Abstract

The fan has an induction aperture (28) for its first induction cavity (A1). The second induction cavity (A2) faces the surrounding wall region (19) directly along the scoop crown. There is at least one flow element in the casing outside the running wheel, which can be adjusted by a setting device so that the characteristics of the fan can be altered.
