Abstract

The present invention relates to a fan housing for feeding air via an outlet (14) to a ventilation system. The fan housing comprises a radial impeller (16) rotatably mounted to a shaft which wheel has at least one centrally arranged inlet (17) and a number of impeller blades (18). Furthermore, there is a wall (20) being substantially parallel to the rotational axis which wall is curved with a monotonous increasing radius in relation to said shaft, between a first end edge (21) at a certain distance from said impeller and a second end edge (22) at a larger distance from said impeller. An imagined, straight line (23) between the two end edges (21, 22) extends through the impeller (16). <IMAGE>
