A fan assembly includes a nozzle and a body on which the nozzle is mounted. The nozzle has a first air inlet, a first air outlet, and a first interior passage for conveying air from the first air inlet to the first air outlet. The nozzle also includes a second air inlet, a plurality of second air outlets, and a second interior passage for conveying air from the second air inlet to the second air outlets. The body generates a first air flow through the first interior passage and a second air flow through the second interior passage. A first air passageway conveys the first air flow to the first air inlet and a second air passageway conveys the second air flow to the second air inlet. One of the temperature, humidity, composition and electrical charge of the second air flow is changed before it is emitted from the nozzle.
