A fan

A fan assembly for creating an air current is described. There is provided a bladeless fan assembly (100) comprising a nozzle (1) mounted on a base (16) housingmeans for creating an air flow through the nozzle (1). The nozzle (1) comprises an interior passage (10) for receiving the air flow from the base (16) and a mouth (12) through which the air flow is emitted. The nozzle (1) extends substantially orthogonally about an axis to define an opening (2) through which air from outside the fan assembly (100) is drawn by the air flow emitted from the mouth (12). The fan assembly (100) has a height extending from the end of the base (16) remote from the nozzle (1) to the end of the nozzle (1) remote from the base (16) and awidth perpendicular to the height both the height and the width being perpendicular to the axis so that width of the base (16) is no more than 75% the width of the nozzle (1). This arrangement creates a fan assembly with a compact structure.
