Dyson Pure Cool delivering 290 liters of powerful airflow per second

Powerful Air Multiplier™ technology.

Air Multiplier™ technology delivers over 290 litres per second of smooth, yet powerful airflow – circulating purified air throughout the whole room.¹

Dyson Pure Cool two airflow modes

Two airflow modes.

An air valve mechanism is driven by a brushless stepper motor, to allow remote actuation and switching between Backward airflow mode and Fan mode. The stepper motor drives a pinion gear, which turns a rotational baffle driver around the arc of the amplifier. Angled slots in the baffle driver move the baffle forwards and backwards.
