Abstract

So as to be able to employ, in an elongated flow duct (10), a centrifugal blower which is more powerful and produces less noise than a conventional axial blower, the centrifugal blower is disposed in such a way that the rotational axis (15) of its impeller (14) extends at an acute angle to the longitudinal axis of the flow duct (10). A casing wall (11), which contains the inlet port (12) of the blower, is designed as a partition in order to subdivide the flow duct (10) into a suction side and a discharge side. The inlet port (12) is approximately funnel-shaped, but with a radius of the funnel-shaped region which is greater towards the centre of the flow duct. It opens out into an inlet (13) assigned to the impeller (14). The impeller (14) is surrounded by a spiral-shaped chamber (18) which downstream in the direction of the longitudinal axis of the flow duct (10) opens out into an outlet (20). <IMAGE>
