Welcome to the Dyson Press Centre

Say goodbye to the blade. No blades. No buffeting.

Chop, chop. The blades on conventional electric fans literally chop the air, which means the airflow is uneven, causing unpleasant buffeting.

The Dyson Air Multiplier™ fan has no blades. Instead it 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 creates a jet of air which passes over an airfoil ramp that channels its direction. Surrounding air is drawn into the airflow amplifying it 15 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™ works.

The Dyson Air Multiplier™ 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™ can be tilted with a touch, unlike a conventional top-heavy fan, which needs to be positioned with two hands and can topple easily.

James Dyson says:

I’ve always been disappointed by fans. Their spinning blades chop up the airflow, causing annoying buffeting. They’re hard to clean. And children always want to poke their fingers through the grille. More chopping. So we’ve developed a new type of fan that doesn’t use blades.

Dyson Air Multiplier™: the facts

No buffeting

The blades on conventional fans cause unpleasant buffeting because they chop the air. Dyson Air Multiplier™ technology gives an uninterrupted stream of air that doesn’t distract or buffet you.

Hygienic

With its simple loop the Dyson Air Multiplier™ is quickly wiped clean with a cloth. Conventional bladed fans are nigh on impossible to clean, with dust and dirt building up inside the cage. The same dust and dirt is then billowed into your face when the fan is switched on.

Stable

Unlike top-heavy conventional fans, the Dyson Air Multiplier™ has an energy-efficient motor is at its base, meaning it has a low centre of gravity and doesn’t topple over.

Touch-tilt

You have to use two hands to position a conventional fan. The Dyson Air Multiplier™ adjusts easily with a touch of the hand. It pivots on its low centre of gravity and stays put.

Variable airflow

Conventional fans have limited settings. The Dyson Air Multiplier™ uses an energy-efficient brushless motor, which means air speed can be precisely adjusted up or down. The dimmer-switch control allows people to pick their perfect airflow.

One-touch oscillation

To oscillate a conventional fan you have to hold it steady, pull the toggle and watch it judder. Oscillating the Dyson Air Multiplier™ through 90º is simple. Press the button.

Strong

The Dyson Air Multiplier™ is constructed from tough Acrylontride butadiene styrene – ABS (C8H8 C4H6 C3H3N). ABS is a tough thermoplastic used to make light, rigid and moulded products. It has shock absorbing properties and is used to make car bumpers, crash helmets and modern golf club heads. It’s used in Dyson vacuum cleaners and Airblade™ hand dryers too.

The Dyson Air Multiplier will be available in stores from 21st October 2009 for $379RRP (25cm) and $399RRP (30cm).
