As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory (established in 1998), we present our PE with PTFE Membrane Filter Cartridge – a high-performance filtration solution designed for demanding liquid applications. With an annual export value of US$5–10 million and serving global markets across North America, South America, Europe, Asia, Africa, and Oceania, our factory ensures consistent quality and reliable supply. This 0.2μm filter cartridge integrates a durable polyethylene (PE) support core with a hydrophobic PTFE membrane, providing excellent chemical resistance and precise particle removal. We offer free sample testing to help you evaluate performance before bulk purchase, backed by our commitment to quality guaranteed.
Key Features & Technical Specifications
- Membrane Material: PTFE (polytetrafluoroethylene) – inherently hydrophobic, excellent for aggressive chemicals and high-purity applications.
- Support Structure: Polyethylene (PE) – provides robust mechanical strength and prevents collapse under differential pressure.
- Pore Size: 0.2 μm – suitable for sterilization, bacteria removal, and fine particulate filtration.
- Cartridge Dimensions: Length 20 inches (508 mm), Outer Diameter 2.5 inches (63.5 mm) – standard industry size for easy retrofit.
- End Cap Configuration: 222 O-Ring (double open end or flat cap with O-ring) – ensures leak-proof sealing in most housings.
- Filtration Area: Typically 0.6 m² per 20-inch cartridge, providing high dirt-holding capacity.
- Operating Temperature: Up to 80°C (176°F) for continuous use; higher intermittent temperatures possible with specific fluids.
- Flow Rate: 0.5–5 GPM per cartridge depending on viscosity and differential pressure.
- Chemical Compatibility: Resistant to acids, alkalis, solvents, and oxidizers – consult our compatibility chart for specific fluids.
- Integrity Test: Optional bubble point or pressure hold test available upon request.

Product Advantages & Benefits for Your Business
- High Purity Filtration: The PTFE membrane ensures low extractables and non-fiber releasing, meeting requirements for pharmaceutical, biotech, and semiconductor industries.
- Chemical Resistance: Withstands harsh chemicals including strong acids, bases, and organic solvents, making it versatile for a wide range of applications.
- Long Service Life: The PE support prevents collapse under high differential pressure, and the PTFE membrane is easy to clean (backwashable if required), reducing replacement frequency.
- Leak-Proof Sealing: The 222 O-ring design provides reliable sealing in standard housings, minimizing bypass and ensuring consistent filtration quality.
- Customizable Options: Available in various lengths (10, 20, 30, 40 inches), end cap configurations (222, 226, DOE, SOE), and O-ring materials (Viton, EPDM, Silicone) – we can tailor to your housing.
- Free Sample Testing: We offer free samples for performance evaluation – simply provide your process conditions, and we will send cartridges for your testing.
- Cost-Effective Solution: Competitive pricing without compromising quality, backed by our 26+ years of manufacturing experience.
- Global Logistics: We ship from multiple Chinese ports (Tianjin, Qingdao, Shanghai, Foshan) with fast lead times and reliable export documentation.
Typical applications include sterile filtration of pharmaceutical liquids, point-of-use filtration in electronics manufacturing, food and beverage clarification, chemical processing, and water purification. The 0.2μm absolute rating ensures removal of bacteria, yeast, and particulate matter, delivering consistent product quality.

Frequently Asked Questions
-
Q: What is the difference between PTFE membrane and other membranes (e.g., PES, PVDF)?
A: PTFE is inherently hydrophobic and offers excellent chemical resistance to almost all solvents, acids, and bases. It is ideal for aggressive chemicals and high-purity applications where extractables must be minimized. PES and PVDF have different chemical compatibility – PTFE is generally more robust. -
Q: Can this cartridge be used for air/gas filtration?
A: Yes, the PTFE membrane is hydrophobic and can be used for sterile air filtration, vent filters, and gas purification. However, the PE support may not be suitable for high-temperature gases – please consult our technical team for specific conditions. -
Q: What is the recommended differential pressure for maximum flow?
A: For water at 25°C, a typical differential pressure of 0.2–0.5 bar (3–7 psi) yields optimal flow. Maximum differential pressure is 4.0 bar (58 psi) at 25°C. Higher differential pressure may reduce cartridge life. -
Q: How do I know if the 222 O-ring will fit my housing?
A: The 222 O-ring configuration is a standard industry size (2.0-inch diameter O-ring, sometimes with a flat cap). We recommend measuring your housing’s O-ring groove or referencing your existing cartridge. We can also provide 226 O-ring or DOE (double open end) options. -
Q: Do you provide free samples for testing? How long does it take to receive them?
A: Yes, we offer free samples for qualifying customers. Typically, samples are shipped within 3–5 working days after confirmation of your request and shipping address. Delivery time depends on the courier service (e.g., DHL, FedEx, UPS). -
Q: What is the shelf life of these cartridges?
A: When stored in a cool, dry place away from direct sunlight, the shelf life is generally 2 years from the date of manufacture. PTFE membrane does not degrade over time like some other materials. -
Q: Can I get a custom length or different O-ring material?
A: Absolutely. We offer customization of length (10, 20, 30, 40 inches), end cap types (222, 226, SOE, DOE), O-ring materials (Viton, EPDM, Silicone, Buna-N), and even different pore sizes (0.1μm, 0.45μm, 1μm). Please contact our sales team with your requirements. -
Q: Do you have any quality certifications?
A: Our factory follows strict quality control procedures. While we do not claim specific certifications not mentioned in our profile, we can provide a certificate of analysis (COA) for each batch and perform integrity tests as requested. We adhere to international manufacturing standards.
