Dyson Air Multiplier(TM) fan features loop amplifier, 1.3 mm annular aperture, and airfoil-shaped ramp that amplify air motion by 15x. It also includes energy-efficient brushless motor at machine base. Available in two 10 in. models and 12 in. model, device allows air speed to be adjusted with dimmer switch.
James Dyson introduces the bladeless fan. No blades. No buffeting.
CHICAGO, Oct. 12 / / - James Dyson, who for the past 30 years has continuously revolutionized the vacuum cleaner industry, has turned his attention to addressing the everyday fan. As a result, he has designed the Dyson Air Multiplier(TM) fan, which has no blades. Instead, it uses a unique technology to multiply air 15 times, and through unprecedented advancements in airflow engineering, expels 119 gallons of smooth and uninterrupted air every second.
Until today, conventional electric fans have gone largely unchanged. The fundamental problem has remained the same for more than 125 years; the blades chop the air creating an uneven airflow and unpleasant buffeting.
Dyson's fluid dynamics engineers spent four years running hundreds of simulations to precisely measure and optimize the machine's aperture and airfoil-shaped ramp before perfecting Dyson's Air Multiplier technology. Air fluctuations were mapped with Laser Doppler Anemometry, helping measure control the machine's airflow.
"We realised that this inducement, or amplification, effect could be further enhanced by passing airflow over a ramp," says Dyson. "And of course this was the point where the idea of a bladeless fan became a real possibility. Here was a way to create turbulent-free air and finally do away with blades."
How it works: inducement and entrainment
Air is drawn into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil-shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15 times. The result is a constant uninterrupted flow of cooling air.
The Dyson Air Multiplier fan is powered by an energy efficient brushless motor and air speed can be precisely adjusted with a dimmer switch. Conventional fans are wired to run at just two or three settings.
No blades mean no need for a grille and 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, unlike a conventional top-heavy fan, which needs to be positioned with two hands and can topple easily.
The Dyson Air Multiplier fan is available in two 10-inch models: blue & iron and silver & white with an MSRP of $299.99. A 12-inch model is available in silver & iron with an MSRP of $329.99. All three machines are available at The Conran Shop (NY), Luminaire (Chicago/Miami) and Twentieth (LA). To learn more about the Dyson Air Multiplier fan visit www.dyson.com.
