A fan (10) for generating an air current includes a body (12) having an air inlet (14), and a nozzle (18) connected to the body. The nozzle includes an interior passage (42) for receiving an air flow from the body and an air outlet (20) from which the air flow is emitted from the fan. The interior passage extends about an opening or bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The body includes a duct (60) having an air inlet (62) and an air outlet (64), an impeller (70) located within the duct for drawing the air flow through the duct, and a motor for driving the impeller. A noise suppression cavity (166) is located beneath the air inlet of the duct. The cavity has an inlet (162) which is located beneath, and is preferably concentric with, the air inlet of the duct. |
