Benefits of Treatments & Finishes

PTFE Membrane: This treatment can be added to aid in the capture of fine particulate, improve filtration efficiency, and cake release. To learn more about how PTFE works and its benefits, you can access this short video guide.

Singe: The felt is singed on the side where dust cake would accumulate. The process involves removing the loose fiber ends from the filter material. This provides a uniform surface area which improves cake release.

Glazed: A process where the fibers are fused to the body of the filter medium. This helps smooth the surface and improve cake release.
