Dyson Quietly Clears Out the Supersonic, Salon-Grade Hair Dryer Now Going for Peanuts - Kotaku
"The Supersonic Origin places the motor at the handle instead of the head and entirely alters the balance and handling. Classic hair dryers place a cumbersome motor at the top and cause your arm to tire within minutes and producing that unpleasant weight distribution. Dyson's V9 digital motor rotates at 110,000 rpm which is ridiculously quick next to standard dryers that top at 20,000 rpm."
"Its smart heat control system takes air temperature readings 40 times per second and transmits the readings to a microprocessor that controls the heating element. The result is that the air temperature never goes above 302°F and that's important because hair damage takes off at a very rapid rate above that temperature. Drugstore dryers are not very temperature-controlled at all and can easily reach 350-400°F and they fry the protective cuticle layer on your hair."
Dyson applies vacuum airflow engineering to the Supersonic Origin to dry hair faster and reduce heat damage. The motor sits in the handle to improve balance and reduce arm fatigue. A V9 digital motor spins at 110,000 rpm, driving 13 liters per second to create a concentrated, high-velocity airbeam that dries hair internally rather than overheating the surface. A smart heat control system measures air temperature 40 times per second and prevents air from exceeding 302°F, protecting the hair cuticle while drugstore dryers can reach 350–400°F. The device is currently discounted to $299 from $419.
