Abstract

A ceiling fan includes an annular nozzle having an inner wall, an outer wall extending about the inner wall, an air inlet for receiving an air flow, an air outlet for emitting the air flow, and an interior passage located between the inner wall and the outer wall for conveying the air flow to the air outlet. The inner wall defines a bore through which air from outside the nozzle is drawn by the air flow emitted from the air outlet. The fan includes a support assembly for supporting the nozzle on a ceiling. The nozzle is rotatable relative to the support assembly about a rotational axis and between a first orientation in which the air flow is directed away from the ceiling and a second orientation in which the air flow is directed towards the ceiling.
