The respirator sintered filter cartridge is a general-use filtration element widely used in the filtration industry, designed for purifying raw resources and enabling resource reuse. It is applicable in oil, air, and water filtration, removing small amounts of solid particles from liquids or gases, thus protecting equipment and ensuring clean air. As the fluid enters the cartridge fitted with a specific mesh, impurities are trapped while clean fluid flows out. The cartridge is suitable for weak acids, weak bases, and organic solvents, adopting a pleated deep filtration structure with a large filtration area, low pressure drop, high dirt-holding capacity, and long service life.
