Established in 1998, Anping County Boli Hardware Wiremesh Products Factory is a trusted manufacturer with over two decades of expertise in filtration solutions. We proudly present our 5 inch PES Microporous Filter Cartridge, 0.2μm, with 226 O-ring, High Flow Rate 10 L/min — a precision-engineered product designed to meet the rigorous demands of sterile filtration processes. This cartridge combines advanced polyethersulfone membrane technology with a robust 226 O-ring configuration, ensuring reliable sealing and high-throughput performance. Backed by our annual export value of US$5–10 million, we supply to global markets including North America, Europe, and Southeast Asia, delivering consistent quality and competitive pricing.
Our PES microporous filter cartridge is crafted for critical applications where particle removal down to 0.2 microns is essential. The high flow rate of 10 L/min per cartridge enhances operational efficiency, reducing downtime and energy consumption. Whether you are in pharmaceutical manufacturing, bioprocessing, food & beverage filtration, or electronic chemical polishing, this cartridge offers a reliable barrier against bacteria, particulates, and microorganisms. Below, we detail the key features, technical specifications, and benefits that make this product a preferred choice for professional users.
Key Features & Benefits
- High Filtration Precision: 0.2 μm absolute rating ensures removal of bacteria, yeast, and sub-micron particles — ideal for sterilizing-grade filtration.
- Exceptional Flow Rate: Up to 10 L/min per 5-inch cartridge reduces processing time and system pressure drop, lowering operational costs.
- 226 O-ring Configuration: Standard 226 bayonet cap with an integrated O-ring seal provides leak-free installation and easy change-out in most filter housings.
- PES Membrane Durability: Polyethersulfone exhibits low protein binding, high chemical compatibility (pH 1–14), and thermal stability up to 80°C, making it suitable for a wide range of liquids.
- Low Extractables: The PES membrane is manufactured under strict quality control, minimizing extractables and ensuring product purity — critical for pharmaceutical and food-contact applications.
- Robust Construction: The cartridge is assembled with a polypropylene support layer and end caps, offering mechanical strength and resistance to repeated steam sterilization (if required).
- Versatile Applications: Suitable for pre-filtration, final filtration, bioburden reduction, and clarification in industries such as chemicals, cosmetics, and water treatment.

Why Choose Our PES Filter Cartridge?
The 5 inch PES Microporous Filter Cartridge is designed to deliver consistent performance in demanding environments. Its high flow rate reduces the number of cartridges needed, saving both capital and operational expenses. The 226 O-ring design ensures a secure fit, preventing bypass and contamination. Additionally, the low protein-binding nature of PES makes it ideal for biological solutions where product recovery is critical.
We understand that every filtration application has unique requirements. That’s why we offer customization options: different lengths (10, 20, 30 inch), end cap configurations (222, 226, 226/o-ring, flat gasket), and even non-standard O-ring materials (EPDM, Viton, silicone) upon request. Our team of engineers works closely with clients to ensure the cartridge meets specific process parameters.

Frequently Asked Questions
-
Q: What is the difference between 0.2 μm and 0.45 μm cartridges?
A: 0.2 μm cartridges are classified as sterilizing-grade, capable of removing bacteria like Pseudomonas diminuta. 0.45 μm is typically used for particle removal or clarification. Our 0.2 μm PES cartridge is suitable for applications requiring absolute sterility. -
Q: Can this cartridge be used with organic solvents?
A: PES membrane has good chemical resistance to many organic solvents, but compatibility should be verified for specific solvents. For aggressive solvents like strong acids or bases, we recommend consulting our technical team. Options include PTFE or PVDF membranes. -
Q: How do I install the 226 O-ring cartridge?
A: The 226 configuration features a bayonet lock with an O-ring seal. Insert the cartridge into the housing, align the tabs, and twist clockwise until locked. Ensure the O-ring is properly seated to prevent leakage. Detailed instructions are provided with each order. -
Q: What is the typical lifespan of this cartridge?
A: Lifespan depends on feed water quality, flow rate, and operating pressure. Under typical conditions (pre-filtered water), replacement is recommended when differential pressure reaches 2.0 bar or when flow declines significantly. For high-purity applications, periodic integrity testing is advised. -
Q: Does the cartridge meet FDA or USP Class VI requirements?
A: Our PES membrane is manufactured from raw materials that are commonly used in pharmaceutical applications. We can provide extractables data and biocompatibility test results upon request. However, we do not include unverified certifications. Please contact us for specific documentation needs. -
Q: Can I get a free sample before bulk order?
A: Yes, we offer sample cartridges for evaluation. Please contact our sales team with your application details, and we will provide a sample along with a technical datasheet. Shipping costs may apply for international orders. -
Q: What packaging options are available?
A: Standard packaging: individually sealed in polybags, then packed in carton boxes. For bulk orders, we can provide custom packaging or bulk bundles. Each cartridge is labeled with part number, lot number, and manufacturing date. -
Q: Do you support custom end cap configurations?
A: Absolutely. We can produce cartridges with 222, 226, flat gasket, or even double O-ring end caps. Minimum order quantity may apply. Contact us to discuss your housing specifications.
