As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our 316L Stainless Steel Tapered Filter Cartridge 20 Micron – a precision-engineered solution designed for demanding liquid filtration applications. With an annual export value of US$5 million to US$10 million and serving markets across North America, South America, Europe, and Asia, we combine decades of wire mesh expertise with modern manufacturing to deliver cartridges that balance high flow rates, deep filtration, and long service life. Each cartridge is ISO 9001 compliant and comes with a gasket for secure sealing, offering you a reliable, cost-effective filtration component.
Our tapered filter cartridge is crafted from premium 316L stainless steel, which provides superior corrosion resistance against acids, alkalis, and chlorides, making it ideal for harsh environments such as seawater desalination, petrochemical refining, and pharmaceutical processing. The 20 micron absolute rating ensures consistent removal of particles while maintaining low pressure drop. The tapered design (progressive density) allows for maximum dirt-holding capacity and extended service intervals – a key advantage over traditional non-tapered cartridges.
Key Features & Technical Specifications
| Material | 316L Stainless Steel (AISI 316L, low carbon) |
| Micron Rating | 20 Micron (absolute – 99.9% efficiency at 20µm) |
| Gasket | Included (EPDM, Buna-N, or Silicone – customizable) |
| Shape | Tapered (progressive density from outer to inner layer) |
| Length Options | 10", 20", 30", 40" (custom lengths available upon request) |
| Operating Temperature | -20°C to 120°C (with gasket) / up to 200°C without gasket |
| Operating Pressure | Up to 0.5 MPa (differential) – higher options available |
| Surface Finish | Bright annealed or matte; smooth inner surface for easy cleaning |
Product Advantages & Customer Benefits
- Enhanced Filtration Area: The tapered design increases the effective surface area compared to cylindrical cartridges of the same outer diameter, reducing velocity and allowing finer particles to be captured deeper inside the media.
- Longer Service Life: Progressive density means larger particles are trapped in the outer layers while smaller particles are captured near the core – you get up to 2-3 times the dirt-holding capacity of standard cartridges, reducing replacement frequency.
- Corrosion & Chemical Resistance: 316L stainless steel withstands aggressive fluids and high chloride environments, making it suitable for seawater, brine, acids, and alkaline solutions.
- Secure Gasket Seal: The included gasket (standard EPDM or optional materials) eliminates bypass leakage, ensuring every drop of fluid passes through the filter media – critical for applications requiring absolute filtration.
- ISO 9001 Quality Assurance: Our entire manufacturing process – from raw material inspection to final testing – is carried out under ISO 9001:2015 certified quality management system. Each cartridge is individually checked for dimensional accuracy and weld integrity.
- Flexible Customization: We offer custom lengths, gasket materials, end cap configurations, and outer diameters to match your existing housing. Contact us for a tailored solution.
Beyond the technical specifications, our 316L stainless steel tapered filter cartridge delivers tangible operational benefits: reduced downtime due to less frequent cartridge changes, lower energy consumption from a lower pressure drop, and consistent product quality thanks to reliable 20 micron removal. Whether you are filtering cooling water, process chemicals, or food-grade liquids, this cartridge is engineered to perform.
Frequently Asked Questions (FAQ)
- What is the exact micron rating of this cartridge? – The cartridge has an absolute rating of 20 micron, meaning it will remove 99.9% of particles ≥20 µm. The nominal rating is finer (around 10-15 µm) due to the depth filtration effect.
- Can I use this cartridge for high-temperature fluids? – Yes, with the appropriate gasket. With EPDM gasket, maximum continuous temperature is 120°C; without gasket, the stainless steel media can withstand up to 200°C. Silicone or Viton gaskets are available for higher temperatures.
- Is the gasket replaceable? – The gasket is bonded to the end cap but can be replaced if needed. We recommend ordering spare gaskets or specifying your preferred material when ordering.
- What is the typical flow rate for a 20-inch cartridge? – Flow rate depends on fluid viscosity and pressure drop. For clean water at 0.1 bar differential, a 20-inch cartridge can handle approximately 5-10 m³/h. Contact us for a detailed sizing calculation.
- Can I get a sample before bulk order? – Yes, we offer sample cartridges (1-2 pieces) for testing. Shipping costs are negotiable. Sample orders are typically processed within 5-7 days.
- Does the cartridge come with a certificate of analysis? – Yes, we can provide a material test certificate (MTC) for the 316L stainless steel and a dimensional inspection report for each batch. This is part of our ISO 9001 compliance.
- What is the minimum order quantity (MOQ)? – For standard lengths (10-40 inches), MOQ is 50 pieces. For custom lengths, MOQ may be lower depending on the design. We also offer stock for small quantities for urgent needs.
- How do I clean this cartridge if it becomes clogged? – Due to the sintered or wire-wound nature, backwashing or ultrasonic cleaning can restore some capacity. However, these cartridges are designed for single-use (disposable) – replacement is more cost-effective than cleaning. We can provide a cleaning guide if needed.
