Dyson has rethought the hair dryer, making it supersonic and quiet

Dyson’s fanless fan engineering has allowed the company to produce some desirable new gadgets that carry hefty price premiums. They’ve also been blamed for helping to spread viruses much more effectively in the right environments. Now the engineers at Dyson have applied their Air Multiplier technology to another device: the hair dryer.

Just like with fans and hand dryers, the design of the hair dryer hasn’t really changed much since its inception. They are noisy handheld devices that create a lot of heat and airflow to get hair dry or styled. However, Dyson has rethought how they work, used Air Multiplier, and created a supersonic, quiet alternative.

The open nature of this new dryer is typical of the fanless design Dyson has made its own. The low noise is achieved by using a rubber isolation mount, which stops the electric motor from vibrating against the casing. At the same time, the 13 impeller blades inside spin up to 110,000rpm, giving ample air movement combined with an intelligent heat monitor.

A glass bead thermistor and microprocessor work together to check the heat of the air 20 times a second and adjusts accordingly to maintain the desired temperature. The end result being this dryer won’t damage hair while allowing heat settings including 28, 60, 80, or 100 degrees Celsius.

Dyson is officially calling it the Dyson Supersonic hair dryer. It has apparently taken 4 years to develop, involved the creation of over 600 prototypes, and cost $71 million. They’ve also tested it on over 1,000 miles of hair. With that in mind, nobody should be surprised to see the price set at $435.
