Air Multiplier™ technology

A Dyson fan uses an airfoil-shaped ramp (like a cross-section through an airplane wing) to amplify airflow from 15 to 18 times depending on the model. This creates a smooth, powerful airflow, with no need for fast-spinning blades.

Blades cause buffeting

The blades on conventional fans cause unpleasant buffeting because they chop the air before it hits you.

No blades. No buffeting.

A Dyson fan uses Air Multiplier™ technology to amplify surrounding air, giving an uninterrupted stream of smooth air.

How Air Multiplier™ technology amplifies surrounding air

1 Up to 5.28 gallons of air per second is drawn in by an energy-efficient, brushless motor. A combination of the technologies used in turbochargers and jet engines generates powerful airflow. 2 Airflow is accelerated through an annular aperture. It passes over a 16° airfoil-shaped ramp, which channels its direction. 3 Air behind the Dyson fan is drawn into the airflow, through a process known as inducement. 4 Air around the Dyson fan is also drawn into the airflow, through a process known as entrainment, amplifying it 15 times.
