Coanda styling pioneered by Dyson: The Dyson Airwrap multi-styler harnesses an aerodynamic phenomenon called the Coanda effect. It uses air to attract and wrap hair to the barrel or surface of the brush. Powered by the Dyson digital motor V9: The 13-blade impeller spins at up to 110,000rpm, generating 3.2kPa. Powerful enough to produce the air pressure that creates the Coanda effect. Intelligent heat control: Measures airflow temperature over 40 times a second, intelligently controlling the heating element to prevent heat damage. Negative ions: Charged particles in the airflow help reduce static in the hair. Airflow speed - Three precise airflow speeds to suit your styling preference. Temperature control - Three precise heat settings.
