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. A support assembly supports the nozzle on a ceiling. The support assembly includes a ceiling mount for mounting the ceiling fan on a ceiling, an arm having a first end connected to the ceiling mount, and a body connected to a second end of the arm and the annular nozzle. The body is pivotable relative to the arm about a pivot axis to move the annular nozzle between a raised position and a lowered position.
