The Air Multiplier promises to be 15 times more efficient than a standard fan, despite its lack of blades.The Air Multiplier marks a departure for Sir James, being the first new product category his company has moved into since the creation of the Airblade, a hand dryer that hit the market three years ago.
Dyson is confident that the design – a large ring of plastic on top of a pedestal – and technology is radical enough to persuade people to spend extra on the product.
As well as being more efficient, it “is dead easy to clean,” said Sir James.
“I am very proud. We’ve been working on this for four years,” he said.
The Air Multiplier works by sucking in one unit of air at the base, and pushing it out at speed through a thin gap in the fan’s ring. The expelled air is pushed out over an airfoil-shaped ramp (similar in shape the wing of an aeroplane). In doing so, surrounding air is drawn into the air flow, so by the time the cool air hits an office worker’s face, it is the equivalent of 15 units of air.
In all, 405 litres of air are expelled every second.
However, Sir James insists it is not just more efficient than a standard fan – which expels one unit of air for every one taken in – it also creates a far smoother airflow.
“Normal fans chop up the air with the blade, which is very uncomfortable when you are sitting in front of a fan. It buffets you. This is far smoother.”
James Dyson explains the working of his latest invention
Dyson hopes that while the market for fans in Britain is relatively small, America, Australia and Japan will snap up the device.
The fans will be made in Malaysia, as all of Dyson’s products now are. “But, crucially, they will be exported from Britain,” said Sir James. “We do all our research and development in Wiltshire, and we pay taxes here.”
