Abstract
A bladeless fan assembly for creating an air current includes a nozzle mounted on a base housing a device for creating an air flow. The nozzle includes an interior passage for receiving the air flow and a mouth for emitting the air flow. The nozzle defines, and extends about, an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle also includes a heater for heating the air flow upstream of the mouth.
