Reclaim system performance of air filters for powder coating in any powder coating application can dramatically affect overall operating efficiencies. The effectiveness of these operations can be further enhanced with cartridge-filter technology designed to reduce waste and improve
powder-booth performance.

Air filters for powder coating, developed specifically for our customers, include an innovative pleat design, optimum pleat number and spacing, and a unique, filter media dimpling process. This technology provides and maintains maximum effective surface area throughout reclaim operations for the highest operating efficiency and performance available.

Powder coating is increasingly accepted as the preferred finishing process for many applications. Increasingly stringent environmental regulations, rising costs in all areas, and demands by consumers for better quality and more durable products are among the challenges facing today’s finishers. Powder coatings provide a solution to these challenges and others. Powder coating is the technique of applying dry paint to the component.

The powdered paint is normally applied by using a powder feed system and gun to electrostatically charge and spray the powder onto the part. For some applications, the part being coated is dipped into a fluidized bed of powder. The coated part is then heated in an oven, or via infrared panels, to melt and cure the paint. During the curing process, a chemical cross-linking reaction is triggered and it is this chemical reaction that gives the powder coatings many of their desirable properties.

Air filters play a crucial role in powder coating operations by capturing overspray powder, preventing environmental contamination, and ensuring a clean and safe work environment. They are an essential component of powder coating booths, effectively removing airborne particles and maintaining air quality.

Types of Air Filters for Powder Coating

  1. Pleated Filters: These filters are constructed with pleated media that increases the surface area for dust capture, enhancing their efficiency in removing fine powder particles.
  2. Cartridge Filters: These filters are housed in cylindrical cartridges and offer high filtration efficiency, making them suitable for high-volume powder coating operations.
  3. Pocket Filters: These filters feature pockets of media that trap dust particles as air passes through, providing effective filtration for medium to large particles.
  4. Panel Filters: These filters are constructed with flat panels of media and are often used as pre-filters to remove larger particles before air enters more efficient downstream filters.

Selection Criteria for Air Filters in Powder Coating

  1. Filtration Efficiency: Choose filters with a high efficiency rating to effectively capture overspray powder and maintain air quality.
  2. Airflow Resistance: Ensure the filters have a low airflow resistance to minimize pressure drop and maintain adequate ventilation.
  3. Filter Size and Shape: Select filters that match the dimensions of your powder coating booth and fit properly into the filter housings.
  4. Media Material: Choose filters with media that is compatible with the type of powder being used and can withstand the operating conditions of the powder coating booth.
  5. Maintenance Requirements: Consider the ease of cleaning or replacing the filters when selecting a suitable option for your powder coating setup.

Combining an innovative filter pleat design with EMS Powder Coating Equipment’s exclusive process of filter media dimpling, the air filters for powder coating deliver the maximum effective surface area throughout a powder coating reclaim system operation.

The dimpled filter media is self-supporting, requiring no metallic screens or armature to prevent pleats from pinching or ballooning during the process. This provides unobstructed airflow across the entire surface area for maximum filtration efficiency and lower pressure drop across the filter.

The absence of any pleat-supporting screens and a larger number of pleats provide maximum overall filter surface area. Rounding off the pleat tips further increases the effective filtration surface. This results in a slower rise in pressure drop, reduced load on the booth fan, and improved overall reclaim system operation.

Powder Coating Cartridge Filter

In comparison testing, a typical paper cartridge filter retained 14 pounds of powder, which must be discarded when the filter is replaced. The air filters for powder coating retained only three pounds of powder, reducing waste by as much as 80 percent. Such significant savings are due to the optimized pleat count and spacing of the air filters for powder coating.

The excellent powder release characteristics of the 100 percent polyester filter media significantly reduce powder retention and waste. The dimpled media of The air filters for powder coating eliminate ballooning of the pleats and trapping of powder during reverse pulsing. This improves the effectiveness of pulsing, allowing the air filters for powder coating to work at a lower average static pressure drop over the life of the filter, and keeps more powder in the process.

Field tests show that lower pulsing pressure is required to maintain the desired pressure drop across the air filters for powder coating. Pulsing frequency is also reduced in systems equipped with a “pulse-on-demand” feature. Reductions in pulsing pressure and frequency help prolong filter service life and lower compressed air consumption for a better operating economy.
