TefTEC™ Series Filter Cartridges

TefTEC™ Series Filter Cartridges

Absolute Rated PTFE Membrane Filter Cartridges TefTEC cartridge filters are constructed with naturally hydrophobic PTFE membrane and polypropylene support

layers and components. The HIMA retentive PTFE

membrane offers superior hydrophobicity and water intrusion resistance compared to PVDF and  polypropylene membranes, and the cartridge construction offers a cost-effective alternative to all-fluorocarbon filters.

 TefTEC filters are ideal for gas/vent applications and the filtration of aggressive chemicals and solvents.


•High surface area, single-layer construction provides superior flow rates and minimizes filtration system size

•100% Flushed with 18 M- cm DI water and integrity tested

•Filters are manufactured, flushed, tested and packaged in an ISO Class 7 Cleanroom Environment.

•Each filter element stamped with pore size, lot and serial number for identification and traceability.

•Complete qualification guide available

•Available prewet for use with aqueous based chemicals
