String Wound Cartridge Filter

A string-wound filter cartridge is a depth filter commonly used for removing sediment, dirt, rust, and other particulate contaminants from liquids. It consists of a tightly wound yarn or fiber (typically made from materials like polypropylene, cotton, or fiberglass) wrapped around a central core, which can be made of stainless steel or polypropylene.
