摘要

The ventilator is a radial ventilator (5) with housing (4) mountable on a window frame (2). The ventilator can be fitted in the housing in at least two assembly positions so that a suction side can be connected with the one opening (6,7) of the housing or with the other opening depending on the assembly position. An intermediate wall of the ventilator provided to separate the suction side from the pressure side separates the openings of the housing from each other in the assembled state.
