Our 20-inch stainless steel filter cartridge is manufactured using advanced welding and finishing techniques. The pleated version offers up to 5 times more surface area than standard mesh, translating to higher flow rates and longer service intervals. For applications requiring high temperature or high pressure, we recommend using metal gaskets and inspecting the cartridge regularly. The cartridge is also compatible with automatic backwashing systems when ordered with a perforated core.
We understand that each project has unique requirements. That is why we offer customizable options including different lengths (10, 30, 40 inches), special alloys (316L, 904L), and filtration ratings. Our engineering team will work with you to ensure the cartridge meets your precise specifications. With over 25 years of manufacturing experience, we have supplied millions of filter cartridges to clients worldwide, including North America, Europe, Southeast Asia, and Africa.
