A cyclone with a tangential peripheral inlet and a central axial outlet is improved as to efficiency by inducting air between the inlet and the outlet. The inducted air is diverted by a baffle that temporarily separates it from the dust-laden inlet air, the baffle being arcuate in the same direction as the wall of the separation chamber, so that the inducted relatively dust-free air forms an inner layer and the dust-laden air forms an outer layer in the separation chamber. This promotes the separation of the dust on the inner side of the outer wall of the chamber and so facilitates separation of the dust from the air. A portion of the outlet air from which the dust has been separated can also be recycled in a stream disposed on the other side of the inducted ambient air.
