Abstract (en)
A vortex finder (F) for a cyclonic separator, the vortex finder comprising a plurality of stationary vanes (V) having a round convex front end around which incoming air (A) is guided into the vortex finder (F), a cross-section of the vanes (V) having only one sharp edge (E) where air separates from the vane (V) inside of the vortex finder (F). Preferably, a mean line (M) of the cross-section of the vanes (V) does not cross a chord line (C) in an upstream half of the cross-section. A vacuum cleaner comprising a cyclonic separator preferably has such a vortex finder (F).
