PFA

PFA® Filter Cartridges

All Fluoropolymer Constructed

PFA® Filter Cartridges are composed of an expanded PTFE membrane and PFA cage, core and support. These filters are specially designed for applications with extremely aggressive environments including strong acids, alkalis and solvents and high temperatures .

Among this series filters, validated sterile grade is also available, named as PFA-T which is highly recommended for strict pharmaceutical applications .

Features and Benefits

  • 100% all Fluoropolymer construction
  • High filtration performance including high flow rates and low pressure drops
  • Available in pre-wetted package if requested

Quality Standards

  • Integrity Test correlates to ASTM F838-05 Bacterial Challenge Test (applicable to PFA-T filter only)
  • Each filter is individually Integrity Tested prior to leaving the factory(applicable to PFA-T filter only)

* PFA-T available in 0.22um only.

* PFA filter is not 100% integrity tested, it is designed as a pre-filter or final filter when validation and sterility guarantee are not necessary.

* Please Select the SS insert end cap if the filter will be sterilized by SIP.
