A ramp outlet air precleaner has a base assembly, a dome shaped 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 the arrangement forms air inlet ports that direct air upon the rotor assembly. A ramp extends perpendicularly and axially from the outer circumferential wall and, starting at the top of the outer circumferential wall, the ramp surface winds around the outer circumferential wall in a spiral, terminating near the bottom of the outer circumferential wall below its starting point. The two ends of the ramp form the top and bottom of a particulate discharge port gap. The rotor assembly includes a hub that has arms extending outwardly therefrom. Air drawn into the inlet ports causes rotation of the hub and arms, with the arms flinging particulates outwardly toward the inner surface of the hood where they fall toward the discharge ramp. The spiral shape of the ramp surface creates significant velocity in the particulates, rapidly removing them out of the path of incoming air and discharging them through the discharge port.
