Safesure AFB Hydrophobic PTFE Gas Filter (CAT#: STEM-BC-0031-ZJF)

Safesure AFB is a hydrophobic PTFE gas filter designed for sterilizing filtration under dry or humid conditions. The PTFE membrane is further treated to provide strong hydrophobicity and oleophobic performance. It is suitable for fermentation tank breathing, storage tank venting, compressed air, oxygen, nitrogen, and disposable system applications. The filter uses polypropylene support and housing components with 316L stainless steel or PBT interface liners for cartridge formats. A reinforced temperature-resistant polypropylene center core supports improved thermal and pressure stability. The product supports repeated online steam sterilization and autoclave sterilization for cartridge formats. Capsule formats support autoclave sterilization according to configuration. Each filter is integrity tested and traceable for process control.
