The inner cylinder forms with the housing a short cylindrical transfer chamber coaxial with, adjacent to, and axially outward of the separation chamber. A ring flange is disposed at the inner end of the inner cylinder along the inner ring of the annular separation chamber lying in a plane normal to the axis of the chambers. A dirt discharge slot is disposed in the side wall of the housing with one end of the slot substantially radially outward from the ring flange, the slot extending along a major portion of the axial length of the separation chamber. The ring flange extends radially outward from the inner end of the inner cylinder only a minor portion of the ditance from the inner cylinder to the side wall of the housing.
