In October 2009, the internet was blasted with news of Dyson Appliances ’ latest innovation with the world’s first blade-less fan, the new Dyson Air Multiplier. Excitingly, Australia played host to the global retail launch of this blade-less fan.
Six months down the track at DesignEX 2010, Dyson now launches its breakthrough cooling technology for commercial buyers, architects and the design industry.
“We’re very excited to introduce the Air Multiplier fan to the architecture and design industry where smart technology and cutting edge design is paramount. Air Multiplier technology strips away the traditional workings of these cooling appliances to deliver an efficient product that will significantly enhance any modern fit-out, be it residential or commercial.” says Ross Cameron, managing director of Dyson SEA.
The Dyson Air Multiplier blade-less fan uses patented technology to multiply air 15 times, expelling 450 litres of cool, smooth and uninterrupted air every second.
Air is accelerated through an annular aperture. This blade-less fan creates a jet of air which passes over an airfoil ramp that channels its direction. Surrounding air is drawn into the airflow amplifying it 16 times (this is called inducement and entrainment).
Dyson’s fluid dynamic engineers ran hundreds of simulations to measure and map airflow – allowing them to precisely optimise how the Dyson Air Multiplier blade-less fan works.
The Dyson Air Multiplier blade-less fan is powered by an energy efficient brushless motor, so air speed can be precisely adjusted with a dimmer switch. Conventional fans are only wired to run at just two or three settings.
No blades means no need for a grille, so it’s simple to clean and straying fingers are safe too.
And because its motor is at its base, the Dyson Air Multiplier blade-less 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.
