Heyi'sPrimary filter screenUsing synthetic fibers with gradually increasing density and strong toughness, made by 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.
