PTG Series Filter Cartridges feature hydrophobic polytetraflu-oroethylene (PTFE) membrane which offers excellent chemical compatibility and is an ideal choice as an air/gas vent filter. Specialty-grade polypropylene hardware and support layers offer enhanced resistance to oxidation.  Is well-suited as an air vent filter for fermentation processes.  Integrity testable by water intrusion (WIT).

 

Features

  • Absolute 0.2µm filtration efficiency.
  • 100% integrity tested.
  • Receives a final rinse with 18MΩ ultrapure water to assure cleanliness.
  • Excellent chemical compatibility.  Tolerates pH 1 to 14. Hydrophilic membrane resists wetting.

 

Applications

  • Sterile process air
  • Aseptic packaging
  • Tank air vents
  • Fermentation process feed air
  • Compressed gases
  • Tolerates aggressive fluids: solvents, strong acids, & bases
