Abstract: A fan for generating an air current includes a body having an air inlet, and a nozzle connected to the body. The nozzle includes an interior passage for receiving an air flow from the body and an air outlet from which the air flow is emitted from the fan. The interior passage extends about an opening or bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The body includes a duct having an air inlet and an air outlet, an impeller located within the duct for drawing the air flow through the duct, and a motor for driving the impeller. A noise suppression cavity is located beneath the air inlet of the duct. The cavity has an inlet which is located beneath, and is preferably concentric with, the air inlet of the duct.

Abstract: Described is a fan assembly comprising a body comprising an inlet, an outlet, and means for generating an air flow. 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 and a nozzle retaining means for releasably retaining the nozzle on the body. The nozzle retaining means has a first configuration in which the nozzle is retained on the body and a second configuration in which the nozzle is released for removal from the body. The fan assembly also comprises a manually actuable member located on the nozzle for effecting movement of the nozzle retaining means from the first configuration to the second configuration.

Abstract: A fan for generating an air current includes a body having an air inlet, and a nozzle connected to the body. The nozzle includes an interior passage for receiving an air flow from the body and an air outlet from which the air flow is emitted from the fan. The interior passage extends about an opening or bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The body includes a duct having an air inlet and an air outlet, an impeller located within the duct for drawing the air flow through the duct, and a motor for driving the impeller. An annular guide member extends about the duct for guiding air from the air inlet of the body to the air inlet of the duct. The guide member defines with the duct an annular noise suppression cavity.

Abstract: A fan assembly includes a body and a nozzle connected to the body. The body includes an impeller, a motor housing, and a motor located within the motor housing for driving the impeller. The impeller has a substantially conical hub connected to the motor, a plurality of curved vanes connected to the outer surface of the hub, and an annular vane connected to the base of the hub. The motor housing has an annular groove for receiving at least the tip of the annular vane, and an annular lip forming a drip edge extending about the motor housing, the annular lip defining an outer peripheral wall of the groove.
