Dyson Air Multiplier, fan without blades
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 Air Multiplier™ technology to
amplify air 15 times, expelling 405 litres of cool, smooth and uninterrupted
air every second.
Air is accelerated
through an annular aperture set within the loop amplifier. This creates
a jet of air which passes over an airfoil-shaped ramp that channels its
direction. Surrounding air is drawn into the airflow (this is called inducement
and entrainment).
Dyson’s
fluid dynamics engineers ran hundreds of simulations to measure and map
airflow – allowing them to precisely optimise how the Dyson Air
Multiplier™ fan works.
The Dyson Air
Multiplier™ fan is powered by an efficient brushless motor and air
speed can be precisely adjusted with dimmer-switch control. Fans with
blades are only wired to run at just two or three settings.
No blades means
no need for a grille; so it’s simple to and safe 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.
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.
So we’ve developed a new type of fan that doesn’t use blades.”
With its simple loop the Dyson Air Multiplier™ fan is quickly wiped
clean with a cloth. Fans with blades 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.
Unlike top-heavy conventional fans, the Dyson Air Multiplier™ fan
has an energy-efficient motor is at its base, meaning it has a low centre
of gravity and doesn’t topple over.
You have to use two hands to position a fan with blades. The Dyson Air
Multiplier™ fan adjusts easily with a touch of the hand. It pivots
on its low centre of gravity and stays put.
Fans with blades have limited settings. The Dyson Air Multiplier™
fan uses an energy-efficient brushless motor, which means air speed can
be precisely adjusted up or down. The airflow control switch control allows
people to pick their perfect airflow.
The Dyson Air
Multiplier™ fan is constructed from tough Acrylontride butadiene
styrene – ABS (C8H8 C4H6 C3H3N)n). 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 Dyson Airblade™
hand dryers too.
The Dyson Air Multiplier™ fan costs from £199
