Air is accelerated through an annular aperture, creating a high-velocity jet of air. This passes over an airfoil-shaped ramp, channelling its direction and creating areas of low pressure behind and around the fan. The change in pressure forces surrounding air to be drawn into the airflow, resulting in a powerful stream of smooth cooling air.
By reducing turbulence within Dyson Cool™ fans, Dyson engineers were able to make them quieter. To do this, they streamlined the airflow paths within the machines, allowing air to pass through smoothly. They also designed a Helmholtz cavity for each fan, which captures and dissipates sound from the motor.
Reducing turbulence makes the fans quieter, but it also means that less energy is required to move air through them. While the fans still produce powerful airflow, their motors are calibrated to run more slowly, drawing less energy.
Fan can be programmed to turn off after preset intervals ranging from 15 minutes to 9 hours.
With 10 precise airflow settings, sleep timer, on/off and oscillation control. Curved and magnetized to store neatly on the machine.
Airflow can be directed around a room – one touch for smooth oscillation.
No awkward safety grilles or blades.
No fast-spinning blades.
Awarded by the Noise Abatement Society for improved sound quality.
