Abstract: A fan assembly, including a fan body including an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly is arranged to removably engage with the fan body and to cover at least a portion of the inlet surface when engaged with the fan body. The filter assembly includes a filter and a housing for the filter, the housing being provided with a filter retention assembly for releasably retaining the filter in the housing, and a user interface for actuating the filter retention assembly to release the filter from the housing. Upon actuation of the filter retention assembly via the user interface, the filter is free to slide relative to the housing. Preferably, the user interface is positioned on the housing.

Abstract: A fan assembly comprising an airflow generator and a nozzle. The nozzle comprising a body defining an air inlet to receive generated airflow, an air outlet section, and a switching member. The switching member switches between a first position, delivering only a first airflow to the outlet, and a second position, delivering both first and second airflows. The air outlet section comprises a first inlet for the first airflow, a second inlet for the second airflow, an air outlet for emitting airflow from the fan assembly, and pathways between the first inlet and the air outlet. In the first position, the first airflow travels along the first pathway and is emitted in a first outlet direction. In the second position, the second airflow interacts with the first, redirecting it along the second pathway, and emitting it in a second, different outlet direction.

Abstract: An air amplifier for directing airflow from a fan assembly, and a fan assembly including an air amplifier. The air amplifier includes an inlet for receiving airflow from a fan assembly, and an airflow cavity. The airflow cavity includes a first wall and a second wall that define an airflow passageway extending towards an exhaust outlet for emitting air. A lip is provided at or towards a front edge of the first wall. The lip extends towards the second wall, thereby partially inhibiting airflow from the exhaust outlet.

Abstract: A nozzle for a fan assembly is described. The nozzle includes a first duct through which a first airflow moves, the first duct having a first outlet for emitting the first airflow. The nozzle further includes a second duct through which a second airflow moves, the second duct having a second outlet for emitting the second airflow. The first and second outlets are arranged such that the first and second airflows collide to generate a combined airflow having a direction defined by the relative flow rates of the first and second airflows. The first duct then includes a portion moveable to vary the flow rate of the first airflow.

Abstract: There is provided an air-treatment device including an airflow generator for generating an airflow, an adsorbent material for adsorbing one or more airborne contaminants, the adsorbent material being arranged such that at least a portion of the airflow passes through the adsorbent material, a heater arranged to heat a portion of the adsorbent material to desorb adsorbed contaminants, and a photocatalytic reactor arranged to receive air containing the contaminants desorbed from the heated portion of adsorbent material. The photocatalytic reactor includes a photo-catalyst for photocatalytic degradation of one or more of the contaminants, and one or more light sources for illuminating the photo-catalyst to facilitate photocatalytic degradation. The air-treatment device is arranged such that at least a portion of the airflow that has not passed through the heated portion of the adsorbent material contacts the one or more light sources.

Abstract: A fan assembly, including a fan body including first and second retention assemblies and an inlet surface defining an air inlet. A motor-driven impeller contained within the fan body generates an airflow. A filter assembly attached to the fan body includes one or more flexible filter media, a first engagement element positioned at first edge of the filter media, and a second engagement element positioned at a second, opposite edge of the filter media. The filter assembly is furlable, and the first and second engagement elements releasably engage with the respective first and second retention assemblies of the fan body to retain the filter assembly tautly over the inlet surface in an at least partially unfurled state, such that, in use, airflow drawn through the air inlet by the motor-driven impeller is drawn through the filter media. The fan body is cylindrical in shape and the filter assembly wraps around substantially all the fan body.

Abstract: There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet for receiving an air flow, a first air outlet for emitting an air flow and a second air outlet for emitting an air flow. The first and second air outlets comprise a pair of curved slots that are provided on a face of the nozzle, and the first and second air outlets are oriented towards a convergent point. The first air outlet and the second air outlet may be oriented towards a convergent point that is located on a central axis of the face of the nozzle.

Abstract: A device configured to generate an air flow, the device including: a compressor; an air flow duct arranged to convey a flow of air generated by the compressor; a gas-filled cavity disposed beside the air flow duct; a wall separating the air flow duct and the cavity, the wall including at least one aperture; and an acoustic resistive screen covering and held in tension over the aperture of the wall. The screen is in fluid contact with air in the air flow duct and gas in the cavity and is configured to resist air flow between the duct and the cavity. The resistive screen and the cavity together define a noise-damping resonator.
