Abstract
The fan casing has more than one outlet (A-D), preferably two or four outlets. The casing is of a substantially square-shaped outline and the outlets are situated in the corners thereof. The fan has an impeller (5) and comprises the casing, in which the length (a) of one side of the casing is less than 15% larger than the diameter (b) of the impeller.
