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.
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.
Airflow is accelerated though an annular aperture. It passes over an airfoil-shaped ramp, which channels its direction.
Air behind the machine is drawn into the airflow, through a process known as inducement.
Air around the machine is also drawn into the airflow, through a process known as entrainment, amplifying it up to 18 times.
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.
Mixed flow impeller
Dyson fans and fan heaters use energy-efficient, brushless DC motors, so you can precisely control airflow.
