A powered low restriction air precleaner device (36) and method for centrifugally ejecting heavier-than-air particulate debris from debris laden air for providing for a combustion engine air intake, and engine air cooling system, or a cab air intake system, for example. The device employs a fan (13) located in the device for drawin debris laden air into the air precleaner device. The debris laden air spun in the air precleaner device to form a rotating flow pattern that stratifies the debris laden air with the most massive particles of debris in the outermost orbits of the rotating flow pattern of debris laden air. Debris from the rotating flow pattern is ejected from the device for cleaning the air, which is flowed to an air outlet (32) of the device for supplying the cleaned air. |
