Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial filtration solutions, exporting over US$5 million to US$10 million annually to markets across North America, Europe, Southeast Asia, Africa, and beyond. Our Polypropylene Skeleton Core Filter Cartridge (2.5" OD x 40" Length, 5 Micron Nominal) is engineered to deliver consistent, high-performance filtration for demanding applications. With a robust polypropylene skeleton core and premium melt-blown media, this cartridge combines excellent dirt-holding capacity with low pressure drop, making it an ideal choice for pre-filtration, process water, and chemical processing.
Whether you are treating municipal water, protecting reverse osmosis membranes, or filtering industrial fluids, our cartridge ensures reliable particle removal down to 5 microns nominal. The skeleton core provides enhanced structural integrity, preventing collapse under high flow rates or varying pressure conditions. Trusted by clients worldwide, this product reflects our commitment to quality, precision, and customer satisfaction.
Key Features & Benefits
- High-Purity Polypropylene Construction: 100% polypropylene media and core – no binders, adhesives, or surfactants, minimizing extractables and ensuring chemical compatibility with a wide range of fluids (acids, bases, solvents).
- Deep Gradient Density Structure: The outer layers capture larger particles while inner layers trap finer contaminants, offering high dirt-holding capacity and extended service life.
- Rigid Skeleton Core: The inner polypropylene skeleton provides mechanical strength, preventing collapse under high differential pressure (up to 4.2 bar / 60 psi at 25°C).
- Low Pressure Drop: Optimized fiber distribution ensures low initial resistance, reducing energy consumption in pumping systems.
- High Flow Rates: Designed for efficient flow – typical flow rate of 1.0–2.0 GPM per 10" length (depending on fluid viscosity).
- Versatile End Cap Options: Available with open end, double open end, 222/226 O-ring, or flat gasket configurations – customizable to fit most filter housings.
- Thermal Stability: Continuous operating temperature up to 80°C (176°F), with intermittent peaks up to 90°C (194°F).
- FDA-Compliant Materials: All polypropylene components meet FDA regulations for food contact (CFR 21), suitable for potable water and food & beverage applications.

Frequently Asked Questions (FAQ)
-
Q: What fluids can this cartridge filter?
A: The polypropylene skeleton core cartridge is compatible with water, acids, alkalis, solvents, and many industrial chemicals. It is not recommended for strong oxidizing agents or hydrocarbons above 60°C. Always verify compatibility with your specific fluid. -
Q: Can I get a different micron rating or length?
A: Yes, we offer custom micron ratings from 1 to 100 microns and lengths from 10" to 50". Please contact us with your requirements. -
Q: What is the typical replacement interval?
A: Service life depends on influent quality and flow rate. Typically, when differential pressure reaches 20–25 psi (1.4–1.7 bar), or when effluent quality deteriorates, it is time to replace. For most applications, replacement is every 1–3 months. -
Q: Is this cartridge suitable for food-grade applications?
A: Yes, the polypropylene materials are FDA compliant for food contact. We can provide a certificate of compliance upon request. -
Q: What end cap configurations are available?
A: Standard options include open end (with or without gasket), double open end, 222 O-ring, and 226 O-ring. Custom configurations are possible – please specify your housing type. -
Q: Can this cartridge withstand high flow rates?
A: Yes, the skeleton core provides excellent structural integrity. For a 40" cartridge, a maximum flow rate of 8 GPM (water) is recommended. Higher flow rates may require larger diameter cartridges or multiple units. -
Q: Do you offer samples before bulk order?
A: Yes, we provide samples for testing. Please contact us to discuss sample quantity and shipping costs. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 50 pieces for standard sizes, but we can discuss smaller quantities for new customers. Contact us for details.
