To make fans work quietly, manufacturers use slow-running motors to spin the blades. This reduces noise but also reduces power, producing weak airflow. To make powerful fans, they use fast motors to spin the blades.
But fast motors create more noise. Powerful and quiet is very difficult to achieve in a conventional fan. The new Dyson Cool™ AM07 tower fans have been engineered to be quieter, consume less energy and have streamlined air channels for reduced airflow turbulence to be 60% quieter than AM02 – yet generate powerful airflow.
Air Multiplier™ technology
Air is accelerated through an annular aperture, drawing in surrounding air to project smooth, powerful, high-velocity airflow. No blades. No choppy air
Streamlined air channels for reduced airflow turbulence make AM07 60% quieter than AM02. A Helmholtz cavity captures and dissipates audible motor noise.
