on the control panel and just write it down.

Jeremiah: The other thing that wasn’t mentioned, because you covered so much but the one thing I was thinking of is its important to keep your hopper clean from dust. So we were talking about the level indicator before. That’s important because if that dust starts to fill up in that hopper and you’re constantly running a full hopper you’re going to re-entrain that dust back on your filters and drastically shorten your filer life. You want to make sure that that’s empty. A lot of people, their indicator for knowing when it’s time to change the drum is when the dust collector starts to spike and their ∆P or their pressure drop. So that’s not a good thing. It’s a lot easier if you just clean it out, depending on what size. Some people have a twenty gallon drum. Some people have fifty-five, or their might be semi-trucks we’ve done where you’re loading out. 

Russ: Self-dumping hoppers or something.

Jeremiah: Yeah, just make sure that there’s a regular PM on it and that it’s cleaned out regularly.

Donovan: I was just talking to someone the other day about their plasma machine. They’re running two ten hour shifts on it. So, that’s what’s happening to them. They keep getting back up. I don’t know if you’ve ever dealt with plasma dust but if it gets on the floor its just a mess. 

Jeremiah: It’s like liquid.

Donovan: It is. So, it is not a fun one to clean up if you have to do that anytime. 

Jeremiah: It stains your hands. It kind of gets in your skin. 

Russ: It’s a mess.

Jeremiah: We’ve both been around that a lot. 

Donovan: No one wants to be pulling that drum out and and just watch it go all over the floor. That’s not ideal. Well, Russ thanks for coming on. I really appreciate it. You have a wealth of knowledge. Jeremiah, thanks for being on too and being our first multi-person podcast. 

Jeremiah: Our podcast is growing numerically.

Donovan: It’s growing. We really appreciate that. Russ, are there any other tips out there that you would like to leave anybody with, other than monitor your differential pressure? I’ve learned that one. 

Russ: When you’re setting up a collector it’s important for filter life to get the airflow right because that wills set the stage for the lifespan of your filters. 

Donovan: Great point. These aren’t just machines that you turn on and they’re ready to go. You’ve got to tune them in a little bit. 

Jeremiah: I want to plug something though.

Donovan: Go for it. 

Jeremiah: I mean, we have a service that does this, right? So what is this service? Tell us about this service.

Donovan: Russ is the head of our ServiceMAXX team. Just like everything else here it’s the “MAXX”. They can do startups. They can do service calls, troubleshoot. Russ is normally really good about being available on the phone. Any more these days a lot of people need a full report on what they have in their facility for either their insurance companies or their jurisdictions that they need to have that. We make very nice reports for that. We have a wealth of knowledge and ability. If you’re interested in that or have an issue and need something, call in. Theres a lot of people here. We’ll get you in touch. We’ll get you on the schedule. That’s us here. It’s not just for Imperial collectors. We can help.

Russ: We’ll service any collector out there.

CMAXX Wipes Custom Countertop Fabrication Challenges

CMAXX Wipes Custom Countertop Fabrication Challenges

Summary

A Kansas City area custom countertop fabrication company had a dust collector that was inadequate.  They were getting fine dust particulate throughout their shop.  They needed a machine that could keep up with multiple CNC routers and filter the fine dust.

Application

The application involves processing a material called Solid Surface. This is a manmade material manufactured from a variety of resins. It is often used to manufacture customer countertops and other kitchen/bath products. This facility was producing dust with two CNC routers and two chop saws.

Challenges

This customer had fine dust particulate bypassing their current dust collector.  They were using an open bag-style dust collector that was not designed to capture fine dust.  The dust generated was potentially combustible, which had to be considered when designing this system.  There were a few specific issues that had to be contemplated during system design.  First, they had no way of putting the dust collector outside because they were landlocked with other companies on every side. Second, they are leasing the building, so they could not put holes through the roof.  Lastly, they needed to have a larger hopper to avoid emptying dust too often, and needed to keep the system under 19’.

The customer’s goals were to filter the dust and have a system that would effectively capture even the finest material from the countertop fabrication operation. In their process, they also had a small amount of wood that was used while cutting the Solid Surface.

Solution for Countertop Fabrication Dust
CMAXX dust collector is the solution for custom countertop fabrication.

Patrick Mulligan of Imperial Systems worked with the project manager on this plan to purchase a new system.  They first started working with Imperial Systems when they found us on the internet.  Patrick reviewed their application and concerns to start the development of this system and then scheduled a site visit to review. With the concern of the potential combustible dust Patrick created a system that included:

  • EIV Explosion Isolation Valve to protect return air in the event of a deflagration
  • Flameless Explosion vent to protect the interior of the building from flame if there was an explosion. They did not go with a chemical explosion suppression agent or a ducted vent to the exterior of the building because the cost was prohibitive.
  • IDA Inline Deflagration Arrestor – The customer wanted to return the air to the building to save on utilities and in addition, their lease caused issues venting outside.  The Imperial IDA system stops a flame front in the event of a deflagration without the need for expensive secondary filters or other outlet isolation devices.
  • DeltaMAXX Filters – MERV 15 rated Nanofiber Fire Retardant IDA filters. These filters are designed to capture the fine particulate

The beginning of the quoting process started in September of 2017 and the customer decided on Imperial Systems being the best partner for this project at the end of February 2018.  After the order was received we designed, manufactured, and installed this turnkey system by the middle of April.

  • CMAXX Model CM004
  • IDA Inline Deflagration Arrestor

ServiceMAXX with Russ & Jeremiah – Dusty Jobs Podcast – S2 E2

A New Year with Chalmer Ritzert – Dusty Jobs Podcast – S2 E1

It is a new year and a new season, and we also got a new studio. Donovan got a minute to talk with Chalmer Ritzert our VP here at Imperial Systems. Chalmer talks about his tier 1 auto manufacturing background and how that helped build the future for a more efficient and better company. He also touches on all of the new things going on in the shop, and how we are always continuing to get better.

     .   

 

                 

 

Narrator: Welcome to the Dusty Jobs Podcast from Imperial Systems, industry knowledge to make your job easier and safer.

Donovan: Hello, and welcome to another episode of the Dusty Jobs Podcast. We’re in our new studio today filming our second season, episode one of the Dusty Jobs Podcast. We’re glad that you guys could all make it back. If you like how this looks and you think we’re doing a good job here we’d be glad to show you our entire facility. We do virtual tours and virtual demos now. If you like that, you can log on to our website and let us know. We’d be glad to give you a full tour. Today as a guest we have our Vice President, Chalmer Ritzert. How are you doing today Chalmer?

Chalmer: I’m good Donovan. How are you?

Donovan: I’m doing great. I’m doing great. Thanks for taking a moment out of your busy schedule to come and tell us a little about yourself and your history. We’re going to talk a little bit about how Imperial is growing and changing and some things we have going on here. 

Chalmer: Absolutely.

Donovan: Yeah, so that’s exciting stuff. Now, if I remember this correctly, you haven’t always been in dust collection your entire career, right? Your career started somewhere else, right?

Chalmer: No, I have not been in dust collection my entire life. I’ve been in manufacturing over twenty five years now. I actually started in the automotive industry. 

Donovan: Now, that was straight out of college?

Chalmer: That was straight out of college. I did my internship, and then I worked for a company in the automotive industry, a tier one automotive manufacturer. We made parts for General Motors, Ford, Chrysler, numerous companies. Our main customers was General Motors. We were actually an injection molding company. We made interior and exterior doors, dashboards, those kinds of things, and then exterior bumpers and side fascias and boilers. You know, all the things you’d see on the outside of cars and we shipped them directly to the automotive manufacturers to put on the cars.

Donovan: Got you. So you guys were in a parts facility and had machines that shot injection into a mold and then it popped out a part? Is that right?

Chalmer: We had enormous injection molding machines. We would make hundreds of thousands of parts a week. If they were exterior we would paint them and assemble them, send them, really, all over the world, but send them to assembly plants where they would put the parts in, sequence them in place, and put the parts on the cars. We would do the same thing with door panels, with dashboards, with center bezels, and those kinds of things.

Donovan: Now, you weren’t working the paint line there or –

Chalmer: No.

Donovan: What was your role?

Chalmer: So when I first started out of college – my degree is actually in environmental health and safety. So, I was first hired as environmental health and safety and there was about seven hundred employees in one facility and we had another seven hundred in another facility and I was responsible to do environmental health and safety. In a painting operation, environmental is a huge piece. Safety is another huge piece. So I kind of cut my teeth as a twenty-two year old kid doing that kind of stuff. I did all the permitting. I did all the reporting. I did all the inspections. I did everything for that. That was kind of what I went to college for. Somewhere along the line I got the opportunity to fill in for the manufacturing manager of the company. He had left and they said, “Hey, will you fill in for this guy?” I was into everything. 

“Will you fill in for this guy while we try to fill the position?” 

I said, “Sure, I would love to fill in for him. The only thing I ask is that you give me an opportunity at the position as well. Thats kind of where everything started. I slowly started to move out of the environmental health and safety. I still maintained all those responsibilities, but I moved into manufacturing manager where I had about four hundred employees at that time and I was responsible for all the injection molding in the company. Three shifts, seven days a week. Just a very high stress, high volume, high quality – you know, I got all my experience in terms of lean manufacturing, in terms of high pressure, in terms of making sure that parts were on time and parts were perfect and those kinds of things early on in my career. I used to have this full head of hair, and then I got into automotive.

Donovan: Didn’t we all?

Chalmer: Now look at me. That is a direct result of being in the automotive industry. Anybody who’s in the automotive industry will tell you that it is one of the most high stress, high volume. It can just be crazy at times.

Donovan: That’s so interesting that from that environmental position into that management position, and I’m sure when you were in that environmental position it just gave you an opportunity to see how everything was working. That just lent itself to probably having a better understanding.

Chalmer: So, for me, first of all I had some people in my life in the company that were great mentors. Second of all, being the environmental health and safety person you’re kind of involved in everything. You’re involved in the day-to-day, doing this and moving people around. You have to be, from a job rotation and ergonomic standpoint, making sure people are fitted for the job and work stations are right. You get into engineering. You get into machine design. You get into all those kinds of things. So I’m involved in the day to day operations and I’m kind of around it all the time. I’m kind of involved. I’m kind of having conversations. I’m doing those kinds of things and the guy that was the manufacturing manager, he literally just left one day. They were kind of high and dry. So they’ve got a three shift operation, four hundred people with no manager, but what was really interesting was the very next day they put me in charge and the very next day they were going to the people in the department saying that I was the safety manager yesterday. Today I’m in charge. Oh, and I’m twenty three.

Donovan: How long were you in that role? Did you stay with that company for a while? Did you move on to another company?

Chalmer: I did. I stayed with that company for eleven years doing that same thing, and that company, unfortunately, closed, which was a sad day. It closed in the mid 2000s. I went from there to a different type of automotive company where they made shipping containers for automotive parts for the tier one suppliers. So when you would make the parts at the tier one supplier they would buy a reusable metal rack and those racks had to be specially designed for all those parts to go back and forth. 

Donovan: So that’s a little more heavy fab?

Chalmer: It’s very heavy fab. So I went from injection molding to metal work. To welding, to that kind of thing, and I was with that company for a while. It was, unfortunately – I laugh, but it also closed. None of this is my fault, but I like to say that I learned a lot of lessons along the way because of the failures of the companies that I was with. You know what I mean? Manufacturing is manufacturing, but you start to learn different processes. From a manufacturing standpoint I was really good at the automotive kind of thing. I could play the game and I could make things happen. I was solid in the environmental portion of things. Who would have guessed that I would ever end up in dust collection?

Donovan: Well, yeah. How in the world did you go from…

Chalmer: Well, it gets even better, because I leave the automotive industry and I actually got involved in the largest company in the world that made promotional products. We made and decorated promotional products. It’s the largest company in the world that does it.

Donovan: When you say promotional product, I’m not even sure I know what that means.

Chalmer: Water bottles, pens, MP3 players…anything that has a logo on it from a company we made.

Donovan: So you’re saying that if I go to a trade show and I’m filling my bag up with stuff, all the stuff is what you guys made?

Chalmer: It’s got to come from somewhere. There was a boom in manufacturing and in the economy in 2006 and 2007, around there, and this company had grown and then they had bought a new facility, and it was just an empty building. They hired me as the plant manager to take over and build that facility up, and I did that. We got up to about three hundred employees in about a 400,000 square foot manufacturing facility. It was pretty neat. It was a real good opportunity for me. In 2009, the economy dropped and the place closed. 

Donovan: We all know what happened in 2008.

Chalmer: So, the company that Chalmer was at closed down. As they were starting to announce that the place was going to close there was an ad in the local newspaper that said “Operations Manager Needed.” I called the number. It was just a little short note. I called the number and the rest is history. Here I am.

Donovan: You got Jeremiah on the other line.

Chalmer: I actually didn’t get Jeremiah. I got the lady who was the accountant at the time. She said, “He’d like to meet with you. Come in and bring your resume.” That kind of stuff. We met a couple of times. It was weird for me because I had been a high volume automotive, you know, doing those kind of things. Lots of employees, hundreds of employees. Managing all the workings and that kind of stuff. I show up for my interview and its a small place. They’ve got, like, eighteen employees at the most. It was just a different vibe altogether. I pulled into the parking lot for that first interview and I’m thinking, “Maybe this isn’t my fit.” Something pulled me inside and I went in and I met with Jeremiah and he and I hit it off. We have a good relationship and we’ve had a good relationship since day one. I was like, “You know what, I’m going to give it a shot.” I’ll be honest with you, it was the best decision I ever made in my life.

Donovan: As a person who works here, we’re glad to have you. We’re glad you chose to come here. You’re a great go-to person for a lot of things.

Chalmer: I appreciate that.

Donovan: And if anybody is out there listening, this is not the announcement of the shut down of Imperial Systems. We are still going strong.

Chalmer: So I would like to reiterate all of the good lessons that I learned by being involved in those. Because I know now not to do those kinds of things, and I know the kinds of things that will make us successful.

Donovan: I’ll speak to this. The success we’ve had in the last year and the way we’ve been able to pull through it as a company, the year 2020. Where that could have went and where we are actually at is incredible. I think that is largely due to you and Jeremiah and everybody here pulling through and using a lot of wisdom in what we have, and knowledge, and experience. In my opinion, I think we came through 2020 stronger than we went into it.

Chalmer: Absolutely. You can say about the pandemic and you can say about the issues that it caused but I believe that issues like those will only make you stronger. I believe we make good decisions. We made some poor ones. I wouldn’t say that we’re perfect, but we made some good decisions. We managed things well. To be honest with you its easy to make good decisions when you have a backing of really good people. I would say that’s the blessing of Imperial Systems for me. It’s the people that work here. 

Donovan: Thanks. I know we all appreciate hearing you say that. I think the other thing that really helped lean towards our success during this year is that our whole model, our whole idea, our whole process here is being a lean manufacturer and not having a lot of waste, and not having a lot of overhead because we’ve taken this lean model. I know that’s something you champion a lot and that’s a lot coming from you and your history in automotive. Can you speak to that and our philosophy on that here?

Chalmer: So, automotive is very high on the lean manufacturing principles. It could be Six Sigma. It could be 5S.

Donovan: Let me pause you for one second, because maybe we’ve got somebody out there listening who doesn’t understand what lean manufacturing is. So we might have to define that for them. Could you give us a quick definition on what lean is?

Chalmer: For me, the best way to describe lean is “how you can do your job easier”. For me that is the most simple, broke down way to explain how we can make the job easier for people. If you’re looking at lean, at the ultimate end of the day, how can you make it easier for that person and eliminate waste, time, or whatever.

Donovan: Taking less steps. Using less material.

Chalmer: Sure. To be honest with you, it’s a lot of common sense is what it is.

Donovan: I think the other thing you say that we talk about – we have a Wednesday morning meeting and one of the things I’ve heard Jeremiah say and you say is, “If there’s something that annoys you, let us know because we will try to fix it.”

Chalmer: Absolutely. Fix what bugs you.

Donovan: Sorry, I didn’t mean to interrupt you there. Keep going. How has that impacted our company, our culture, our community here?

Chalmer: So, when I was involved in those lean manufacturing projects – huge manufacturing projects – and I saw success. Where I saw success was where it was broken down individually and kept as simple as possible. Then I would see that grow. I would say about five to six years ago we were made aware of a local presentation on a process called 2 second lean. I had been skeptical. To a certain extent I can be skeptical about a lot of things. I had been traditionally trained in the Six Sigma, 5S, and those types of processes. I went to this conference and they were talking about this 2 second lean. It is such a simple process. It is so simple. It literally is ‘fix what bugs you’. Jeremiah and I both fell in love with it right from the get go. Its really hard to institute a huge, sweeping thing, but 2 Second Lean is so simple that people just kind of buy into it and go with it. For us, we identify waste. We empower people to identify waste, to look for waste, but the key to it for us is that I don’t want you to come to me and say, “I’ve got a solution. What do you think about doing this?” I want you to come to me and say, “Look what I did, and I made my day better, and I fixed this,” or, “I did this,” or, “I moved this, and I made my day better.” We’re trying to empower people to have the authority to change their own day, to fix things on their own. It’s been hugely successful. They don’t need that kind of permission to move…

Donovan: That garbage can two feet closer.

Chalmer: Yeah, sure. I mean it’s that little stuff that makes such a huge difference in people’s day. When you add that all up at the end of the year the process is so much better. The product is so much better. People are so much happier. 

Donovan: It’s great. If you do a virtual demo with us, and you do a virtual tour with us you can go through and you can see all our carts and how everything is labeled and there are shadow spots where all the tools go. It just helps the guys in the shop to stay organized and allow them to not be wondering where things went and not having to pull all your tools from here to there. Everything’s on a cart on wheels. It’s really neat to see all that.

Chalmer: You just put a little effort behind that stuff. A lot of that stuff is not very expensive to put into place. A lot of that is Harold in assembly doesn’t want to walk twenty feet every five minutes to pick up a different tool. Well put all Harold’s tools right there where he’s working.

Donovan: Let him load the cart up with all the bolts he needs and wheels the whole thing over.

Chalmer: It’s common sense, but if you don’t do it, if you don’t put some effort behind it, you’re going to waste all that time.

Donovan: And I think the other thing that I’ve noticed since I’ve been here is that not only are we willing to do the little things to make our process more lean and efficient and possibly one of the most up to date fab shops in our area, I couldn’t tell you how far, but I know we’ve been making some moves to…I mean, you could talk more about that. You’ve been pretty essential in making all that happen.

Chalmer: Sure. Again, we learn by failing. When you first start out in a business and you’re growing a business, you use what’s available to you to get the job done, and you use what you can afford. As you grow you start to look at different options. We make investments in equipment and processes that make people’s lives easier and that make our product better. What we find is that inevitably every one of those things pay for themselves very quickly. For example, in the olden days, in the first iterations of the CMAXX, those were all wet painted. It was a brutal process to wet paint these things. It wasn’t environmentally friendly. It just wasn’t. So we invested in one of the largest batch powder coating operations around. 

Donovan: When you’re saying large, you could fit…

Chalmer: I could park two of my trucks in our bake oven easily. We make big stuff. We make big stuff. You make big stuff, you’ve got to paint big stuff. We invested, and we did a lot of research on how these various powder coating operations worked and what kind of material handling system we wanted to use and what kind of guns and what kind of powder. There was a lot of research that went into it. We came down to this operation now where we can paint a fourteen or fifteen foot diameter baghouse and put it in our oven and bake it. There are no batch ovens around that could even come close to doing something like that. 

Donovan: Not only did that make our product stronger, it lasts longer. It’s healthier. It’s more environmental, but it also made it faster.

Chalmer: We went from in an eight hour shift maybe painting two rounds with wet paint to painting twelve to sixteen rounds with powder coat, made the quality better, made the product better. In addition, we have zero environmental footprint here. There’s no exhaust from the paint. The wash that we use is environmentally safe. It doesn’t go anywhere. It’s evaporated off. 

Donovan: It’s great for all those guys working on the paint line. It’s healthier for them.

Chalmer: And for the community. Theres nothing going into the water here. Theres nothing going into the air here. We’re very conscious of our environmental footprint.

Donovan: And it cuts our lead times down for our customers. It lets us get our products out to our customers a lot faster. So we’ve done that. That’s our one thing. That’s one of many. You got anything else you want to touch on that we’ve done recently?

Chalmer: So, we invested in a new brake press to try and speed the process up. The newer brake presses are fast and they’re considerably more accurate. What happens is we are able to break parts quicker. We’re able to brake more parts, eliminating welding in a lot of cases, or shortening up the amount of welding that’s necessary. Our parts fit better together. We’re able to brake the parts that we do brake faster. What once was a huge bottleneck in our process is now one of our best manufacturing efficiencies out there. We have just recently gone down the road and started to invest in a laser. For years we’ve used plasma cutting. With plasma cutting you have high accuracy. It does a great job. I’m a huge fan of it. You can do big stuff on it. We needed to pick up some speed and a laser is faster. It has its limitations in terms of size and those kinds of things, but it certainly gives us the speed and the clean up afterwards. Theres no slag or anything on the steel. The cleanup afterwards is considerably better. So we’ve invested in one of the newest and greatest lasers for our facility. It will be installed here before too long. 

Donovan: So if you have a cleaner cut and a better bend, that just takes less time for the guys to weld it. It’s less grinding.

Chalmer: Absolutely. You think about in a normal manufacturing process for sheet metal there’s a lot of grinding and buffing and cleaning up corners and knocking off slag and that kind of stuff. If you can eliminate those kinds prior to paint and stuffs coming out nice and clean we’re making a better product and we’re making it faster.

Donovan: And that’s healthier for the guys too.

Chalmer: It’s absolutely healthier for the guys.

Donovan: Now who was it? One of our welders, his name is slipping my mind. He does all our tubes.

Chalmer: Terry.

Donovan: Terry. Terry was telling me that he got to try a new welder out. Something happened with that. He had to go back to the old one. He felt like he was welding in sand or something. He was telling me it was so slow. What’s this new welder that Terry got?

Chalmer: Terry makes the header tanks for the CMAXXs. He’s the main guy for making the header tanks on the CMAXXs. It can be a tedious process. We had reached out to the welding supplier and they had brought us a demo unit of what’s called a pulse welder. Its just a different way to weld. Terry fell in love with it. It was faster. There was no BBs or slag coming off of the weld, the cleanup or anything like that. It was great. It was a demo. It was a very expensive demo. Terry kept stopping me. “Are we going to keep this? What are we going to do?” Finally we had to give the demo back. So Terry had to go back to his old welder. I remember the day I got to walk out there and tell him, “Hey Terry, your new welder will be here in a week or so,” and he got a new welder. In fact, the new welder worked so well that we’ve actually bought more of those welders for the facility. We’re using them in other areas. Less cleanup, faster, those types of things. There a little more expensive type welder, but they pay for themselves very quickly. So when you’re thinking about things that bug you, and thinking about things that go quicker, and do those kinds of things these are investments that Imperial makes to, even in the downtimes, to try to make our product better, and faster.

Donovan: It benefits our employees. It benefits our environment. It benefits our end users in the end. That’s why we can offer a lifetime warranty on our products because we are so assured of the quality of what’s going out that we feel confident in doing that. 

Chalmer: This facility right now is operating at the highest its ever operated from a quality standpoint, from a speed standpoint, from an efficiency standpoint. It’s never operated like this. 

Donovan: We’re excited for 2021 and continuing to be a lean company, continuing to make those improvements. Who knows? Maybe we’ll have to have you on again in two years and see where we’re at then.

Chalmer: We’re going to continue to invest. We’re going to continue to grow, and we’re going to continue to push forward and be the best. That’s the intention. If we are the best here, then we’re putting out the best product that you can buy.

Donovan: Well, Chalmer I just want to say thanks for coming on. I know you’re busy. You have a lot on your schedule. Thanks for taking a minute to catch everybody up on what’s going on in our company and how we’re continuing to improve and move forward. I just want to say that if you guys enjoyed this and there’s anyone out there listening we have some more backlog that you can listen to too. If you want to subscribe we’re putting these out every month. Like us on Facebook. We put this on every social media aspect out there. Like, subscribe, do that, and until we get a chance to talk to you again stay healthy, stay safe, and have a good day.

Chalmer: And again, thank you.

Narrator: Thanks for listening to the Dusty Jobs Podcast. Breathe better, work safer.

Automotive Parts Manufacturer Solves Robotic Weld Fume Issue

Automotive Parts Manufacturer Solves Robotic Weld Fume Issue

How a Tier 1 Automotive Parts Manufacturer Solved Their Robotic Weld Fume Issue Using the Imperial Systems Shadow Compact Fume Extractor

 

Four Shadow Compact Fume Extractors ready to ship to a robotic weld fume application

 

The Situation with Robotic Weld Fume

An automotive parts manufacturer located in the Atlanta Metro area had an issue with welding fume. It was causing unsightly and unsafe conditions in their robotic manufacturing area.  Not only was there a haze in the air, but dust and fume settling on the walls and floor was causing a cleanliness issue.

The customer had equipment from one of our competitors installed for fume extraction of robotic weld cells. These three cells are where most of the fume was created due to the inadequate dust collectors. They were not handling enough air volume in the space to extract the fume, which was escaping into the facility through the weld positioners.

The Solution

Four Shadow SH06 Compact Fume Extractors were installed on their two types of robotic applications. The first three are installed on fully enclosed robotic welding cells. The fourth Shadow is being used on an enclosed robotic metal brazing cell.

Metal brazing is a process that joins two or more pieces of metal items together by melting or flowing a filler metal into the joint. This process is different than welding because the metal being joined is not being melted. This customer’s specific process generated a larger than normal concentration of weld fume that needed to be filtered from the manufacturing facility.

In the initial problem-solving process, Imperial Systems’ sales manager Justin Badger and a factory rep from HutchCo in Suwanee, Georgia made a site visit in early 2020. They spent time with the customer and the machine operators to determine their goals and see their problems. On the first visit, it became very clear what needed to be done.

First, they determined the size of the enclosed robot area and the expected fume load. With this information, they calculated the amount of air needed to properly ventilate the robot cell and keep escaping fume to a minimum. Next, they reviewed the layout of the building to determine the most convenient spot to install the dust and fume collector.

Once all the above information was gathered, they were able to create a fully engineered solution to solve the robotic weld fume issue. Following several months of COVID-19 related delays, the complete air filtration system was installed in early November 2020.

Success Extracting Robotic Weld Fume

Several weeks following the installation of the equipment, Imperial Systems did a standard follow-up call with the end-user. This was to get feedback on installation service, the sales process, and their satisfaction with the solution.

The customer (who wishes to remain anonymous due to company policy) said, “We are so happy with the results and cannot believe how clean the air in the building is now. Imperial Systems installation technicians were very professional. They worked very well around our extremely busy production schedule and finished ahead of schedule. We plan to have Imperial Systems back in January to install another (Shadow Compact Fume Extractor) machine on a new welding robot.”

Industrial Dust Collector Filter Types

Industrial Dust Collector Filter Types

When you need to replace filters for your industrial dust collector, what kind of filters do you need? There are certainly many filter manufacturers offering lots of choices. However, most dust collector filter types come in a few common materials. So, the type of filter you need depends on your system and type of dust.

Overall, the industrial dust collector filter types listed below are some of the most common. But if you have a special challenge, or questions about your filter needs, our filter experts can help you. We’ve figured out filter problems for other customers so we can help you.

 

Choosing from Many Dust Collector Filter Types

Dust collector filters require replacement on a regular basis. Some people may get a year out of their filters, while some may get a few months. Because of the expense, people might look for the least expensive filters.

We’ll talk about what makes those cheap dust collector filters so cheap, and what other choices you have. The right type of filter will maximize dust collector performance.

 

80/20 POLYESTER CELLULOSE

  • Most basic type of filter
  • 80% cardboard and 20% polyester
  • Lowest MERV rating
  • Poor filter life
  • Not usually recommended

 

NANOFIBER or NANOFIBER FR

  • Treated with a layer of nanofiber
  • Highest MERV rating for standard cartridge filters
  • Improved filter life
  • Captures more particles on the surface
  • FR filters treated with fire retardant

 

SPUNBOND

  • Different basic filter material
  • More resistant to damage
  • MERV rating lower than nanofiber
  • The choice for challenging dust or fumes
  • Can be tried if nanofiber doesn’t work

 

SPUNBOND HYDROPHOBIC/OLEOPHOBIC

  • Specialized material for certain applications
