When working to make the Dyson Airblade dB hand dryer quieter than the original Dyson Airblade™ hand dryer, Dyson engineers focused on reducing sound from two key sources:
Reduced air rush noise
Airblade™ technology results in air travelling at 430mph through apertures measuring just 0.3 mm in width. Some noise is inevitable.
Dyson engineers have reduced the noise produced by the sheets of air by redesigning the shape of the apertures through which air is forced.
Reduced motor noise
Dyson acoustic engineers have made improvements to the level and the quality of the sound generated by the Dyson digital motor V4.
Dyson digital motor V4
The Dyson digital motor V4 was seven years in the making - it's one of the world's smallest fully-integrated 1600W motors. It's the only hand dryer motor powerful enough to draw in up to 35 litres of air a second through a HEPA filter, and then dry hands in 10 seconds.
This long-life energy efficient motor is digitally switched at 6,000 times per second, making the high compression fan spin 90,000 times a minute. There are only three moving parts, so there are no slip rings or carbon brushes to wear down.
Fastest, 10 second dry time
Testing based on the National Sanitation Foundation's Protocol P335 (NSF P335) shows that most other hand dryers are much slower than their manufacturers claim. Many people give up when using a slow hand dryer. But damp hands can spread up to 1,000 times more bacteria than dry hands.
Testing based on NSF P335 proves that the Dyson Airblade dB hand dryer is the fastest. It dries hands hygienically in 10 seconds. Airblade™ technology combined with the Dyson digital motor V4 creates high speed sheets of air that scrape water from both sides of the hands simultaneously. It's the fastest way.
Tough and durable
The Dyson Airblade dB hand dryer is engineered to last. It has been repeatedly tested for durability and resilience to physical and chemical abuse. Dyson Airblade dB hand dryers have also been exposed to real-life environments to ensure that they can withstand the pressures of high usage.
With strong construction and robust materials, the Dyson Airblade dB hand dryer is suitable for high footfall, high usage locations where vandalism can be an issue. And because it uses filtered sheets of 430mph air to dry hands, there is no heating element prone to wear and failure.
The most hygienic hand dryer
Other hand dryers are unhygienic. They don't filter bacteria and viruses from the washroom air. They suck in dirty air then blow it back onto hands. The Dyson Airblade dB hand dryer uses a HEPA filter. 99.9% of bacteria and viruses in the washroom air are captured. So hands are dried using cleaner air, not dirty air.
