POWERED CONTAMINANT EVACUATOR ABSTRACT OF THE DISCLOSURE - This invention relates to an improvement in an apparatus attached to an air cleaner such as of an internal combustion engine as in connection with a farm tractor wherein the contaminants drawn into the air cleaner are evacuated to the atmosphere therefrom by said apparatus wherein the improve- ment consists in having the apparatus continuously operative, providing a positive evacuation of contaminants and comprising a relatively small sized motor driving an impeller which re- ceives contaminants from the air cleaner and evacuates or expells the same and embodies the use of a plurality of vanes whereby the engine associated with the air cleaner is prevented from drawing a reverse flow of air through the exhaust passage of the apparatus and the vanes serve-as closure means whereby there is no open passage through the apparatus to the cleaner and thus only a low powered impeller is required to expel the contaminants received. The air cleaner may be otherwise used than in connection with an internal combustion engine.
