The Dyson AM07 Cooling Tower Fanfeatures one-touch oscillation and Air Multiplier technology to direct even airflow around the room. Air Multiplier technology gives an uninterrupted stream of smooth airflow Smooth oscillation – directs airflow around the room 15 minutes to 9 hours sleep timer Powerful yet quiet airflow Safe – no fast-spinning blades Easy to clean – no awkward safety grille or blades Comes with remote control Curved and magnetised remote – for neat storage Air Multiplier technology No blades, no choppy air! 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. Improved energy efficiency Reducing turbulence makes the fan quiet, but it also means that less energy is required to move air through it. While the fan produces powerful airflow, its motor is calibrated to run more slowly, drawing less energy.
