Dyson AirKnife (Air Knife) Technology Powers The Dyson Airblade Hand Dryer
Air knives are high-intensity sheets of airflow often used in industry to separate materials. Dyson applied this technology to the Airblade hand dryer. The Air Knife technology allows for a rapid, uniform airflow acting as an invisible wiper blade, literally scraping water from hands. With a 400mph airflow, the Dyson Airblade™ hand dryer takes just twelve seconds to dry hands and uses less energy than warm air hand dryers. But it’s only possible because of the Dyson digital motor and Air Knife Technology.
