A particulate separator (1) of the concurrent flow type includes an inner cylinder (10) mounted concentrically within a tapered conical outer cylinder (11) which is closed at the outer return end. A fan unit (12) is secured within the return end of the outer cylinder (11) to draw air inwardly through the inner cylinder (10), impart a centrifugal force thereon and imparting a tangential spin to the air moving outwardly and then rearwardly and back through the outer conical cylinder (11). The particulate matter within the fluid moves outwardly to the periphery of the outer cylinder (11) as a result of centrifugal forces. The tangential spin imparted to the air cause the air to move in spiral return path with the conical cylinder (11) establishing a decreasing cross section. The discharge end of the tapered cylinder (11) includes a main air discharge outlet encircling the inlet cylinder (10) for discharge of the clean air and an outer annular skimmer (13) including an inner parting wall (32) separating the outer layer of air adjacent the outer cylinder annular opening for separate removal of the particulate air stream adjacent to the periphery of the cylinder (11). |
