SHOULD YOU SERVE NANOFIBER WITH SAWDUST? A CHART FOR THE DISCRIMINATING FILTER HOST
Most everyone knows you can’t just go mixing any kind of filter with any kind of dust. After all, some of them certainly don’t pair well together. Fortunately, we here at Imperial Systems have put together a guide for the thoughtful buyer of dust collection filters. With this handy reference, you’ll never have to worry about showing up with the wrong filter for the occasion!

A BIT OF CLARIFICATION:
- Filter bags, or sometimes cyclones, are usually used for materials that are large, fibrous, or big enough to damage a cartridge filter. Bags are also often used when the temperature or humidity is too high for a cartridge filter to handle.
- Metalworking or welding produce fumes. These are very fine particles and an 80/20 media is not efficient enough to catch them. Since many metal dusts are explosive, we do recommend a DeltaMAXX™ nanofiber FR, which is fire retardant. In some applications such as shot blasting, spunbond is used because it is very durable. If your metal fume or dust has grease or oil in it, you may need a special media.
- Dust from ANY of these categories can be explosive. If your dust is explosive or flammable, we will almost always recommend a DeltaMAXX™ nanofiber FR filter as part of an IDA system.
- Organic dust, like food products, may present some special challenges. Organic dust comes in different sizes, and may clump together, absorb moisture, or present other particular problems. Please consult with us about the characteristics of your particular dust.
- If your dust is oily, abrasive, wet, sticky, or otherwise likely to make a mess of a normal dust collector filter, there are a variety of special materials to help. PTFE resists having anything stick to it, while hydrophobic or oleophobic filters will repel water or oil.
