Dyson engineers have re-engineered the apertures of the Dyson Airblade hand dryer to reduce air turbulence. Two sheets of high velocity unheated air travel through the hand dryer's new 0.4mm scallop-shaped apertures, quickly scraping water from hands and leaving them fully dry.
The scallop design increases the distance travelled by the two sheets of air before they collide and an overhanging lip on the front aperture alters the angle of the air exiting the machine, reducing the sound made when the sheets collide.
Helmholtz silencer: a Dyson designed Helmholtz silencer eliminates specific motor tones.
The Dyson digital motor V4: a power dense brushless DC motor, utilising a bonded neodymium magnet encased in a carbon fibre sleeve. It is small, powerful and capable of creating 430mph sheets of air that dry hands quickly and efficiently. It is one of the world’s smallest and fully integrated 1600W motors. Using digital pulse technology, it accelerates from 0-90,000rpm in less than 0.7 seconds.
Materials: made from PC ABS (Polycarbonate Acrylonitrile Butadiene Styrene). The Dyson Airblade dB hand dryer is a specific mixture of both these materials – 70% PC and 30% ABS. It has been repeatedly tested for durability and resilience to physical and chemical abuse.
Colour finishes: grey or white.
Hygiene: passes washroom air through a HEPA filter to remove 99.9% of bacteria before it is blown onto hands.
Environmental impact: uses 62% less CO2 than paper towels and at least 67% less C02 than some other warm-air hand dryers.
Guarantee: 5 year parts, 1 year labour.
Running cost: dries 18 pairs of hands for the price of a single paper towel and costs $40 a year to run.
