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.

Key Features
 Highly safe sterilization, ensuring 100% filter efficiency in humid environment during gas

filter, 0.2um filter rating in liquid, for gas filter, single layer: < Φ0.01μm; double layer: < 0.003μmΦ;

◇ Strong hydrophobicity, passing water intrusion test, avoiding residues due to the integrity of solvent wetting test;

◇ Single- or double-layer; large filter area, small pressure difference, large throughput, long service life;

◇ Excellent chemical compatibility, endurable to acid, alkali, and organic solvent;

◇ Cartridge independently numbered, production batch traceable;

◇ Passing 100% integrity test, quality safe and reliable;
