CHICAGO—In 1907, paper towels were introduced to washrooms. The electric hand dryer made its first appearance in 1948. But both can be expensive, unhygienic, and harmful to the environment. In 2006, Dyson engineers put a century of poor performing hand drying methods to rest, with the invention of Airblade hand dryer technology.

But even with an efficient hand dryer, water dripping on the washroom floor can be a concern, as can excessive sound. With these challenges in mind, Dyson engineers set out to re-engineer the existing Dyson Airblade Tap hand dryer, to reduce loudness while maintaining a fast dry time. The result is the new Dyson Airblade Wash+Dry hand dryer—a single touchless unit that combines a tap and a hand dryer, drying hands in 14 seconds with HEPA-filtered air.

The multi-functional design helps to save space in the washroom and reduces the problem of water dripping on the floor as users move from a handwashing area to a separate drying station. And it’s now up to 39 percent quieter than its predecessor. Dyson engineers achieved this sound reduction by re-tuning the Dyson digital motor V4, which powers all Dyson Airblade hand dryers. The re-tuned 1000W motor draws in less air overall, reducing the sound generated by turbulence and air moving quickly through narrow spaces.

Re-engineered Air Apertures

Dyson engineers also optimized slot blade geometry, reducing the air apertures from 0.8mm to 0.55mm to maintain high air velocity at exit, despite the reduced volume of air passing through the machine. The re-engineered air apertures are also shaped to help reduce the sound associated with high pressure air mixing with lower pressure ambient air. Lastly, a Helmholtz cavity inside the motor bucket cancels out high-pitched motor tones and improves sound quality.

The new Dyson Airblade Wash+Dry hand dryer costs $34 a year to run, compared to its predecessor’s $48. Dyson Airblade hand dryers cost up to 76 percent less to run than other hand dryers, and up to 98 percent less than paper towels.

The new Dyson Airblade Wash+Dry hand dryer produces 3.6g of CO2 per dry, compared to its predecessor’s 4g. Dyson Airblade hand dryers produce up to 79 percent less CO2 than paper towels and some other hand dryers.

Slower Flow Rate

The new Dyson Airblade Wash+Dry hand dryer’s flow is 0.5 g/min (1.9 l/min) compared to its predecessor’s 1.0 g/min (4 l/min)vi. The water only activates when a user’s hands are underneath.

The new Dyson Airblade Wash+Dry hand dryer is available in Short, Tall and Wall variants. All Dyson Airblade hand dryers have HEPA filters that capture 99.97 percent of particles as small as 0.3 microns from the washroom air.

The new Dyson Airblade Wash+Dry hand dryer comes with a five-year limited warranty and is certified by Quiet Mark, tested and approved by The Noise Abatement Society.
