The stainless steel multi-layer sintered mesh filter element primarily uses a standard five-layer sintered mesh as the main filter medium, customizable if needed. The five-layer sintered mesh is composed of multiple stainless steel wire meshes stacked and vacuum sintered into an integrated structure, offering both high strength and stability. This filter element features excellent corrosion resistance, good permeability, high mechanical strength, ease of cleaning (including backwashing), accurate and stable filtration precision, hygienic and clean material, and no wire shedding. The filtration area is large (5–10 times that of ordinary cylindrical filter elements) with a broad filtration precision range (1–300 μm). In industries like chemical, petrochemical, and steel, it can be reused after cleaning, with a service life of at least 1 year in chemical environments and 2 years in water treatment environments if maintained properly; high acidity/alkalinity or chloride content can reduce service life. Widely used in filtration of polymer melt, oil-water separation, high-temperature gas, pharmaceuticals, and similar mediums.
