A fan assembly for creating an air current is described. The fan assembly includes a nozzle mounted on a base housing a device for creating an air flow through the nozzle. The nozzle includes an interior passage for receiving the air flow from the base, a mouth through which the air flow is emitted, the mouth being defined by facing surfaces of the nozzle, and spacers for spacing apart the facing surfaces of the nozzle. 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 fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan. The spacers can provide for a reliable, reproducible nozzle of the fan assembly and performance of the fan assembly.
A bladeless fan assembly for creating an air current, the fan assembly comprising a nozzle mounted on a base for creating an air flow through the nozzle, the nozzle comprising an interior passage for receiving the air flow from the base, a mouth through which the air flow is emitted, the mouth being defined by first and second facing surfaces of the nozzle, and a plurality of spacers for spacing apart the facing surfaces of the nozzle, the nozzle defining an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth, wherein the spacers are integral with the first facing surface, one of the facing surfaces of the nozzle is biased towards the other of the facing surfaces so that the spacers contact the second facing surface to space apart the facing surfaces, and the biasing occurs independently of the spacers.
