The fan machine with at least one stator and a downstream rotor, for gas or liquid flows, has fixed vanes (1) with a rounded radius (12) at the stator and the rotor with a number of vanes is on a rotating shaft. A housing contains the flow through the assembly. A fluid flow take-off opening, to give secondary flows at the walls of the main flow path, has a convex curvature against the suction side (6) of the vane. The opening has an angled or rounded edge with an edge normal forming an included angle (alpha ) of 70-250[deg] with the profile chord (7) of the vane. The vane assembly has a pressure side (10), with a position field (11) for the take-off opening. |
