Dyson Airblade dB hand dryer - Features

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 690 km/h 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.

The latest 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.

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 latest Dyson digital motor V4 creates high speed blades of air that scrape water from both sides of the hands simultaneously. It's the fastest way.

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 690 km/h air to dry hands, there is no heating element prone to wear and failure.

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.

Other hand drying methods are expensive to run. Paper towels need constant
re-stocking and disposal.

Dyson Airblade™ hand dryers produce up to 72% less CO2 than some other hand dryers and up to 68% less than paper towels.¹

No other hand dryers meet every part of NSF Protocol 335.

The Dyson Airblade dB hand dryer has been approved by HACCP as being hygienically safe for use in the food and beverage industry.

"The technology addresses a number of unacceptable risks posed by hand dryers in the past. It's easy to clean and is a touch-free system. It also has a fast dry cycle. With the inclusion of a HEPA filter, these features combine to considerably reduce the risk of microbiological contamination and thereby meet HACCP international's food safety criteria."
