ABSTRACT:
A high efficiency air precleaner has a base assembly, a hood, and a rotor assembly. The base assembly includes an inner circumferential wall and an outer circumferential wall, the inner circumferential wall defining an air outlet port. Angled web supports connect the outer circumferential wall to the inner circumferential wall and their arrangement forms air inlet ports that direct air upon the rotor assembly. The rotor assembly includes a rotatable hub that has arms extending outward therefrom, each of the arms including a radial first blade, an axial second blade descending at a right angle from the first blade, a paddle at the outer end of each arm, and a tab extending downwardly from the second blade adjacent the hub. The first blade extends from the edge of the second blade forwardly in a direction corresponding to the direction of rotation of the hub. Air incident upon the arms causes rotation of the hub, the arms flinging particulates outward. Air flowing over the back side of the second blade is unobstructed to enhance the efficiency of the precleaner. Particulates flung outward by the arms are discharged through the gap.
