Abstract: There is provided a photocatalytic reactor arranged to receive one or more airborne contaminants. The photocatalytic reactor includes a photo-catalyst for photocatalytic degradation of one or more of the contaminants disposed on a substrate, and a light-emitting diode circuit board comprising a circuit board with one or more first light-emitting diodes mounted to a first side of the circuit board and one or more second light-emitting diodes mounted to a second side of the circuit board. The substrate is arranged to be illuminated by both the one or more first light-emitting diodes and the one or more second light-emitting diodes in order to facilitate photocatalytic degradation.

Abstract: A nozzle for a fan assembly is described. The nozzle includes a first duct through which a first airflow moves, and a second duct through which a second airflow moves. The first duct has a first outlet for emitting the first airflow, and the second duct has a second outlet for emitting the second airflow. The first and the 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 second duct has a constant restriction, and the first duct has a variable restriction to vary the flow rate of the first airflow.

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 divider body is provided within the passageway. The divider body divides the airflow passageway into a first exhaust passageway and a second exhaust passageway. The divider body tapers towards the exhaust outlet.

Abstract: There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, 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 together defining an aggregate air outlet of the nozzle, a single internal air passageway extending between the air inlet and the first and second air outlets, and a valve for controlling an air flow from the air inlet to the first and second air outlets. The valve comprises one or more valve members that are moveable to adjust the size of the first air outlet relative to the size of the second air outlet while keeping the size of the aggregate air outlet of the nozzle constant, and wherein the air outlets are oriented towards a convergent point

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.
