KETCO SPIRALFLOW is a String Wound Filter Cartridge designed for reliable industrial liquid filtration with high dirt-holding capacity and low pressure drop. Its innovative diamond-pattern winding helps capture larger particles on the outer layers and finer contaminants deeper inside, extending service life by up to 30–50% compared to traditional string wound designs. Available in polypropylene, bleached cotton, and glass fiber media, it supports a wide micron range and multiple end cap options for easy installation in standard filter housings.
