Abstract

A fan for generating an air current includes a body 12 having an air inlet14, and a nozzle 18 connected to the body. The nozzle includes an interior passage 42 and an air outlet 20 from which the air flow is emitted from the fan. The interior passage extends about an opening or bore 32 through which air from outside the nozzle is drawn by air emitted from the air outlet. The body includes a duct 60 having a first end defining an air inlet 62 of the duct and a second end located opposite to the first end and defining an air outlet 64 of the duct, an impeller 70 is located within the duct for drawing the air flow through the duct, and a motor 94 for driving the impeller. A diffuser section of the duct is annular in shape and converges towards the outlet end of the diffuser. The cross-sectional area of the diffuser varies along the diffuser section by no more than 20% of the cross-sectional area of the air flow path at the inlet of the diffuser.
