A nozzle for a bladeless fan assembly comprises an interior passage 10 for receiving an air flow, and a mouth 12 through which the air flow is emitted, the mouth 12 being defined by facing surfaces of the nozzle, and spacer means 26 being provided for spacing apart the facing surfaces of the nozzle. The nozzle 1 defines an opening 2 through which air from outside the fan assembly is drawn by the air flow emitted from the mouth 12. The nozzle may be part of a fan assembly for creating an air current, the fan assembly further comprising a base on which the nozzle is mounted, the base further housing means for creating an air flow through the nozzle. The nozzle may be annular and extend about an axis. The spacer means 26 may comprise a plurality of spacers circumferentially spaced around the axis. A Coanda surface 14 and diffuser 46 may be located downstream of the mouth 12. |
