The stainless steel pleated powder sintered filter cartridge is made from a standard five-layer sintered mesh, composed of five layers of stainless steel wire mesh stacked and vacuum sintered, incorporating a protection layer, precision control layer, dispersion layer, and multiple reinforcing layers. It offers excellent corrosion resistance, permeability, high mechanical and compressive strength, stable filtration precision, easy cleaning (supports backwashing), hygienic filter media, and no wire shedding. The filtration precision ranges from 2–200 μm, and it performs stably between −200 °C and 650 °C, suitable for precision filtration of liquids and gases, widely used in petrochemical, metallurgy, and chemical industries. Supports standard interfaces (222, 220, 226), quick connect, threaded, flange, tie rod, and custom connections. Filter materials available: stainless steel (304/316/316L/304L), Hastelloy (C276/C22), high alloy (904L/2205/2507), and duplex steel.
