As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our 304 Stainless Steel Pleated Filter Cartridge with a precision rating of 5 micron and a standard 2.5 inch outer diameter. This cartridge is engineered to deliver exceptional filtration performance across a wide range of industrial applications. Our factory, established in 1998, has consistently focused on quality and innovation, exporting to over 20 countries worldwide with an annual export value between US$5 million and US$10 million. Built from high-grade 304 stainless steel, this pleated filter cartridge offers superior durability, corrosion resistance, and reusability, making it a cost-effective solution for your filtration needs.
The pleated design significantly increases the filtration surface area, allowing for higher dirt holding capacity and longer service life compared to standard mesh or depth filters. Each cartridge is manufactured with strict quality control to ensure consistent micron retention and structural integrity under demanding conditions. Available in various lengths (10, 20, 30, 40 inches), our filter cartridges can be customized to fit most standard housings. The end caps are made of 304 stainless steel, and the sealing gaskets come in multiple materials (silicone, EPDM, or Viton) to suit different fluid compatibility requirements.
