Abstract: Described is a fan assembly comprising a body comprising an air inlet, an air outlet, and means for generating an air flow through the body. The body has a lower body section and an upper body section capable of rotation relative to the lower body section. The fan assembly also comprises a nozzle for emitting the air flow, and a filter upstream from the air inlet, wherein the upper body section has a seat for supporting the filter such that the filter rotates relative to the lower body section when the upper body section is caused to rotate.

Abstract: Described is a fan assembly comprising a body comprising an inlet, an outlet, and a means for generating an air flow through the body. The fan assembly also comprises a nozzle mountable on the body for receiving the air flow from the body and for emitting the air flow, wherein the body and the nozzle have cooperative inclined surfaces configured to assist alignment of the nozzle on the body.

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 and 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 and 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 and lowered position.

Abstract: A fan assembly for generating an air flow within a room includes an annular casing which defines an interior passage. The interior passage includes an air inlet, and houses, downstream from the air inlet, an impeller and a motor for driving the impeller to draw an air flow through the air inlet and into the fan assembly. The interior passage also has an air outlet from which at least a portion of the air flow is emitted from the fan assembly. The annular casing defines a bore about which the interior passage extends and through which a secondary air flow from outside the fan assembly is drawn by the air emitted from the air outlet.

Abstract: A fan assembly for generating an air flow within a room includes an impeller and a motor for driving the impeller to draw an air flow into the fan assembly, and a casing having an interior passage with a scroll section having a cross-sectional area that decreases from a scroll inlet section to a scroll outlet section. The scroll inlet section has an inlet port for receiving the air flow and the scroll outlet section has an outlet port for returning a first portion of the air flow to the scroll inlet section. The scroll section includes an air outlet for emitting a second portion of the air flow from the casing. The casing defines a bore through which air from outside the fan assembly is drawn by the air emitted from the air outlet.
