A fan assembly comprises a nozzle 14 having first (16, fig 1) and second (18) casing sections, at least one air inlet 28, at least one air outlet 30, 60, and an interior passage 46, 68 for conveying air from said at least one air inlet to said at least one air outlet. The nozzle defines a bore (20) through which air from outside the fan assembly is drawn by air emitted from the nozzle (induced). The nozzle is detachably mounted on a body (12), which comprises a flow generating means (fan) 90 for generating an air flow through the interior passage, and means 176 for treating the air flow before it enters the interior passage. The first casing section is detachable from the second casing section, with the first casing section defining, at least in part, the interior passage (fig 8). The treatment of the air comprises humidification by a piezoelectric transducer, heater, chiller, air purifier or an ionizer. Water for humidification may be sterilised using ultra violet (UV) radiation from a UV lamp (180, fig 16b) in a UV transparent tube (182). The first and second casings may be connected by snap fit connections 52. |
