New V4 Dyson Airblade Motor
The Dyson Airblade new models (AB14, AB12, AB09, AB10, AB11) now use the new V4 motor. The Dyson digital motor V4 spins at 92,000 a minute - generating enough power to draw in 28 liters of air per second. The Dyson digital motor V4 was seven years in the making - it's one of the world's smallest fully-integrated 1400W motors. It's the only hand dryer motor powerful enough to draw in 28 liters of air a second through a HEPA filter, and then dry hands in 12 seconds. This long-life, energy-efficient motor is digitally switched at 6,100 times per second, making the high compression fan spin 92,000 times a minute. There are only three moving parts, so there are no slip rings or carbon brushes to wear down.
Original Dyson Airblade Digital Motor
The Dyson digital motor is smaller, lighter and more powerful than a conventional motor. It spins at up to 81,000rpm – five times faster than the engine of a racing car. At that speed, it can suck in 68 cubic feet of washroom air every minute.

How the Dyson Airblade Works:
- Dirty washroom air is sucked in by the Dyson digital motor.
- It passes through a HEPA filter, removing over 99.9% of the bacteria from the air used to dry your hands.
- The clean air passes over the electronics, cooling them.
- The air then reaches the motor, which channels it up and through the machine.
- Air passes into the air ducts, which are insulated to reduce noise.
- It’s then forced through two apertures – creating sheets of air traveling at 400mph, which literally scrape water from hands.
*For the cost of just one paper towel, the Dyson Airblade™ hand dryer can dry up to 22 pairs of hands.
