Dyson Airblade Tap hand dryer explained - Official Dyson video
The Dyson Airblade Tap hand dryer washes and dries hands with no need to leave the sink. Infrared sensors pinpoint hand positions and release water from the tap stem. Once hands are wet and drying is requested, integrated circuitry computes the information and activates the latest Dyson digital motor, creating two high velocity sheets of air on the tap's branches. Unheated clean air is released to scrape water off hands leaving them dry in 12 seconds.
