A hand dryer (10) of the type used in public restrooms is disclose which includes an internal gas path at least partially defined between an air inlet (23) through which air flows into the hand dryer and an outlet opening (38) at a downstream end thereof through which air flows out of the hand dryer, and a compressor (28) driven by a motor (30) for drawing air into the air inlet, compressing the air, and feeding the air to the outlet opening. A variable-flow exhaust nozzle (18) is located at the downstream end of the hand dryer, the variable exhaust nozzle defining the outlet opening (38) at an exit thereof, the variable exhaust nozzle (18) being operable to vary the size of the outlet opening (38) in order to control one or more properties of the airflow exiting the outlet opening. |
