The Dyson Air Multiplier™ fan has no blades. Instead it uses protected technology to multiply air 15 times, expelling 450 l of cool, smooth and uninterrupted air every second. The Dyson Air Multiplier™ fan is powered by an energy efficient brushless motor and air speed can be precisely adjusted with a dimmer switch. No blades means no need for a grille; so it’s safe and simple to clean. And because its motor is at its base, the Dyson Air Multiplier™ fan can be tilted with a touch.
