Each group of blades has a plurality of spaced-apart blades which are generally parallel to the shaft and operatively connected thereto. There is a bearing support for the fan mounted on the housing near each end of the housing and between adjacent groups of blades. Each bearing support between adjacent groups of blades includes a U-shaped member extending about the convex surface of the housing. The shaft is rotatably mounted on the bearing supports.
