Detailed Product Description

The blower or exhauster increases the pressure of the aspirated gas by the
creation, in the peripheral torodial channel, of a series of vortexes caused by
the centrifugal thrust of the impeller.
While the impeller is rotating, the vanes force the gas forward and, because of the
centrifugal thrust, outwards, producing a helical motion. During this motion,
the gas is recompressed repeatedly with a consequent linear pressure increase along
the length of the channel.
