Powered by the Dyson digital motor V9

The Dyson Airwrap™ styler is powered by the Dyson digital motor V9. Spinning at up to 110,000rpm, generating 3.2kPa, it’s powerful enough to produce the air pressure needed to create the Coanda effect.

What is the Coanda effect?

The Coanda effect is an aerodynamic phenomenon. Air, when propelled at the right speed and pressure, naturally follows an adjacent surface, entraining surrounding air. The Dyson Airwrap™ styler creates a spinning vortex of air around the barrel that gently attracts, wraps and curls hair.
“Our digital motor technology gives us the high-pressure, high-velocity airflow needed to create the Coanda effect.” Graham Donald Senior Motor Drives Engineer

The science of styling with no extreme heat

To style hair you can reposition and reform the hydrogen bonds that hold its shape. Discover how the Dyson Airwrap™ styler does it with no extreme heat.

Intelligent heat control

Temperatures above 150° can cause extreme heat damage. Above 230°, hair melts. The Dyson Airwrap™ styler’s thermistor measures airflow temperature over 40 times every second. It transmits data to the machine’s microprocessor which intelligently controls the heating element, keeping the temperature under 150°C. To prevent extreme heat damage.
