TefTEC P Series Filter Cartridges

PTFE Filter cartridge for critical sterile filtration

TefTEC P membrane cartridges are validated for complete bacterial retention to yield product sterility in biopharmaceutical final filtration applications. TefTEC P cartridge filters are constructed with naturally hydrophobic e-PTFE membrane with polypropylene support layers and components. The sterilizing grade PTFE membrane cartridges are well suited for compressed air applications, fermentation feed air and tank vent applications where absolute microbial retention is critical. Additionally, TefTEC P has demonstrated viral aerosol retention to provide essential protection for final products.
