"A Fan"

Abstract: A fan assembly for creating an air current is described. The fan assembly (100) comprises a nozzle (1) mounted on a base (16) housing means 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), a mouth (12) through which the airflow is emitted, the mouth (12) being defined by facing surfaces of the nozzle (1), and spacer means (26) for spacing apart the facing surfaces of the nozzle (1). 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 provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan. The spacer means provide for a reliable, reproducible nozzle of the fan assembly and performance of the fan assembly.
