Stainless steel metal sintered mesh filter is generally divided into five-layer structure, which has four parts: protective layer, filter layer, separation layer and support layer. This kind of filter material has uniform and stable filtration accuracy but also has high strength and rigidity. It is an ideal filter material for occasions that require high compressive strength and uniform filter particle size. Because its filtration mechanism is surface filtration, and the mesh channel is smooth, it has excellent backwash regeneration performance and can be used repeatedly for a long time, especially suitable for continuous and automatic operation.
