Abstract

The support disc (10) has a bush (19) in its center and has e.g. 12 shovel-shaped blades (14) set at an angle round the periphery of the disc. There is a curved shroud (22) on either side of the disc, defining an axial air inlet for each side of the fan and radial outlets on each side of the support disc.
