The stainless steel metal sintered mesh filter cartridge uses a standard five-layer sintered mesh as the main filter medium, or can be customized as required. The standard five-layer sintered mesh is made by stacking five layers of stainless steel wire mesh and vacuum sintering, providing strong corrosion resistance, good permeability, high mechanical strength, ease of cleaning and backwashing, accurate filtration, hygienic filter material, and no mesh shedding. It is suitable for precise filtration of liquids and gases, capable of operating in high temperature, high pressure, and corrosive environments, and can be cleaned and reused for long service life.
