The stainless steel five-layer sintered mesh filter cartridge is made by vacuum sintering multiple layers of stainless steel mesh into a filtration material with high mechanical strength and overall rigidity. The mesh layers have staggered pore sizes forming a uniform and stable structure. Compared to ordinary wire mesh, it offers higher strength, rigidity, and pore stability, allowing optimal matching of void size, permeability, and strength. It has excellent filtration accuracy, wear resistance, heat resistance, and processability, with overall performance superior to other types of filtration materials. Suitable for precision water filtration in cement, mining, metallurgy, chemical, automotive, electronics, and pharmaceutical industries.
