Abstract
The present disclosure relates to an air cleaner for moving particles from an air stream. The air cleaner includes a housing defining a separation chamber at which at least some of the particles are removed from the air stream. The air cleaner includes an inlet passage for allowing the air stream to the separation chamber, an outlet passage for allowing the air stream to exit the separation chamber, and a plurality of vanes for causing the air stream to swirl as the air stream flows through the inlet passage and enters the separation chamber. The housing includes a side wall structure defining at least one discharge opening through which particles are discharged as the air stream swirls within the separation chamber.
