ABSTRACT This disclosure is directed to an air cleaner for use with internal combustion engines that cleans the air by separating particulate matter prior to filtration. The air cleaner consists of a cylindrical casing having an axial inlet for uncleaned air, a first outlet for the separated particulate matter and a second outlet for the cleaned air. A separator taking the form of a truncated cone converges from the inlet to the first outlet, and includes a plurality of louvers that define a flow path to the filter and clean air outlet. By reason of its inertia, particulate matter in the incoming uncleaned air is incapable of changing its direction to flow through the louvers, and it continues toward the first outlet for discharge. The filter is also conically shaped and con- centric with the separator, formed from inner and outer perforate shells with a pleated filter sandwiched therebetween. The separator and filter are preferably formed as a single unit that is replaceable through removal of an end cap of a casing. The apparatus may also include a high pressure nozzle to assist in removal of the separated particulate matter from the unit.
