Abstract
A fan includes a central hub defining an inlet, a motor positioned within the central hub, and an impeller positioned within the central hub. The impeller is operable to be rotated by the motor to generate air movement. The fan also includes a nozzle defining a channel that receives the airflow from the central hub. The nozzle also defines an outlet in communication with the channel to direct air out of the nozzle. The fan further includes a plurality of conduits connecting the nozzle to the central hub to direct air from the central hub to the channel and through the outlet of the nozzle. The nozzle defines a projection aligned with each conduit to divide air movement through the nozzle.
