Absolute Rated PTFE Membrane Filter Cartridge

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.

TefTEC Filter Features–Benefits

  • High surface area, single-layer construction provides superior flow rates and minimizes filtration system size
  • 100% Flushed with DI water and integrity tested
  • Meets applicable CFR criteria and USP Class VI Biological Test for Plastics
  • Filters are manufactured in an ISO Class 7 Cleanroom Environment
  • Filters are flushed, tested and packaged in a Class ISO 7 clean room
  • Manufactured using current Good Manufacturing Practices
  • Each filter element stamped with pore size, lot and serial number for identification and traceability
