Ceiling Filter VF-600G is processed by the super long and anti-broken synthetic fiber, compounded with high quality water resin, the fiber density is increased layer by layer, filtering sponge is applied with solid adhesives and the surface is affixed with high intensity fiber glass nets, so VF can block and absorb the dust molecules more effectively, especially can absorb 96.8% of the dusts of 5um or above. VF does not only ensure more clean air and sufficient air flows, but also distribute air flows evenly in the whole working space. Applicable to air flow systems of auto painting equipment and pharmaceutical industries, and purified spaces with high demands for air purification and surface coating.
