String wound filters using cotton or polyester string, stainless steel core, usually for cooking oil filtration. STRUCTURE String wound filter cartridge consists of multi-hole frames wound closely with textile fibers. Diverse kinds of filtering precision can be realized by controlling the winding density. As the outer bore diameter is larger than the inner one, the filter cartridges have a good deep-level filtering capability. JP cotton & PE series has straight multi-hole from surface to the inner core, which performance a maximum dirt holding capacity and lowest pressure drop. FEATURES 1 Through holes create real depth filtration 2 Higherflow and lower pressure loss 3 High dirt holding capacity and long service life. 4 Cotton or polyester yarn and ss core which bare higher temperature MAIN TECHICAL SPECIFICATION 1 Dimension: Outer diameter:63�±1mm, Inner diameter: 28mm or 30mm 2 Maximum operating Pressure: 0.5MPa 3 Temperature: Cotton 150 degrees, PE 130 degrees. TYPICAL APPLICATIONS 1 Cooking oil, palm oil, soy sauce (cotton or PE) 2 Organic solvents (cotton only) 3 Petroleum product (cotton only) 4 Other applications
