Filter Media Polyester Calendered Singed FLP-SW

In this dual-action treatment, the media surface is first singed to mechanically remove protruding fibers using a precision thermal process, followed by calendering.

Mechanical Impact
Singing eliminates the hairiness of the needle-punched felt, while calendering flattens the remaining fiber ends. This creates a smooth, clear surface profile.

Technical Benefit
This is the industry standard for improving cake release. By removing the surface fibers that anchor dust, the filter can be cleaned more effectively during pulse-jet cycles, maintaining a lower average pressure drop.
