1. A nozzle for a fan assembly, the nozzle comprising:
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; and
a valve for controlling an air flow from the air inlet to the first and second air outlets,
wherein 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 first and second air outlets define a pair of slots provided on an elliptical face of the nozzle and are diametrically opposed to one another.
