Abstract: There is provided a fan assembly comprising a motor-driven impeller for creating an airflow and a nozzle comprising a first air outlet. The nozzle defines a bore through which air from outside the fan assembly is drawn by any portion of the airflow that is emitted from the first outlet and which combines with the airflow emitted from the first air outlet to produce an amplified airflow. The fan assembly further comprises a second air outlet arranged such that any portion of the airflow that is emitted from the second air outlet does not draw air through the bore defined by the nozzle thereby producing a non-amplified airflow.
