PTFE Pleated Filter Cartridge
Our PTFE pleated filter cartridges are engineered to provide exceptional filtration performance for aggressive chemicals, solvents, and high-purity gases. Designed using high-quality hydrophobic polytetrafluoroethylene (PTFE) membrane, these cartridges are ideal for critical applications where chemical compatibility and sterility are essential.
Here’s why professionals choose our PTFE filter cartridges:
Chemical Resistance – Exceptional compatibility with strong acids, alkalis, and organic solvents.
Hydrophobic Membrane – Ideal for gas and vent filtration; prevents wetting in humid environments.
High Particle Retention – Absolute-rated membrane offers reliable filtration from 0.1 to 1.0 micron.
Wide Operating Range – Resistant to high temperatures and suitable for CIP/SIP sterilization.
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.

Frequently Asked Questions (FAQ)
Q1: What makes PTFE filter cartridges different from PP or PES filters?
A1: PTFE cartridges are hydrophobic and chemically inert, ideal for gas filtration and corrosive liquids. PP and PES are suitable for general water and low-chemical applications, but PTFE excels in extreme conditions.
Q2: Can I use your PTFE filters in pharmaceutical production?
A2: Yes. Our PTFE pleated filters meet USP Class VI and FDA standards and are integrity tested, making them suitable for sterile pharmaceutical and biotech applications.
Q3: Are these filters reusable or autoclavable?
A3: Yes. PTFE cartridges are autoclavable up to 121°C and can be reused depending on application and maintenance conditions.
Q4: Do you provide certificates and test reports?
A4: Absolutely. We provide COA (Certificate of Analysis), MSDS, FDA compliance documents, and integrity test reports for each batch.
Q5: What’s your MOQ for PTFE filter cartridges?
A5: For standard models, our MOQ is 50 pieces. For custom specifications, MOQ may vary. Contact us for detailed quotations.
Q6: Can I request a sample?
A6: Yes. We offer free samples for testing. You only need to cover the shipping cost (or we can deduct from bulk order).
