Product Introduction：
The PTFE folding filter cartridge uses polytetrafluoroethylene microporous membrane as the filtration medium, which has the best chemical compatibility among all membrane materials
Sexual and thermal stability, able to withstand the majority of strong acids, strong bases, and organic solvents (note: not applicable to molten alkali metals and some high-temperature perfluorinated compounds).
The PTFE series is divided into hydrophobic type (natural PTFE membrane) and hydrophilic type (modified by hydrophilic treatment) to meet the filtration needs of different media. Hydrophobic PTFE filter element is the preferred filter element for gas sterilization filtration, widely used in air filtration of fermentation tanks, sterile filtration of compressed gases, and sterile tank respirators; Hydrophilic PTFE filter cartridge is suitable for precision filtration of highly corrosive liquids and high-purity chemicals.
Application fields:
Chemical industry: precision filtration of strong acids, strong bases, organic solvents, high-purity chemical reagents
◎ Gas filtration: Sterilization filtration of sterile air, compressed air, nitrogen, and carbon dioxide in fermentation tanks
◎ Pharmaceutical industry: sterile raw material filtration, strong corrosive liquid terminal filtration
◎ Food and beverage: Baijiu sterilization, high acidity beverage, precision filtration of edible oil
◎ Equipment matching: sterile storage tank respirator, high-pressure sterilization cabinet air filtration
Product Features:
◎ Optimal chemical compatibility (fully compatible)
◎ Highest temperature resistance, capable of filtering high-temperature media
◎ Hydrophobic/hydrophilic dual type optional
◎ First choice for gas sterilization and filtration
