Abstract
A bladeless fan assembly includes a nozzle mounted on a base housing a motor and an impeller driven by the motor for creating an air flow. The nozzle includes an interior passage for receiving the air flow, a mouth for emitting the air flow, and a plurality of stationary guide vanes located within the interior passage and each for directing a portion of the air flow towards the mouth. The nozzle defines an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth.
