Abstract
An annular nozzle for a ceiling fan includes an inner wall defining a bore having a bore axis, an outer wall extending about the inner wall, an air inlet for receiving an air flow, and an air outlet section extending between the inner wall and the outer wall. The air outlet section defines an air outlet for emitting the air flow. An interior passage extends about the bore axis for conveying the air flow to the air outlet. The air outlet section is configured to emit the air flow away from the bore axis.
