2021 Good Quality Polypropylene Filter Bag Factory – Medical grade 0.22um hydrophobic ptfe membrane air filters – kinda

NWF series cartridges filter media is a hydrophobic PTFE membrane, applicable to the pre-filtering and sterilization of gas and solvent. PTFE membrane has the strong hydrophobicity, its water erosion resistance capacity is 3.75 times stronger than the ordinary PVDF, so applicable to gas pre-filtering and precise filtering and solvent sterilization, they are widely applied in pharmacy, food, chemical industry, and electronics. NWF cartridges show excellent heat resistance, they can be repeatedly used in online steam sterilization or high-pressure disinfection. It also have high interception efficiency, high guarantee, and long service life.
