Introduction

  Cartridge  filter media is a hydrophobic PTFE membrane, applicable to pre-filtering of gas and solvent and sterilization. Its hydrophobicity is 3.75 times stronger than the erosion resistance capability of ordinary PVDF; thus, filters are applicable to pre-filtering and precise filtration of gas and solvent sterilization. At present, they are widely applied in pharmacy, food, chemical industry, and electronics,  which show excellent heat resistance, they can be repeatedly used in online steam sterilization or high-pressure disinfection. NWF cartridges also have high interception efficiency, high guarantee, and long service life.
