Air Multiplier™ technology

Air is drawn in

Up to 33 litres 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.

Air is accelerated

Airflow is accelerated though an annular aperture. It passes over an airfoil-shaped ramp, which channels its direction.

Air is induced

Air behind the machine is drawn into the airflow, through a process known as inducement.

Air is entrained

Air around the machine is also drawn into the airflow, through a process known as entrainment, amplifying it up to 18 times.

Other technologies in Dyson fans and heaters

Mixed flow impeller

To draw in the air required to generate a powerful enough jet, Dyson engineers developed a mixed flow impeller. It combines the technologies used in turbochargers and jet engines. It has nine asymmetrically aligned fins with rows of tiny holes that reduce the friction caused by colliding high and low air pressure.

Brushless motor

Dyson fans and fan heaters use energy-efficient, brushless DC motors, so you can precisely control airflow.
