Initial folding air filter plate air filter element

The initial folding filter is a primary filtration device designed with V-shaped pleated filter material, specifically designed to intercept large particle pollutants such as dust, hair, fibers, etc. with a diameter of ≥ 5 μ m in the air. Its folding structure significantly increases the filtering area (up to 3-5 times that of ordinary plate type), improves dust holding capacity and reduces wind resistance. Combined with metal mesh and sealed outer frame, it combines stability and efficiency, and is widely used in air conditioning pre filtration, industrial dust removal, clean workshops and other scenarios, with convenient maintenance and cost-effectiveness.
