In the world of industrial dust collection, maintaining high efficiency and prolonged baghouse filter bag life is crucial. One effective method to achieve this is by applying a pre-coat to the filter bags with specific materials before use. Pre-coating involves applying a material layer to the filter bag media. This creates a base cake that enhances filtration efficiency and extends the filter’s operational life.
The Importance of Pre-Coating
New filter felt media is inherently porous, allowing fine particulate matter, especially those ½ micron and smaller, to pass through. Pre-coating forms an initial layer on the filter media. This significantly increases its efficiency by capturing fine particles and reduces the chances of premature clogging.
Various pre-coat materials are available, including diatomaceous earth, lime, perlite, cellulose, and activated carbon. But the choice of material depends on the specific filtration requirements and the type of filtered particulate. Consulting the filter manufacturer can provide valuable guidance on selecting the most suitable pre-coat material for your particular application.
Preparing and Mixing Pre-Coat Materials
Some pre-coat materials require mixing multiple ingredients to achieve uniform consistency. Ensuring thorough mixing before application is vital for achieving even distribution and optimal filter performance.
Preparing the Baghouse for Pre-Coat Application
Before applying pre-coat to the filters in a baghouse dust collector, certain preparations are necessary:
Remove all previous dust from the baghouse hopper and deactivate the hopper dust removal equipment, such as airlocks.
Deactivate and lockout the baghouse cleaning system to prevent filter cleaning during the pre-coat period.
Pre-Coat Application Methods for Different Baghouse Systems
Negative Pressure Systems: In negative pressure baghouse systems, where the baghouse is under suction, inject the pre-coat through ports or inspection doors in the duct or directly into the dust collector inlet or hopper.
Positive Pressure Systems: For positive pressure systems, where the fan blows into the dust collector, inject the pre-coat into the system ductwork on the suction side of the fan.
Calculating and Applying Pre-Coat
A good rule of thumb is to use one pound of pre-coat for every 20 square feet of baghouse filter media. Operate the system at 50% of the design airflow to the baghouse. This results in an inlet duct velocity of approximately 2000 FPM. Avoid dropping the velocity below this threshold. Then use a pre-coat feed rate of 1/3 pound per minute per 1000 ACFM of reduced airflow. For instance, for a 25,000 ACFM reduced airflow system, the feed rate would be 7.5 lbs./minute.
Inspecting and Ensuring Adequate Pre-Coat Coverage
Isolate each filter compartment and inspect the filter bags to ensure an adequate pre-coat cake, approximately 1/16 inch thick. Then check the collector hopper to confirm that there is not a significant amount of pre-coat dropout.
Once the pre-coating process is complete, increase the air volume to the normal dust collector design flow level. Then turn on the dust removal equipment (airlock). However, do not reactivate the filter bag cleaning cycle until a differential pressure of 3 to 4 inches SPWG is measured across the bags. This step ensures that a seasoned cake of pre-coat has formed on the filter bags before initiating the initial cleaning cycle.
Pre-coating filter bags is a proven method to enhance the efficiency and longevity of dust collection systems. By selecting the right pre-coat material, properly preparing and applying it, and carefully monitoring the process, facilities can ensure their dust collectors operate at optimal performance levels. This not only improves air quality but also extends the life of the filters, contributing to overall operational efficiency.
Pre-coating pleated cartridge media is a standard practice that enhances the performance and lifespan of dust collection systems. This process involves applying a layer of pre-coat material onto the filters to improve their filtration efficiency and protect them from premature clogging and wear.
Types of Pre-Coat Materials
Several types of pre-coat materials are available. Examples include diatomaceous earth, lime, perlite, cellulose, and activated carbon. The choice of pre-coat material depends on the specific filtration requirements and the nature of the filtered particulates. Consulting the filter manufacturer can provide valuable insights into selecting the most appropriate pre-coat material for your application.
Mixing Pre-Coat Materials
Some pre-coat materials may require mixing multiple ingredients. It is crucial to ensure that all components are thoroughly mixed to achieve a uniform consistency before applying the pre-coat to the filters. As a result, this uniformity ensures consistent coverage and optimal performance of the filters.
Application Method
Above all, the simplest method to apply pre-coat to cartridge filters is by installing the filters in the dust collector and activating the system fan. This setup draws the pre-coat material into the collector, allowing it to evenly coat the filter media. Before beginning this process, inspect all pleated cartridge filter elements for defects or damage and clean off any debris. Achieve best results when pre-coating newly installed filters.
Adjusting the Cleaning System
When pre-coating clean cartridge filters for the first time, it is recommended to turn off the pulse cleaning system or set it to “pulse-on-demand” mode. This adjustment ensures that all filters receive an even pre-coat layer before the collector cleaning system begins its pulsing cycle. This helps in achieving a uniform pre-coat distribution, enhancing filter efficiency.
Monitoring Differential Pressure
While applying the pre-coat, it is essential to monitor the filter differential pressure to ensure proper filter efficiency and prevent excessive pressure buildup. Typically, the pressure drop during pre-coating should remain minimal, indicating that the pre-coat is evenly distributed and has not excessively clogged the filter media pores. A slight increase in pressure drop is normal as the pre-coat layer forms, but it should stay within acceptable limits.
Methods of Pre-Coat Application to Cartridge Filters
Apply pre-coat to cartridge filters mounted in the collector using various methods. Use an injection system to introduce metered amounts of pre-coat into the dust collector while it is running. Another method is to apply pre-coat manually by pouring the material directly into an open port on the dust collector inlet or through the flange opening on the dirty air inlet.
Pre-Coat Ratio and Layer Thickness
The ratio of pre-coat to filter area varies depending on filtration requirements and the type of pre-coat material used. A good rule of thumb is to apply a layer of pre-coat between 1/16 to 1/8 inch thick over the entire surface area of the cartridge filters. Allow sufficient time for the pre-coat layer to form and settle onto the cartridge surface, following the manufacturer’s recommendations for the specific pre-coat materials used.
Maintenance and Inspection
Maintaining the filtration system according to the manufacturer’s recommendations is crucial for optimal performance. This includes periodic inspections, cleaning, and replacement of cartridges as needed. Further, regular maintenance ensures that the pre-coat layer remains effective and that the filters continue to operate efficiently.
Calculating Pre-Coat Volume for Cartridge Filters
Calculate the total volume of pre-coat required using the following formula:
Total surface area of all filter media x Desired thickness of pre-coat layer
By following these guidelines, you can maximize the efficiency and longevity of your pleated cartridge filters, ensuring a cleaner and safer working environment.
By incorporating pre-coating into your dust collection system maintenance routine, you can significantly enhance filter performance and extend their service life. Thus, proper selection, application, and maintenance of pre-coat materials are essential for achieving optimal results and maintaining a safe, clean workplace.

Cresswood Shredding Machinery, an Illinois-based company, has been innovating in manufacturing for over 40 years. Their journey began in 1979, crafting residential stoves and fireplace inserts. Over time, they evolved into the realm of industrial furnaces, and then automated boiler systems.
Initially, they utilized German grinders for wood, paper, and plastic to grind material for boiler stokers. After a while, they were not satisfied with the quality of the imported product. So, Cresswood decided to design and build their own grinders – a venture they have successfully undertaken for the past 35 years.
This pivotal shift, however, presented a new challenge: dust and smoke. That is because a crucial aspect of their shredder manufacturing process involved using flex core welding wire, which generated a significant amount of smoke. As Jack Cress, CEO of Cresswood Shredding Machinery, explains, “One of the critical aspects of a weld shop is smoke.”
Cresswood had tried various solutions to combat the welding smoke. They experimented with fume extraction systems attached directly to the welding guns and employed fans to try to pull the smoke out of the building entirely. Unfortunately, none of these methods proved truly effective.
A Breath of Fresh Air: The Imperial Systems Solution
Employee retention is a significant concern across many industries, and Cresswood recognized the importance of fostering a pleasant work environment. Jack explains, “For the last 20 years, it’s been a serious problem to create an environment that employees want to work in.” Clean air was certainly a key piece of that puzzle.
Jeremiah Wann at Imperial Systems listened to Jack’s concerns and proposed a solution: the Shadow Compact Fume Extractor. This innovative system proved to be a significant change for Cresswood Shredding Machinery. Shop employees finally had a smoke-free environment to work in.
“It’s very difficult to get employees and employee retention, and part of that is creating an environment where they want to work,” emphasizes Jack. The impact of the Imperial Systems solution goes beyond just improved air quality; it contributes to a happier, healthier workforce.
Cresswood Shredding Machinery’s story exemplifies the power of innovative solutions. By partnering with a company like Imperial Systems, they were able to address a longstanding challenge and create a more positive work environment for their employees. This not only benefits worker well-being but also contributes to a more productive and successful company overall.
