ABSTRACT:
This invention relates to an improvement in an evacuating apparatus attached to an air cleaner such as of an internal combustion engine as in connection with a farm tractor or an industrial engine operating in a dust laden environment where the contaminants drawn into the air cleaner are evacuated by the apparatus herein. The improvement consists in having a more positive evacuation of air transported contaminants in particulate form and evacuated with said contaminants are airborne particles of moisture carried with said contaminants. Comprising the apparatus of the invention is a small sized motor driving an impeller having vanes sweeping through a trough in the direction of exhaust, there being no return passage to the air cleaner.
