Dyson Fans with Air Multiplier Technology

Dyson fans and fan heaters work very differently to conventional fans and electric heaters. They don’t have fast-spinning blades that chop the air and cause uncomfortable buffeting. Instead, they use Air Multiplier™ technology to draw in air and amplify it up to 18 times, producing an uninterrupted stream of smooth air. 

Air is drawn out:
Up to 27 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 called entrainment, amplifying it up to 18 times.
