Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in precision filtration solutions. Our 0.2μm Pleated PE PTFE Membrane Cartridge 20-inch 316L End Caps High Flow Rate is designed for demanding liquid filtration applications where absolute particle retention and high throughput are critical. This cartridge combines advanced pleated PTFE membrane technology with robust 316L stainless steel end caps, ensuring durability, chemical resistance, and consistent performance over extended service life.
Key Features & Benefits
- High Filtration Efficiency – The 0.2 μm absolute rating removes bacteria, particulates, and microorganisms, meeting stringent purity requirements.
- High Flow Rate – Pleated design greatly increases surface area, reducing pressure drop and allowing higher flow rates compared to standard cartridges.
- 316L Stainless Steel End Caps – Provide excellent corrosion resistance, high mechanical strength, and compatibility with aggressive chemicals and high-temperature applications.
- PTFE Membrane with PE Support – Hydrophobic nature (optional hydrophilic treatment) offers broad chemical compatibility, low extractables, and long service life.
- Pleated Construction – Maximizes dirt holding capacity, extending operational intervals and reducing replacement frequency.
- Versatile Applications – Suitable for pharmaceutical, biotech, food & beverage, electronics, chemical, and water treatment industries.
- Customizable Options – Available with different O-ring materials (EPDM, Viton, Silicone) and connection types (222/226/Flat gasket) upon request.

Detailed Product Advantages
The pleated PTFE membrane cartridge offers a unique combination of high flow rate and absolute retention. The 0.2 μm rating ensures complete removal of bacteria and particles, making it ideal for critical processes such as sterilization filtration, pharmaceutical intermediate purification, and final product filtration. The 316L stainless steel end caps provide superior mechanical strength and corrosion resistance, ensuring a leak-free seal even under high pressure cycles. The cartridge is designed for easy installation and replacement in standard housings with 222/226 O-ring connections.
Industry Applications
- Pharmaceutical & Biotech – Sterile filtration of buffers, solvents, and injectables.
- Food & Beverage – Filtration of wine, beer, juices, and soft drinks.
- Electronics – Ultra-pure water filtration and chemical processing.
- Chemical Processing – Filtration of acids, bases, and organic solvents.
- Water Treatment – Municipal and industrial water polishing.

Frequently Asked Questions
-
Q: What is the difference between hydrophobic and hydrophilic PTFE membranes?
A: Our standard PTFE cartridge is hydrophobic, ideal for gas filtration or venting. For liquid filtration, we can apply a hydrophilic treatment to allow water flow through the membrane. Please specify your requirement. -
Q: Can this cartridge be used for steam sterilization?
A: Yes, the cartridge can be autoclaved at up to 125°C. For in-line steam sterilization, please consult our technical team for proper parameters. -
Q: What is the typical replacement interval?
A: It depends on the feed water quality and operating conditions. Under normal conditions, the cartridge can last 6–12 months. High dirt load may require more frequent replacement. -
Q: Are the end caps available in other materials?
A: Yes, we also offer end caps in polypropylene (PP) or nylon. However, 316L stainless steel provides the best chemical resistance and mechanical strength. -
Q: What O-ring materials are available?
A: Standard options include EPDM, Viton, and Silicone. Other materials like PTFE encapsulated O-rings are available upon request. -
Q: Can I get a sample for testing?
A: Yes, we provide free samples for evaluation. Shipping costs may apply. Contact our sales team for details. -
Q: Is this cartridge suitable for high-viscosity fluids?
A: The high flow rate pleated design can handle moderate viscosity fluids. For very viscous liquids, we recommend a larger pore size or pre-filter. -
Q: What certifications do you have?
A: As a manufacturer, we follow strict internal quality control. Specific certifications such as FDA or NSF can be provided upon request and subject to verification.
