Beschreibung
Zusammenfassung:	A nozzle 14 for a fan assembly comprises an interior passage for receiving an airflow and a mouth for emitting an airflow, and a plurality of guide vanes 120 located within the interior passage, each directing a portion of the airflow towards the mouth, the nozzle 14 defining an opening through which air from outside the fan assembly is drawn by the airflow emitted from the mouth. A bladeless fan assembly may comprise the nozzle 14 and a means for creating the airflow. The vanes 120 may be shaped to change the direction of the airflow by around 90°, and the mouth may be shaped so as to substantially reverse the flow direction of each portion of airflow. The vanes 120 may be located on an internal surface of an inner casing section of the nozzle 14.
