PTFE Membrane Pleated Filter Cartridge

PTFE Membrane Pleated Filter Cartridge

PTFE Absolute rated membrane cartridges are highly retentive hydrophobic or hydrophilic membrane filters that have been specially designed for critical applications. The PTFE membrane Cartridge in an all-propylene construction provides excellent chemical compatibility and superior flow per surface area as compared to other membrane cartridges.

PTFE cartridge is ideally suited for aggressive chemicals such as acids, bases & solvents. It gives superior flow & pressure drop characteristics for gas filtration & tank venting applications. Are 100 % integrity tested with good particle removal efficiency at 0.1 & 0.2 microns.



  • Hydrophobic PTFE membrane, prevents moisture in venting and wet air filtration.
  • PTFE cartridge has excellent chemical resistance and maximum chemical compatibility.
  • Higher flow rates with lesser pressure drop.
  • Free from binders since end caps are thermally sealed.
  • Absolute rated.
  • Steam Sterilizable.
