FOW Series High Flow String Wound Cartridges


FOW Series High Flow String Wound Cartridges are made 100% pure high-quality polypropylene, FDA-approved. It's constructed by thermal welding technology with large diameter, which could greatly save water treatment plant footprint and reduce filter change-out cost. All polypropylene components construction provides excellent chemical resistance to acids, bases, salts and many organic solvents in a board range of processes.

FOW series high flow wound cartridges have an inner core, which significantly increases their resistance to pressure spike, and also prevents the release of fibers to the filtered liquid. The wound cartridge filters are equipped with a special connector: holder for easy installation of the cartridges in the housing and a sealing end which prevents the ingress of contaminant particles into the liquid. High flow wound cartridges are ideal for water treatment application such RO pre-treatment, food and beverage processing, fine chemicals and coating, etc.
