Product 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.

Features

  1. Highly safe sterilization, ensuring 100% filter eficiency in humid environment during gas filter.
  2. Strong hydrophobicity, passing water intrusion test, avoiding residues due to the integrity of solventwetting test.
  3. Chemical compatibility, endurable to acid, alkali, and organic solvent.
  4. Passing 100% integrity test, quality safe and reliable.
  5. Sterilization of solvents such as esters alcohols acids and alkalis.
  6. Liquid filter precision specific to 0.2um, for gas filter, single layer: < 0.01umф, double layer. .0.003umф.
  7. Single or double layer, large filter area, small pressure difference, large throughput long service life.
  8. Cartridge independently numbered, production batch traceable.
  9. Pre-filtering gases of storage tanks, respirators, and femment tanks.
  10. Particle filtering Sterilization and filtering of compressed air or gases in medicine and food industries.
