CSW Series Bleached Cotton String Wound Cartridge Filters provide high dirt holding capacity for particles whose micron diameters are common in liquid processing industries. Bleached cotton wound cartridges are made of bleached cotton wound yarn and stainless steel central or pp core, with double open end (DOE) or types of end cap, such as 222/fin,226/flat etc.. Cotton string wound cartridges are designed as honeycomb-shap to ensure no short fibers break away. In addition, bleached cotton string wound cartridges provide high flow rate, good chemical resistance, excellent efficiency filtration and long service life. Cotton string wound filters are widely used in industrial oil/water separation, petrochemical process, power plant water treatment and many other crucial industrial fields.
