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 partially permeable and in fluid contact with air in the air flow duct and gas in the cavity and is configured to attenuate noise transmitted between the duct and the cavity. The resistive screen and the cavity together define a noise-damping resonator.

Noise reduction for air flow devices

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.

A nozzle for a fan assembly includes an air inlet, a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve includes one or more valve members that are moveable to simultaneously adjust the size of the first air outlet and inversely adjust the size of the second air outlet. The nozzle further includes a third air outlet and a fourth air outlet, the third air outlet being opposite the fourth air outlet, the third and fourth air outlets being oriented in convergent directions.

Nozzle for a fan assembly

There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve comprises one or more valve members that are moveable to simultaneously adjust the size of the first air outlet and inversely adjust the size of the second air outlet. The nozzle further comprises a third air outlet and a fourth air outlet, the third air outlet being opposite the fourth air outlet, the third and fourth air outlets being oriented in convergent directions, and the third air outlet and the fourth air outlet each being substantially perpendicular to each of the first and second air outlets.
