Welcome to Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer with over 25 years of experience since 1998, exporting annually US$5 million to US$10 million worth of high-quality filtration products across the globe. Our Skeleton Filter Cartridge (316L Stainless Steel, 50 micron, 40 inch) is engineered to deliver exceptional performance in water treatment applications. This robust cartridge combines the strength of 316L stainless steel with a precise 50-micron filtration rating, ensuring reliable removal of suspended solids while maintaining high flow rates. Its durable skeleton design allows for easy cleaning and repeated use, making it a cost-effective solution for industrial water treatment systems.
With a 40-inch length, this cartridge fits standard filter housings and offers extended service life compared to conventional disposable cartridges. Whether you are looking for pre-filtration protection for reverse osmosis membranes, cooling water systems, or process water polishing, this skeleton filter cartridge is designed to withstand harsh operating conditions and provide consistent filtration performance.
Key Features & Technical Specifications
- Material: Premium 316L stainless steel — excellent corrosion resistance, suitable for aggressive water environments including chlorinated, acidic, or alkaline solutions.
- Filtration Precision: 50 micron nominal rating — effectively removes sand, rust, scale, and other suspended particles down to 50 microns.
- Length: 40 inches (1016 mm) — standard size for most industrial filter housings; other lengths available upon request.
- Structure: Skeleton (perforated core) design — provides high mechanical strength, supports high differential pressure, and allows easy backwashing or chemical cleaning.
- Durability: High durability — can be cleaned and reused many times, reducing replacement costs and waste.
- Temperature Range: -20°C to 250°C (depending on gasket material) — suitable for hot water and steam filtration.
- Flow Rate: High flow capacity due to open area and large filtration surface.
- Customization: End cap types (DOE, 222, 226, etc.) and gasket materials (Buna-N, EPDM, Viton) available upon request.

Application Benefits for Your Water Treatment System
- Pre-filtration protection: Installed before RO membranes, UV systems, or ion exchange units to prevent clogging and extend the life of downstream equipment.
- Cost savings: Reusable design — simply backwash or chemically clean the cartridge, reducing filter replacement frequency and solid waste.
- High flow, low pressure drop: The skeleton structure provides a large open area, minimizing energy consumption in pumping systems.
- Corrosion resistance: 316L stainless steel withstands chlorinated water, high salinity, and acidic/alkaline conditions, making it ideal for seawater desalination pre-treatment and industrial wastewater.
- Robust mechanical strength: Can handle high differential pressure without collapsing, ensuring reliable operation even in demanding applications.
- Easy installation: Standard 40-inch length fits most commercial and industrial filter housings; compatible with various end cap configurations.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a skeleton filter cartridge and a pleated filter cartridge?
A: A skeleton filter cartridge typically uses a perforated stainless steel core (skeleton) with a wire mesh or screen layer, offering high strength and cleanability. Pleated cartridges have a folded filter media, which increases surface area but may not be as re-usable. Our skeleton cartridge is designed for repeated cleaning and heavy-duty applications. -
Q: Can this cartridge be backwashed?
A: Yes, the 316L stainless steel skeleton structure allows effective backwashing with water or air. The durable construction withstands repeated backwash cycles without damage. -
Q: What is the maximum operating temperature?
A: The cartridge itself can withstand up to 250°C, but the actual temperature limit depends on the gasket material used. For high-temperature applications, we recommend high-temperature silicone or Viton gaskets. -
Q: Is this cartridge suitable for drinking water treatment?
A: Yes, 316L stainless steel is food-grade and safe for potable water. However, please ensure that the end cap gaskets are also NSF-approved if required for your local regulations. -
Q: What end cap options are available?
A: We offer standard DOE (double open end), 222 O-ring, 226 O-ring, and flat gasket configurations. Custom end caps can be manufactured upon request. -
Q: How long does this cartridge last?
A: The service life depends on the water quality and cleaning frequency. With proper maintenance (backwashing or chemical cleaning), a 316L stainless steel skeleton cartridge can last years, significantly reducing replacement costs. -
Q: Do you provide samples before bulk order?
A: Yes, we offer sample support. Please contact us with your requirements, and we can arrange samples for evaluation. The sample cost is negotiable and can be deducted from the bulk order. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 50 pieces for standard sizes. For customized products, the MOQ may vary. Please contact our sales team for specific details.
