    Abstract: There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, a first air outlet for emitting an air flow and a second air outlet for emitting an air flow, the first and second air outlets together defining an aggregate air outlet of the nozzle, a single internal air passageway extending between the air inlet and the first and second air outlets, and a valve for controlling an air flow from the air inlet to the first and second air outlets. The valve comprises one or more valve members that are moveable to adjust the size of the first air outlet relative to the size of the second air outlet while keeping the size of the aggregate air outlet of the nozzle constant, and wherein the air outlets are oriented towards a convergent point.
