Abstract
A bladeless fan assembly includes a nozzle mounted on a base housing a device creating an air flow through the nozzle. The nozzle includes an interior passage receiving the air flow from the base and a mouth through which the air flow is emitted. The nozzle extends substantially orthogonally about an axis to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The depth of the base in the direction of the axis may be no more than twice the depth of the nozzle. The assembly produces an air current without requiring a bladed fan, that is, the air flow is created by a bladeless fan.
