Abstract
Abstract The invention provides cyclonic separating apparatus comprising an upstream cyclone unit and a downstream cyclone unit, the upstream cyclone unit including at least one cyclone having a first end and a second end, and the downstream cyclone unit including at least one cyclone having a first end and a second end. The upstream and downstream cyclone units of the cyclonic separation apparatus are arranged relative to one another so that the orientation of at least one cyclone of the downstream cyclone unit is substantially inverted with respect to the orientation of at least one cyclone of the upstream cyclone unit. The arrangement provides an apparatus in which good separation efficiency is achieved as well as low pressure drop across the apparatus as a whole.
