304 stainless steel security filter, the filter element can be PP meltblown, wire wound and folded, the flow rate is 1 ton to 150 tons, the length of the filter element is 10 inches 20 inches 30 inches 40 inches, and the accuracy is 1-5 microns. 1. Overview: Precision filters, also known as security filters, use a new type of polypropylene melt blown filter element (PP cotton filter element) or wire wound filter element as the filter material. According to the filter pore size of different precision, particles of different particle sizes are intercepted. So as to achieve the purpose of filtering.　　　　 2. Scope of application: Precision filters are widely used in the pretreatment processes of food, medicine, electronics, chemistry, petroleum and other industries. The precision filter has the characteristics of high filtration accuracy, small filtration resistance, large water flux, acid and alkali resistance, etc., and low price and low operating cost. 3. Technical parameters of 3-core 20-inch precision filter: Size: 170MM diameter, 650MM height Working pressure: 0.1MPa-0.6MPa Working temperature: 5℃-40℃ Filter element interface: flat pressure type, plug-in filter accuracy: 1μm-100μm (Commonly used precision is 1 micron and 5 micron) Number of filter elements: 3 elements Filter element length: 20 inches (508mm) Single flow rate: 2-3 tons/hour Cylinder material: 304 Water inlet and outlet: DN25 internal thread Filter media: tap water And underground well water with better water quality.
