ABSTRACT:
The fan comprises a volute housing (10) in which is disposed a ventilation wheel (11) connected to a driving motor (12). The wheel has a series of vanes (13) extending in a direction roughly parallel to the axis of rotation (X--X) of the wheel from a bowl (14) connecting the vanes to the driving motor to an edge portion (15) of an air intake (16) defining with the bowl a space for a fluid stream. The confronting surfaces of the bowl and the edge portion of the air intake, at least to the inner edges of the vanes, are generated by rotation of parallel sections of curves about the axis of rotation (X--X).
