3M LifeASSURE PFS Series Filter Cartridges

3M LifeASSURE PFS Series PTFE Filter Cartridges combine flow-enhancing construction with a liquid‐validated, bacteria retentive, hydrophobic PTFE filter membrane, providing excellent air flow rates using small assemblies. These filters are used for applications requiring 0.2 micron-sterilization of air, gas, solvents and chemicals in life science industries.

Features of 3M LifeASSURE PFS Series Filter Cartridges

  • Flow-enhancing construction allows air flow with a relatively low pressure drop, resulting in a smaller vent filter assemblies
  • Hydrophobic polytetrafluoroethylene (PTFE) membrane helps prevent pore blockage in vent applications, extending filter lifespan
  • Liquid validation of B. diminuta retention helps provide reliable sterilizing performance in wet or dry conditions
  • 100% forward flow integrity tested prior to release
3M-LifeASSURE-PFS-Filter-Cartridges-Fig3-150x150 Validated PTFE Membrane 
3M LifeASSURE PFS series PTFE Filter Cartridges use a hydrophobic polytetrafluoroethylene (PTFE) membrane, which helps minimize pore blockage from moisture in vent applications. Our filters are validated by a liquid bacterial challenge for complete retention based on the ASTM standard, which provides a high level of reliable sterilizing performance. 
3M-LifeASSURE-PFS-Filter-Cartridges-Fig2-150x75 High Air Flow Construction 
3M LifeASSURE PFS Series Filter Cartridges are constructed to achieve high air flow at a given pressure drop. The PTFE membrane is pleated with polypropylene nonwoven flow-enhancing layers during construction to achieve optimal flow rate performance at low differential pressures.
