Water PTFE filter cartridge

The Zhengmai F1T series filter cartridge is made of polytetrafluoroethylene membrane (PTFE) and adopts a manufacturing process that has resistance to organic and inorganic chemical corrosion and natural hydrophobicity. It can be used for filtering strong solvents, highly corrosive liquids, and highly oxidizing liquids. This filter element has good heat resistance and can withstand multiple high-temperature steam sterilization. Each filter element passes integrity testing before leaving the factory.

characteristic advantages

• Natural strong hydrophobicity
• Wide chemical compatibility, resistant to strong acids, strong bases, and strongly polar organic solvents
• Low precipitation material
• High pollutant absorption capacity
• Each filter element undergoes integrity testing before leaving the factory, ensuring more reliable sterilization filtration.

Typical Applications

• Aseptic raw material drug liquid sterilization filtration
• Filtration of organic solvents for active pharmaceutical ingredients
• Strong polarity chemical solvent filtration
• Fermentation gas filtration
• High purity gas filtration in the electronics industry
