by Brianna Crandall — October 26, 2016 — Some quiet hand dryers use weak motors to keep noise levels low. But that can increase dry time, forcing some washroom users to give up and leave with damp hands — increasing the spread of bacteria by up to 1,000 times, according to global technology company Dyson. On the other hand, fast hand dryers use bigger motors to improve dry times, but can generate high noise levels as a result. That can be disruptive in spaces where people work or relax.
With the latest development in its Airblade technology, Dyson engineers have invented a hand dryer that does not have to compromise — on speed, hygiene or sound. They achieved this by combining expertise in aerodynamics, acoustics and motors to re-work the technology and refine airflow paths through the machine in order to reduce turbulence. Putting into practice Dyson’s philosophy of “doing more with less,” engineers created a machine that reportedly also costs 28% less to run compared to its predecessor and up to 98% less than paper towels .
The Dyson Airblade V hygienic hand dryer is now 30% quieter and costs 28% less to run than its predecessor, is proven to be as hygienic as paper towels, and is easier on the environment.
30% quieter
Acoustic testing shows that the new Dyson Airblade V hygienic hand dryer is now 30% quieter than its predecessor. This has been achieved through the use of: precision air apertures to maintain air velocity while reducing turbulence; an aerodynamic motor package to enable sound-optimized airflow paths through the motor; and a reprogrammed Dyson digital motor V4: precisely tuned to 1000W (up to 1400W previously) to draw less air overall through the machine — reducing sound from turbulence, while maintaining a fast, hygienic drying time.
Certified by Quiet Mark
The Noise Abatement Society tested and approved the decibel levels and sound quality of the Dyson Airblade V hand dryer, awarding it the Quiet Mark. The Quiet Mark has been developed in response to public health concerns over the psycho-physiological effects of excessive or invasive sound produced by appliances.
Hygienic hand dryer
The Dyson Airblade hygienic hand dryer uses HEPA filters that capture up to 99.97% of particles the size of bacteria and viruses as small as 0.3 microns from the washroom air. So, hands are dried in 12 seconds using cleaner air, not dirty air. The machine contains an antibacterial additive that can help prevent the growth of bacteria on its external surfaces. It has been proven to be as hygienic as paper towels through research conducted by several universities and published in the Journal of Applied Microbiology, and is the only hand dryer globally certified as hygienic by NSF.
Low running costs
Dyson Airblade hand dryers cost up to 80% less to run than some other hand dryers, and up to 98% less than paper towels. This machine costs just $31 per year to run, while paper towels can cost up to $1,460 annually. It dries 24 pairs of hands for the price of a single paper towel. And compared to the original Dyson Airblade V hand dryer, it costs 28% less to run.
Lower impact on environment
Dyson Airblade hand dryers produce up to 79% less carbon dioxide (CO2) than some other hand dryers and up to 76% less than paper towels. This machine produces just 2.4g of CO2 per dry, compared to the previous Dyson Airblade V hand dryer at 3.5g of CO2 per dry.
More room. Less hassle.
With a slim, compact profile that protrudes just four inches from the wall, the Dyson Airblade V hygienic hand dryer takes up less space in the washroom, with no recessing required. Its easy-mount backplate allows for self-service installation and maintenance.
