The new Dyson Cool™ fan

Same powerful airflow, now 75% quieter
 
Five years ago, Dyson bid farewell to the blade by inventing the world's first bladeless fan, the Dyson Air Multiplier™. Never satisfied, Dyson engineers have spent the past three years improving their original design. They went to painstaking lengths to acoustically engineer a fan that is 75% quieter than its predecessor, while maintaining the same powerful airflow.

James Dyson: “Getting rid of blades solved the frustration of unsafe grilles and choppy air. But high speed air creates noise, which can be difficult to disguise. Dyson Cool is engineered to deliver powerful, smooth air, without the nuisance of noise.”

Acoustic engineering
High speed air creates noise. But tuning out unwanted noise poses a significant engineering challenge.  A specialist team of Dyson acoustic engineers designed a Helmholtz cavity to capture sound waves travelling through the fan. The cavity alone eliminates tones of up to 1,000Hz; similar to the tone produced by a mosquito's beating wing. Watch the engineers explain the challenge here.

How does Air Multiplier™ technology work?
Air is drawn in by an energy-efficient, brushless motor. Airflow is then accelerated through an annular aperture, passing over an air foil-shaped ramp, which draws in and channels its direction. This creates and projects powerful, smooth, high velocity airflow.

The new Dyson Cool™ fan is the result of a £40 million pound investment in research and development. Equipped with a remote control, a sleep timer and ten precise airflow settings, the Dyson Cool™ fan allows you set the time (up to nine hours), and go to sleep as it projects air to cool you. As with all Dyson fans, the Dyson Cool™ fan is safe and easy to clean.
