Air Multiplier™ technology
Dyson fans use Air Multiplier™ technology to create a powerful stream of uninterrupted airflow.
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.
