Abstract
A single stage axial blower design provides a series of blowers producing a wide range of delivery flow rates even though they have the same outer dimension, drive speed and guide wheel. This is achieved by a structural combination which includes a stationary guide vane wheel (5) of fixed design and impellers (8) which have varying hub diameters (9, 9a, 9b) but the same outer diameter. Thus, a series of blowers having the same external dimensions and the same stationary guide vane structure can be used with a series of air-cooled internal combustion engines which differ from one another in number of cylinders and related cooling requirements.
