TefloGas Filter Cartridges
Hydrophobic PTFE Membrane · Sterilizing Grade

Cobetter TefloGas® FilterCartridges constructed of hydrophobic PTFE membranes and specially designed for the removal of microorganisms and particles from air and gases. Due to their inherently hydrophobic nature, these filters offer the highest level of sterility even with high volume gas streams, extreme humidity, and stringent in-line stream sterilizations.

Quality and Biological Safety

  • Integrity Testing
  • All cartridges are integrity tested by the aerosol challenge test methods with VALAIR DATA II. Diffusional Flow<16 ml/min at 0.8bar(11.6psi). Water intrusion<1.35ml/min. Values are for cartridges wetted with 60/40 IPA/Water.
  • Steam Sterilization
  • 71-GPF cartridges can be repeatedly in situ steam sterilizal for up to 150 cycles at 121°C,30min at a maximum differential pressure of 0.5 bar
  • Validation
  • 71-GPF cartridges have been fully validated as sterilizing grade
    filter cartridges, for compressed air and gas applications. It passed the DOP test with DH VALAIR DATA II.
