ABSTRACT:
An air precleaner and method for centrifugally ejecting heavier-than-air particulate debris from an air stream utilizes a circular separator chamber formed with a toroidal dome for smooth airflow transition of the vortex airflow moving through the separator chamber in a cyclonic pattern upwardly from an inlet in a base of the precleaner past a debris ejection duct where it is folded over by the toroidal dome for whirlpooling down to an outlet in the base radially inwardly of and through the upwardly moving vortex airflow. The area for the airflow in the separator chamber progressively decreases linearly to increase the speed of the airflow in the chamber. A particle accelerator assembly includes a plurality of appendages that arc back from a central hub in a swept-back attitude relative to a direction of the vortex airflow. The particle accelerator assembly is rotatably powered at a speed in excess of the speed of the incoming vortex airflow for increasing the speed thereof in interaction of a portion of the appendages with the higher speed outgoing airflow. The air precleaner, which can be used for internal combustion engines, for example, dramatically improves the removal of heavier-than-air particles across a broad spectrum of intake air demand. It maximizes the use of centrifugal force while minimizing airflow restriction, offering a flat performance curve over the entire airflow range.
