Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer since 1998, specializing in advanced filtration solutions. Our PE with PTFE Membrane Filter Cartridge is engineered to deliver consistent, high-purity filtration for critical applications. With a nominal pore size of 0.2 μm and multiple length options (10", 20", 30", 40"), this cartridge offers exceptional particle retention and chemical compatibility. Whether you need sterile filtration or removal of fine particulates, our product provides reliable performance backed by two decades of manufacturing expertise.
The cartridge combines a robust polyethylene (PE) shell with a hydrophobic PTFE membrane, ensuring excellent resistance to acids, bases, and solvents. The 2.5" outer diameter and standard 226 O-ring end cap design allow easy installation in most filter housings. Operating at temperatures up to 80°C, it is suitable for hot liquid filtration processes. Each cartridge undergoes rigorous quality control to ensure consistent pore structure and bubble point integrity.
Key Features & Benefits
- High Retention Efficiency: 0.2 μm absolute rating ensures removal of bacteria, yeast, and fine particles.
- Broad Chemical Compatibility: PTFE membrane resists aggressive chemicals, enabling use in pharmaceutical, chemical, and food processing.
- Multiple Length Options: Available in 10", 20", 30", and 40" to fit standard housings and reduce change-out frequency.
- Thermal Stability: Maximum operating temperature of 80°C allows hot water sanitization or hot process filtration.
- Low Extractables: PE and PTFE materials minimize leaching, meeting stringent purity requirements.
- Easy Installation: 226 O-ring (double open-end) provides secure sealing and quick change-out.
- High Dirt Holding Capacity: Pleated membrane design increases surface area for longer service life.

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this cartridge?
A: The maximum continuous operating temperature is 80°C (176°F). For short-term cleaning or sanitization, higher temperatures may be tolerated, but please consult our technical team for specific guidelines. -
Q: Can I use this cartridge for hydrophobic applications?
A: Yes, the PTFE membrane is inherently hydrophobic, making it suitable for venting, air filtration, and solvents that are not water-wettable. However, for aqueous solutions, pre-wetting with alcohol is recommended. -
Q: What O-ring materials are available?
A: Standard O-ring is silicone. We also offer EPDM, Viton, and Buna-N as options. Please specify your requirement when ordering. -
Q: How do I select the correct length for my housing?
A: Measure the length of your existing cartridge or the sump depth of your housing. We offer 10", 20", 30", and 40" lengths. If you have a custom length need, we can produce non-standard sizes upon request. -
Q: Is this cartridge suitable for steam sterilization?
A: The cartridge can withstand steam sterilization up to 121°C for up to 30 minutes, but repeated steam cycles may affect the PE shell. We recommend using a dedicated steam-stable cartridge for frequent sterilization. -
Q: What is the typical flow rate for a 10-inch cartridge?
A: Flow rate depends on fluid viscosity and differential pressure. For water at 25°C, a 10-inch cartridge typically delivers 20-30 L/min at 0.2 bar differential. Please request our technical data sheet for detailed curves. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples for qualified buyers. Contact our sales team with your application details, and we will arrange sample shipment. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 100 pieces per length. For smaller quantities, please check with our distributors or request a sample pack.
