Regenerative
blowers are sometimes called side channel blowers or ring compressors,
terms that refer to their physical construction. They can be direct or
belt driven. In direct drives, the impeller is mounted on an electric
motor shaft. The number, size, and angle of the blades on the impeller
determine pneumatic performance as well as the relationship between the
impeller and housing. Some blowers have rather flat performance curves
while others have steep ones.
