PTFE Pleated Filter Cartridge
OVERVIEW
The PTFE pleated filter cartridge is a high-performance filtration solution engineered for demanding applications requiring chemical resistance, thermal stability, and absolute cleanliness. Made using hydrophobic polytetrafluoroethylene (PTFE) membrane media, this cartridge offers superior performance in filtering corrosive gases, aggressive solvents, ultrapure water, and sterile air. It is widely used in the pharmaceutical, biotech, chemical, and semiconductor industries where reliability and sterility are critical.
PTFE (Polytetrafluoroethylene) is known for its extreme chemical inertness, hydrophobic nature, and high thermal resistance. When this material is used in pleated membrane cartridges, it delivers a unique combination of features that ordinary filter media like polypropylene or PES cannot match.
Unlike traditional filters that degrade in contact with aggressive fluids, PTFE pleated filters remain stable and effective, ensuring consistent filtration in the harshest environments. Their hydrophobic property also makes them ideal for air and gas filtration, especially in sterile or high-purity applications.

PTFE Pleated Filter Cartridges Highlight
✅ Broad Chemical Compatibility：The PTFE membrane resists degradation from acids, bases, oxidizers, and most organic solvents. This allows the cartridge to be used with confidence in highly corrosive chemical filtration
✅ Hydrophobic Membrane for Air and Gas Filtration：The naturally hydrophobic structure of PTFE prevents wetting, making it the optimal choice for sterile gas and vent filtration, including in fermenters, air tanks, and bioreactors.
✅ High Temperature Endurance：Our PTFE cartridges can operate continuously at temperatures up to 120°C (248°F), with sterilization options including autoclaving and steam-in-place (SIP) procedures.
✅ Absolute Rated Filtration：Available in micron ratings as low as 0.1 µm, these filters provide absolute particle retention, ensuring no compromise on critical process purity or sterility.
✅ Low Extractables and Particle Shedding：The cartridge materials are designed and manufactured to minimize extractables and prevent particle shedding, which is vital in pharmaceutical and microelectronics applications.
These cartridges are resistant to:
Acids
Alkalis
Organic solvents
Industrial process fluids
1. Pharmaceutical and Biotechnology
PTFE filter cartridges are extensively used in the production of sterile injectable drugs, vaccines, and culture media. They are perfect for filtering aggressive cleaning agents, solvents, and ensuring contaminant-free air in aseptic processing environments.
2. Semiconductor Manufacturing
In microelectronics and semiconductor plants, ultrapure water and gas purity are critical. The PTFE pleated filter’s ultra-clean and non-shedding construction makes it suitable for high-purity DI water and chemical filtration.
3. Chemical Industry
Ideal for use in acid recovery, solvent filtration, and chemical polishing, these filters maintain integrity even in aggressive conditions where other filter media break down.
4. Food and Beverage
Used in critical gas and compressed air filtration to maintain product purity and safety. PTFE cartridges are also applied in venting tanks and fermenters to protect the process from microbial contamination.
5. Air and Gas Sterilization
In sterile processing facilities and cleanrooms, hydrophobic PTFE filters are essential for bacteria and virus retention in compressed air, CO₂, and other process gases.
