3M™ LifeASSURE™ PFS Series Filter Capsules 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. A range of capsules are available.
For applications requiring sterilisation of air, gas or aggressive solvents and chemicals, use the optimised 3M™ LifeASSURE™ PFS Series Filter Capsules.
Validated PTFE Membrane
3M LifeASSURE PFS Series PTFE Filters use a hydrophobic 0.2 micron polytetrafluoroethylene (PTFE) membrane, which helps to 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.
High Air Flow Construction
3M LifeASSURE PFS Series Filter Capsules 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.
Engineered for Quality and Reliability
We manufacture LifeASSURE PFS Series filter capsules using all polypropylene structural components (end caps, adapters, media support, inner core and outer cage). Our Quality Management System is approved by an accredited registering body to the ISO 9001:2008 and ISO 13485:2003 Quality Management Systems, and the capsules are 100% forward flow integrity tested prior to shipment. All 3M LifeASSURE PFS Series filter capsules are shipped with a Certificate of Quality affirming compliance with manufacturing quality specifications. Supporting Drug Master File (DMF) documentation is on file with the United States Food and Drug Administration (FDA).
