Cyclone separator

The cyclonic separator to separate particles from an air stream has a first stage with at least one centrifugal separator with a guide vane apparatus (12) to create a swirling movement of the fluid. The first stage is connected directly to a second stage which has a cylindrical housing (13) and in the region of the fluid outlet a dust discharge, and a concentrically installed truncated cone shaped center pipe (16). The second stage extends by its inlet side (18) at least partially into the first stage.
