Abstract: A fan assembly comprising an airflow generator and a nozzle. The nozzle comprising a body defining an air inlet to receive generated airflow, an air outlet section, and a switching member. The switching member switches between a first position, delivering only a first airflow to the outlet, and a second position, delivering both first and second airflows. The air outlet section comprises a first inlet for the first airflow, a second inlet for the second airflow, an air outlet for emitting airflow from the fan assembly, and pathways between the first inlet and the air outlet. In the first position, the first airflow travels along the first pathway and is emitted in a first outlet direction. In the second position, the second airflow interacts with the first, redirecting it along the second pathway, and emitting it in a second, different outlet direction.
