A cyclonic separation device is provided having improved pressure loss characteristics. A fluid supply conduit in flow communication with an inlet to a cyclone is located and configured to extend longitudinally through a central portion of the cyclone, whereby the sharp bending of the conduit may be reduced, thereby reducing pressure losses in the device, without unduly interfering with the cyclonic flow within the cyclone. The present invention may be adapted for use with cyclonic separation devices of all types, including single- and multi-stage cyclonic separators.
(b) a cyclone removable from the housing and having a bottom, a wall having an inner surface, a longitudinally extending axis and an outlet in communication with a source of suction;
(c) a fluid inlet to the at least one cyclone; and,
(d) a fluid supply conduit extending along the length of the cyclone from the bottom to the fluid inlet and forming a one-piece assembly therewith and communicating with a dirty air inlet and with fluid inlet, the fluid supply conduit removable with the cyclone from the housing.
