3M™ LifeASSURE™ BFS Series Filter Cartridges are PTFE microporous hydrophobic straight pleat membrane filters used in processes requiring 0.2 µm sterile and microbial-rated air filtration for food and beverage, microelectronics and other industrial applications. Offering excellent air flow for vent filter assemblies, they prevent moisture blockage to increase the throughput and filter life.

3M™ LifeASSURE™ BFS Series Filter Cartridge

High efficiency contaminant reduction.

3M™ LifeASSURE™ BFS Series Filter Cartridges are made with a hydrophobic PTFE membrane. The inner and outer non-woven polypropylene layers provide upstream and downstream support which allow better flow access through the membrane pleats. A second polypropylene downstream flow distribution layer further enhances airflow. Available in 10, 20 and 30-inch sizes, these filter cartridges have a standard straight pleat and a filter rating of 0.2 µm, allowing them to be used for sterilization.

The cartridge hardware components consist of an inner and outer cage made of molded polypropylene. End cap adapters and O-ring adapters are also constructed of polypropylene and contain a 316 stainless steel ring or an embedded polyethersulfone (PES) core for structural stability. All filter cartridge components are assembled by thermal bonding.

    Validated PTFE construction.

    3M™ LifeASSURE™ BFS Series Filter Cartridges use a hydrophobic polytetrafluoroethylene (PTFE) membrane that helps minimize moisture-related pore blockage and achieves a high air flow rate in vent applications.

  • Funnel and document inside blue-green gradient circle icon
    Broad chemical compatibility.

    The polypropylene construction and PTFE media of 3M™ LifeASSURE™ BFS Series Filter Cartridges provide broad chemical compatibility for use in a wide range of industrial applications.
