Motor-powered impeller for supply or exhaust.

MOTORIZED IMPELLER

This motor-powered impeller is suited for supply or exhaust uses where space is limited. The coupling of the speed-controllable PSC motor and backward-curved airfoil impeller minimizes space requirements and provides for vibration-free operation. Both motor and impeller are located directly in the airstream, where the impeller acts as a rotating heat sink, with heat dissipation and efficient motor cooling, company officials say. Near-zero speeds can be achieved using solid-state speed controls. The unit is available from stock in 115-volt and 230-volt single-phase models.
