Welcome to Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer established in 1998, specializing in wire mesh and filtration products. Our 304 Stainless Steel Skeleton-Supported Filter Cartridge is engineered for high-performance liquid filtration across a wide range of industries. With a filtration range from 0.5 to 100 microns, this cartridge combines robust construction with precise filtration to meet demanding process requirements. Backed by over 20 years of manufacturing expertise and an annual export value of US$5-10 million, we deliver reliable solutions to global markets including North America, Europe, Asia, and beyond.
Our skeleton-supported design features a durable 304 stainless steel inner core that provides excellent mechanical strength and resistance to high pressure and temperature. The pleated filter media — made of stainless steel mesh or fiber — offers a large filtration area, low pressure drop, and long service life. Whether you need to remove particles from water, chemicals, oils, or food-grade liquids, this cartridge is a cost-effective and reusable solution.
Key Features & Benefits
- 304 Stainless Steel Construction: Corrosion-resistant, suitable for aggressive fluids and high-temperature applications up to 250°C (482°F).
- Skeleton-Supported Design: Inner core prevents collapse under high differential pressure, ensuring consistent filtration performance.
- Wide Filtration Range (0.5-100 μm): Customizable to your specific particle size requirements — from fine polishing to coarse pre-filtration.
- High Dirt Holding Capacity: Pleated media increases surface area up to 3-5 times compared to standard depth filters, reducing replacement frequency.
- Reusable & Cleanable: Can be backwashed or chemically cleaned, offering long-term economy and reduced waste.
- Multiple End Cap Options: Available with open, closed, 222 O-ring, or 226 O-ring configurations for easy integration into existing housings.
- Low Pressure Drop: Optimized flow path minimizes energy consumption in pumping systems.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a skeleton-supported and a standard filter cartridge?
A: A skeleton-supported cartridge has an internal stainless steel core (perforated tube) that provides structural strength, preventing collapse under high pressure or during backwashing. Standard cartridges without a skeleton may deform or rupture under similar conditions.
Q2: Can this cartridge be cleaned and reused?
A: Yes, 304 stainless steel cartridges are fully cleanable. They can be backwashed with water or air, or chemically cleaned using appropriate solvents. This extends service life significantly compared to disposable cartridges.
Q3: What micron ratings are available for this filter?
A: We offer a wide range from 0.5 μm to 100 μm, including intermediate values such as 1, 5, 10, 20, 50, 80 μm. Custom ratings can be produced based on your specific needs.
Q4: Is the cartridge suitable for food and beverage applications?
A: Yes, the 304 stainless steel material is food-grade and can be used in direct contact with food products. It is also resistant to sterilization temperatures (e.g., steam cleaning).
Q5: What end cap options do you offer?
A: We provide open end (flat gasket), closed end, 222 O-ring, 226 O-ring, and other custom configurations. Please specify your housing requirements when ordering.
Q6: How long is the lead time for samples and bulk orders?
A: Sample orders usually ship within 5-7 working days. Bulk orders are typically 15-25 working days, depending on quantity and customization. We can expedite for urgent projects.
Q7: Can you provide a certificate of material or test report?
A: Yes, we can supply a material test certificate (MTC) for 304 stainless steel and a filtration efficiency test report upon request.
Q8: What is the maximum working temperature and pressure?
A: The cartridge can withstand continuous operating temperatures up to 250°C (482°F) and differential pressure up to 4.0 MPa (580 psi). For extreme conditions, please consult our engineering team.
