operation

The Regenerative Principle

In a regenerative blower, the compression space consists of a hollow,
circular ring between the tips of the impeller blades and the walls of the
housing. In operation, the rotating impeller draws in air from the inlet
port into the compression space and moves it radially outward to the
curved housing by centrifugal force.

The action is called “regenerative” because a certain amount of air
slips past each impeller blade during rotation and returns to the base
of a succeeding blade for reacceleration.

Because of this dynamic principle, regenerative blowers can generate
pressure and vacuum performance comparable to many multi-stage or
positive displacement blowers.
