Abstract

Die Ventilatoreinheit hat einen Ventilator (3) und einen ihm zugeordneten Diffusor (4). Zur Erhöhung des statischen Wirkungsgrades des Ventilators und zur Verringerung des Ventilatorgeräusches ist an den Diffusor (4) ein Diffusoraufsatz (22) so angeschlossen, dass die Innenwand (24) des Diffusoraufsatzes (22) eine stetige Fortsetzung der Innenwand (25) des Diffusors (4) bildet. Der Diffusor (4) und der Diffusoraufsatz (22) sind jeweils mit einer Schnittstelle (20, 23) versehen, mittels denen die beiden Teile verbunden werden können.

Figure imgaf001
The fan unit has a fan (3) and an associated diffuser (4). To increase the static efficiency of the fan and to reduce the fan noise to the diffuser (4) a diffuser attachment (22) is connected so that the inner wall (24) of the diffuser attachment (22) is a continuous continuation of the inner wall (25) of the diffuser (4 ). The diffuser (4) and the diffuser attachment (22) are each provided with an interface (20, 23) by means of which the two parts can be connected.
