HeyiPrimary efficiency plate filterUsing synthetic fibers with gradually increasing density and strong toughness, and adopting seamless fusion technology, it has good air tightness and bonding strength, which will not cause air leakage or rupture when the wind pressure is high. The bag also adopts a unique support design to ensure its stability and excellent filtration effect; The filter material itself does not contain organic silicon and is particularly suitable for use in paint workshops. This device is generally suitable for front-end filtration and air conditioning applications in automotive paint workshops in the painting industry, such as air conditioning systems in commercial buildings, warehouses, schools, laboratories, and other places.
