  • Engine air cleaner
    Patent number: 4303423
    Abstract: An engine air cleaner comprising a cylindrical housing containing an annu perforate cleaning medium and a set of pre-cleaning baffles in the housing space surrounding the cleaning medium. The baffles maintain the dust-laden gas in a swirling condition, thereby centrifugally forcing heavy dust particles away from the cleaning medium surface. A scavenger fan removes heavy dust particles from the housing before such particles can contact the cleaning medium.
