PTFE Air Filter Film

Product Features

1) PTFE material, featuring high-temperature resistance, corrosion resistance, and aging resistance;

2) Small aperture and uniform, high dust interception efficiency, up to 99.9995%;

3) High porosity and high permeability under high filtration efficiency;

4) Low surface energy, good non-adhesion, easy to remove dust accumulation on the surface;

5) The micropores are small and dense, with the characteristics of surface filtration. It can clear the surface dust by pulse back blowing and washing and restore the performance and long service life.
