Unbelievable – a hand-drier that actually works

They were properly dry: not half-damp as they would be after a protracted session with a conventional dryer. It was soon apparent that, if this science was properly applied hand drying could be revolutionised.
Thousands of design hours were spent finding the most aerodynamic and efficient way of driving pressurised air through a finely-engineered aperture of less than 0.3 millimetres. Ergonomically curved to ensure that the whole hand is coated with air (including the fine crevasses between the fingers and backs of hands), this gap - the machine's 'blade' -delivers a curtain of air at a constant, uniform pressure.
Simply put, it's the first hand dryer that actually works properly. It’s tough and has been put through its paces to make sure it withstands the toughest washroom environment.
The Dyson Digital Motor: The Dyson Digital Motor (DDM) is at the Dyson Airblade's core. A small, long-life, low-energy and brushless motor spinning at 1,666 revolutions per second, DDM produces enough air pressure for the Dyson Airblade to dry hands without the need for heat.
Buying Dyson Airblade: Dyson Airblade will be sold in the UK for UKP549 (excluding VAT). Machines can be leased directly from Dyson too.
Clive Beggs, Professor of Medical Technology, University of Bradford, said: "The Dyson Airblade hand dryer is hygienically superior to conventional warm air driers and it has the potential to greatly improve hand drying compliance and reduce the spread of infections.
"We all know that washing your hands helps to prevent the spread of infection. However, what many of us don’t realise is that the hand drying process can be as important as hand washing itself.
