Primary efficiency plate filter

The primary filter is a primary filtration device for air conditioning and air purification systems, mainly used to filter dust particles larger than 5 μ m. Divided into grades G1 to G4. Common styles include plate type, folding type, and bag type, as well as types such as activated carbon filters and high-temperature resistant coarse efficiency filters.

The primary filter adopts the principle of physical filtration, intercepting large particulate pollutants through filter material fibers. The outer frame material usually includes paper frame, aluminum frame, galvanized iron frame, etc., while the filter material includes non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, etc
