Abstract: A nozzle for a fan assembly is described. The nozzle includes a first duct through which a first airflow moves, the first duct having a first outlet for emitting the first airflow. The nozzle further includes a second duct through which a second airflow moves, the second duct having a second outlet for emitting the second airflow. The first and second outlets are arranged such that the first and second airflows collide to generate a combined airflow having a direction defined by the relative flow rates of the first and second airflows. The first duct then includes a portion moveable to vary the flow rate of the first airflow.
