Filter: consists of two layers glued together with holes fold Board composition, pose a number of v-type filter Chamber, in each of the filter Chamber, arrangement of holes creates a venturi effect or cyclone, forcing paint particles landed at the bottom of the filter Chamber, high efficiency of the separation from the venturi effect 

Filter efficiency: w-sided cardboard separators every filter Chamber with micro-settlement of space, depending on the injection product properties, separation rates of up to 98%, even if it is heavy and sticky products or jams
