  3. High Particle Retention – Absolute-rated membrane offers reliable filtration from 0.1 to 1.0 micron.

  4. Wide Operating Range – Resistant to high temperatures and suitable for CIP/SIP sterilization.

  5. Manufactured in ISO-Certified Cleanrooms – Every cartridge is integrity tested and meets international standards.

What is a PTFE Pleated Filter Cartridge

A PTFE pleated filter cartridge is a type of industrial filtration element made with hydrophobic PTFE membrane media, designed to provide excellent filtration for highly corrosive liquids and gases. The PTFE (Polytetrafluoroethylene) material is well-known for its superior chemical inertness, thermal stability, and non-stick surface properties, making it ideal for use in harsh and sterile environments.

Unlike standard polypropylene or PES filter cartridges, PTFE pleated cartridges are resistant to hydrofluoric acid, strong bases, solvents like DMF and DMSO, and are widely used in chemical manufacturing, semiconductor processing, pharmaceuticals, and lab gas filtration.

The pleated structure of the membrane significantly increases the surface area, improving flow rate, particle holding capacity, and filter longevity, ensuring stable performance even under continuous high-stress conditions.

  • Superior Chemical Compatibility
    Handles aggressive chemicals including nitric acid, hydrochloric acid, ammonia, and strong oxidizers.

  • Hydrophobic PTFE Membrane
    Repels water and moisture, ensuring dry gas flow and preventing bacterial ingress.

  • High Temperature Resistance
    Operates continuously up to 85°C; steam sterilizable up to 121°C.

  • Absolute-Rated Filtration
    Micron ratings from 0.1μm to 1.0μm provide reliable and consistent retention.

  • Long Service Life
    Large surface area pleating improves dirt-holding capacity and reduces change-out frequency.

  • Integrity Tested & Cleanroom Assembled
    100% bubble point tested and built in ISO-class sterile conditions.

PTFE pleated filters are essential in any application involving corrosive fluids, gas filtration, and sterile environments:

  • Pharmaceutical & Biotech: Sterile air/gas filtration, solvent filtration before formulation.

  • Electronics & Semiconductors: Ultrapure chemical filtration and cleanroom gas handling.

  • Chemical Processing: Filtration of aggressive solvents, acids, and bases.

  • Food & Beverage: CO₂ and compressed air filtration in beverage processing.

  • Laboratories & Analytical Instruments: Sample preparation, gas line protection, solvent purification.
