It is achieved a smooth running of the fan, making this and thus the overall air cleaning device are designed to last. In addition, operating noise of the air purification device by the quiet running vermin changed. The replacement of the fan wheel, possibly together with the drip pan and designed as a flow rectifier cover, after removal for cleaning is also facilitated, since in each rotational position of the motor shaft and the fan to each other possible.
