by Shane Henson — October 11, 2013—Drying hands using a high-speed hand dryer reportedly just became much less noisy with the introduction of the Dyson Airblade dB hand dryer.
According to Dyson, engineers have reengineered the apertures of the Dyson Airblade hand dryer to reduce air turbulence. Two sheets of high-velocity unheated air travel through up to 0.4mm scallop-shaped apertures, quickly scraping water from hands like a windshield windscreen wiper, leaving them fully dry. The scallop design increases the distance travelled by the two sheets of air before they collide. An overhanging lip on the front aperture alters the angle of the air exiting the machine, further reducing the sound made when the sheets collide.
As a result of these modifications, the new product is 50 percent quieter when compared to the Original Dyson Airblade hand dryer and dries hands in just 12 seconds, the company said.
According to the Dyson, its Airblade dB hand dryer is also 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 traffic, high-usage locations where vandalism can be an issue. And because it uses filtered sheets of 420 mph air to dry hands, there is no heating element prone to wear and failure, the company adds.
Lastly, the hand dryer is also more hygienic than others on the market, says Dyson, as it comes equipped with a HEPA filter to remove 99.97 percent of bacteria at 0.3 microns from the air used to dry hands.
