With Britain set to sweat through a week of soaring temperatures, designer Sir James Dyson has declared war on ‘inefficient’ air-conditioning with the launch of a new range of fans today.
The British inventor of the cyclone vacuum cleaner reckons his latest invention – jet-engine technology fans – are both cheaper and better than air-conditioning units.
He said: ‘Air conditioning is inefficient and gives little or no ventilation. We want to take on air conditioning.’
With over 100 patents pending, the technology inside Dyson’s bladeless fans works by sucking up to 33 litres of air into the cyclone accelerator, in a similar way to a jet-engine or a turbo-charger in a car.
The new top-of-the-range Dyson Pedestal fan multiplies the trapped air by 18 times, before blasting out a cooling breeze over an airfoil ramp without the need for conventional fan blades.
‘Air conditioning is one of the biggest drains on electricity in homes and offices,’ he added. ‘It’s also expensive and often impractical to install.
‘Our new fans offer a better alternative; they move a large volume of smooth, non-buffeted air by amplifying it.’
Air is sucked in through the base by a 40 watt electric motor, and then pushed out at high speed through a lip which runs around the inside of its circular head.
As this is forced out, other air is drawn into the airflow, resulting in the expulsion of 405 litres every second.
The fan also has a dimmer-type switch, which means the powerful current can be easily controlled.
Without blades, curious children will not catch their hands in it, and the simple design makes it easy to clean.
At 1 metre high and only 19 centimetres wide, the AM02 Tower is slender and running track shaped to take up limited floor space.
Around 33 litres of air are drawn in each second and amplified 16 times using Air Multiplier technology.
The AM03 Pedestal draws in 33 litres of air per second and amplifies the air 18 times.
The machine extends from a height of 1.2 metres to 1.4 metres for use in larger areas including living rooms and offices.
Dyson, 62, is estimated to be worth around £500million, and became one of Britain’s best-known inventors after the success of his bagless vacuum cleaner.
Dyson employs 2,500 people worldwide and is increasing its UK workforce to 1,600, with laboratories in Wiltshire specialising in microbiology, as well as fluid, electrical, thermal, acoustic and software engineering.
The Dyson Pedestal and Tower fans are available online from today priced at £299.99
