String Wound Cartridge A string-wound cartridge is a type of filtration device commonly used for removing sediment, rust, sand, and other particulate contaminants from liquids. It is constructed by tightly winding a continuous strand of fibrous material, such as cotton, polypropylene, or glass fiber, around a perforated core. This design creates a gradient density filter, meaning the outer layers capture larger particles while the inner layers trap finer contaminants, providing a high dirt-holding capacity and efficient filtration. String-wound cartridges are widely used in industries such as water treatment, chemical processing, and food and beverage production, where they help protect downstream equipment and improve the quality of processed liquids. Their durability, chemical resistance, and ability to handle high flow rates make them a versatile and cost-effective solution for various filtration needs.
