Pall Emflon PFR sterilizing-grade filter cartridges feature Pall’s advanced 0.2 µm polytetrafluoroethylene (PTFE) double-layer membranes. They are designed to completely remove bacteria, viruses and particles from air and gas streams, even in the presence of humidity and moisture. Pleated with very high area into sanitary single open-ended (SOE) AB style cartridges, Emflon PFR filters are built to withstand adverse in situ steaming conditions in either the forward or reverse direction. Suitable applications are fermenter inlet air and exhaust venting, sterile process air, and sterile venting of tanks, lyophilizers and autoclaves.
