A powered air cleaning system has a flow path extending through the system from an inlet to an outlet. A motor-driven fan is located along the flow path to draw particulate debris laden air into the inlet and rotate it about an axis to form a rotating flow that stratifies the debris laden air with the heaviest particles in the outermost orbits of the rotating flow. An ejector port ejects particulate debris laden air from the stratified rotating flow in the system. At least one de-swirl component located within the rotating flow aerodynamically redirects clean air from the innermost orbits of the stratified rotating flow toward the outlet to provide a positive airflow pressure out of the outlet. The system has a variable speed fan motor and an integrated controller for adjusting the speed of the motor and thereby the flow rate of clean air through the outlet of the system. The controller receives a signal that is a function of airflow requirements of a device supplied with clean air by the system. The system can be mounted above or below a hood housing an engine to be supplied with clean air.
