As a leading manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to present our Skeleton Core Filter Cartridge — a robust filtration solution designed for demanding industrial applications. With over two decades of expertise in wire mesh and filter element production, we ensure that every cartridge delivers consistent performance, structural integrity, and full compliance with international standards. Our filter cartridges are accompanied by a Mill Test Report (MTR) to guarantee material traceability and quality assurance, giving you confidence in every purchase.
The skeleton core design provides exceptional mechanical strength, allowing the cartridge to withstand high differential pressures and flow rates without collapsing. Whether you need filtration for water, chemicals, oils, or food products, this cartridge offers reliable contaminant removal while maintaining low pressure drop. Our manufacturing process follows strict quality control protocols, and each unit is tested before shipment.
Key Features & Benefits
- Reinforced Skeleton Core: Inner and outer support layers prevent deformation under high flow or pressure, extending service life.
- Wide Material Compatibility: Available in stainless steel (304/316L), polypropylene, or other materials to suit different fluid chemistries.
- High Dirt Holding Capacity: Pleated filter media maximizes surface area, allowing longer operation between changeouts.
- Mill Test Report Provided: Full traceability of raw materials, including chemical composition and mechanical properties, upon request.
- Standard Compliant Manufacturing: Produced in accordance with ISO 9001 quality management system (factory certified), ensuring consistent dimensions and performance.
- Versatile End Caps: Options include flat, spear, double open end (DOE), single open end (SOE), and custom configurations.
- Excellent Sealing: Gaskets made from NBR, EPDM, silicone, or Viton provide leak-free installation.
- Easy Retrofit: Designed to fit most standard filter housings with industry-standard dimensions.

Why Choose Our Skeleton Core Filter Cartridge?
Our cartridges are engineered to deliver consistent filtration efficiency while minimizing downtime. The skeleton core structure acts as a rigid backbone, allowing the pleated media to maintain its shape even under high flow surges. This design reduces the risk of media collapse and ensures a longer operational life compared to standard coreless filter cartridges. Additionally, the Mill Test Report provides full transparency of material quality, which is essential for industries requiring strict traceability, such as oil & gas, chemical processing, and pharmaceutical manufacturing.
We offer customization options for outer diameter, length, end cap type, gasket material, and filtration precision. Whether you need a standard 10-inch cartridge or a special 40-inch long unit, our factory can produce according to your specifications. All products are manufactured under standard compliant processes to meet the requirements of international filtration standards.
Trusted by clients in North America, Europe, Southeast Asia, and beyond. With an annual export value of US$5–10 million and a factory location in Hengshui, Hebei, we are well-positioned to provide competitive pricing and reliable logistics. Our shipping ports include Tianjin, Qingdao, Shanghai, and Foshan, ensuring fast delivery worldwide.
Frequently Asked Questions
-
Q1: What is a skeleton core filter cartridge?
A skeleton core filter cartridge features an inner and outer support cage (skeleton) that surrounds the filter media. This design provides superior mechanical strength, preventing the media from collapsing under high differential pressure or flow rate. -
Q2: Can I get a Mill Test Report for each batch?
Yes, we provide Mill Test Reports (MTRs) for the raw materials used in your order. The report includes chemical composition and mechanical properties of the stainless steel or other materials. Please request this during order placement. -
Q3: Are your cartridges compatible with standard filter housings?
Yes, our cartridges are manufactured to industry-standard dimensions (e.g., 2.5" OD, 10" length) and end cap configurations. They fit most commercial filter vessels from brands like Pall, Eaton, 3M, and others. -
Q4: What materials are available for the filter media?
We offer pleated polypropylene, stainless steel wire mesh, and depth filter media. The choice depends on your application, temperature, and chemical compatibility requirements. -
Q5: What is the maximum temperature this cartridge can handle?
For polypropylene (PP) versions, the maximum continuous operating temperature is 80°C (176°F). For stainless steel versions, it can go up to 200°C (392°F). Please confirm with our engineering team for extreme conditions. -
Q6: Do you offer custom lengths or diameters?
Absolutely. We can customize the outer diameter, length, end cap type, and even the core material. Minimum order quantities may apply for custom sizes. Contact us with your requirements. -
Q7: How do you ensure quality control?
Our factory is ISO 9001 certified (as per standard compliant manufacturing). Each cartridge undergoes visual inspection, dimensional checks, and a pressure test before packaging. We also perform random burst tests to ensure structural integrity. -
Q8: What is the typical lead time?
For standard cartridges, lead time is 15–20 working days. For custom orders, it may be 25–30 days depending on complexity. We also offer expedited shipping options.
