Hydrophobic PTFE Filter Cartridge

The Hydrophobic PTFE Filter Cartridge is an absolute-rated, high-temperature filtration solution designed for air, gas, and non-aqueous aggressive media. Its hydrophobic PTFE membrane provides exceptional retention efficiency, capturing particles and microorganisms as small as 0.01 μm—offering sterile, contaminant-free gas streams.

Engineered for durability under extreme operating conditions, it is ideal for venting, sterile air filtration, gas purification, and solvent vapor applications.
