Dyson Air Multiplier™

Air Multiplier™ technology

Using an airfoil-shaped ramp (like a cross-section through an airplane wing), airflow is amplified 15 times. 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.

Air Multiplier™ technology amplifies 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 though an annular aperture. It passes over a 16° airfoil-shaped ramp, which channels its direction. 3 Air behind the Dyson Air Multiplier™ fan is drawn into the airflow, through a process known as inducement. 4 Air around the machine is also drawn into the airflow, through a process known as entrainment, amplifying it 15 times.
