Reducing the turbulence of high velocity air whilst retaining high performance is a challenge. Dyson Cool™ fans (AM06, AM07, AM08) powered by Air Multiplier™ technology, have been developed over three years following an investment of £40m. Reengineered airflow paths, an aerodynamic diffuser and a Helmholtz cavity mean that our machines are now up to 75% quieter.
