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).
