Blower with a roller-shaped blower impeller |
摘要 |
The fan blades (3) of a blower having a blower impeller (2) which is fashioned in the shape of a roller and into which air flows in axially from two sides, have a convex shape in the radial extent towards the middle of the fan blades (3). Thus a completely uniform velocity distribution is achieved in the outlet of the fan. <IMAGE>
