ABSTRACT:
An air cleaner comprising a housing, a plurality of tubular dust separator elements arranged in the housing for generally straight-through flow from one end of the housing to the other, the housing defining around the separator elements a dust collecting chamber. Each separator element has vanes for imparting spin to the air entering it and a circumferential exit of limited angular extent to the dust collecting chamber at a position where the air has substantial circumferential speed. The exits, the direction of spin, and baffles (if any) being arranged to avoid conflicting air flows in the chamber and to ensure that air movement in the chamber outside the exit is in the same direction as air movement within it. Preferably the separator elements impart left and right handed spin to air passing through them, with elements of opposite hand adjacent. In one arrangement the separator elements are arranged in rows with the elements of one row staggered with respect to those of the next, the elements of each row being of the same hand and the elements of adjacent rows of opposite hand, a baffle being disposed between the elements of each row.
