The invention of the Airblade technology by Dyson: Technology for business provided an efficient alternative for drying hands in commercial washrooms worldwide. Dyson Airblade Tap hand dryers replaced the traditional paper towel system as well as poor performing electric hand dryers.

However, water dripping on the washroom floor remained a concern with users moving with wet hands to the hand drying area. The excessive sound of the hand dryer was another issue.

Keeping these challenges in mind, Dyson engineers set out to re-engineer the existing Dyson Airblade Tap hand dryer, with key objectives being to reduce the noise as well as maintain a fast dry time while minimising the wet floor problem.

The new Dyson Airblade Wash+Dry hand dryer combines a tap, and a hand dryer that dries hands in 14 seconds with HEPA-filtered air – all in a single touchless unit. The multi-function design helps to save space in the washroom and reduces the problem of water dripping on the floor.

Up to 39% quieter

Dyson engineers retuned the Dyson digital motor V4, which powers all Dyson Airblade hand dryers. The retuned 1000W motor draws in less air overall, reducing the sound generated by turbulence, and air moving quickly through narrow spaces. Key enhancements also include optimised 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; re-engineered air apertures shaped to help reduce the sound associated with high pressure air mixing with lower pressure ambient air; and a Helmholtz cavity inside the motor bucket cancelling out high-pitched motor tones and improving sound quality.

Lower CO2 emissions

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% less CO2 than paper towels and a few other hand dryer models in the market.

Uses 52% less water

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

Dyson Airblade Wash+Dry hand dryers

Available in Short, Tall and Wall variants, Dyson Airblade hand dryers feature HEPA filters that capture 99.95% of particles the size of bacteria (0.3 microns) from the washroom air.

The new Dyson Airblade Wash+Dry hand dryer comes with a 5-year guarantee and is certified by Quiet Mark, tested and approved by The Noise Abatement Society.
