An air filter assembly including an outer housing having a peripheral wall defining a chamber having a central axis and first and second end walls extending generally transverse to the central axis, at least the first end wall being removable, said outer housing having an air inlet and an outlet adapted for connection to an air intake of an engine, filter element means interposed between said inlet and outlet and of a type to filter air passing from said inlet to said outlet without rotation of the filter element means, said outlet being defined by a tube, means to rotatably mount said tube on the first end wall of said outer housing about an axis substantially aligned with the central axis, said filter element means comprising an annular filter ring mounted for rotation with said tube and surrounding the axis of the tube, and means sealing said filter ring relative to the tube to cause air moving from said inlet to said outlet to pass through said filter element means, and motor means mounted on the exterior of the second end wall and having an output shaft extending into the interior of said chamber and substantially aligned with the axis of said tube, coupling means to releasably connect the filter ring to the output shaft, and means to selectively power the motor to thereby rotate said filter element means at a rate sufficient to cause dirt on the exterior of said annular filter ring to be dislodged by centrifugal force.
