The main filter material of the five-layer stainless steel sintered wire mesh filter element is a standard five-layer stainless steel sintered mesh. Standard five-layer stainless steel sintering is made by superimposing five layers of stainless steel wire mesh and vacuum sintering. The filter element made of it has the characteristics of strong corrosion resistance, good permeability, high strength, easy cleaning and reverse cleaning, high filtration accuracy, hygienic and clean filter material, and no wire mesh falling off.
