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 sterilising performance in wet or dry conditions
100% forward flow integrity tested prior to release
3M™ LifeASSURE™ PFS Series Filter Cartridges have a flow-enhancing construction with a liquid‐validated, bacteria retentive, hydrophobic 0.2 micron PTFE filter membrane. Our PTFE filter provides excellent air flow rates using small assemblies.
For applciations requring 0.2 micron sterilsation of air, gas, solvents and chemicals in life science industries, use 3M™ LifeASSURE™ PFS Series Filter Cartridge.
Validated PTFE Membrane
3M LifeASSURE PFS series PTFE Filter Cartridges use a hydrophobic polytetrafluoroethylene (PTFE) membrane, which helps minimise 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 sterilising performance.
High Air Flow Construction
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.
