String Wound Filter Cartridges are manufactured by computer modeling process which optimizes the filter cartridges geometrically and maximizes the use of cartridge surface area by the diamondshaped depth filtration cones. Enhanced graded density design offers high flow rate, low pressure drop and improved dirt holding capacity. Several filter media are available in Tanvi’s SW series, playing more effective and efficient solutions in different applications and processes. ▶ Continuous strand winding process provides consistent performances of high dirt holding capacity, long service and high flow rate. ▶ Numerous filter media provide excellent chemical compatibility for different applications. ▶ No odor, no foaming and no media migration. ▶ Computer programming capability optimizes the filter cartridge geometrically and maximizes the use of surface area.
