    Dyson Airblade Tap hand dryer washes and dries at the sink

    Dyson: Technology for business

    Dyson  introduces a new tap fitting that washes and dries hands at the sink.

    The Dyson Airblade Tap hand dryer features infrared sensors that pinpoint hand positions and release water from the tap stem. Once the washing is completed 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.

    Using Airblade technology, the Dyson Airblade Tap hand dryer sends sheets of unheated filtered air towards the hands literally scraping them dry.

    James Dyson explains that Dyson engineers have employed laser cutting techniques to manipulate marine grade steel, creating an intuitive high performance tap with two branches, and channelling high velocity air to literally scrape water from the hands and into the sink, keeping the floor dry.

    Key features of Dyson Airblade Tap hand dryers:

    Dyson digital motor

    The Dyson Airblade Tap hand dryer is powered by the latest Dyson digital motor, a power dense brushless DC motor utilising a bonded magnet encased in a carbon fibre sleeve. One of the world’s smallest and fully integrated 1600W motors, the motor uses digital pulse technology to accelerate from 0 to 90,000rpm in less than 0.7 seconds.

    HEPA filter

    The Dyson Airblade hand dryer passes washroom air through a HEPA filter to remove 99.9% of bacteria before it’s blown onto washed hands.

    Motor bucket design

    Key components including the motor are housed in a discrete package under the sink. The motor bucket is backed by over 2,240 hours of design work by Dyson engineers who worked hard to contain noise, introducing springs to reduce vibration, acoustic foams to absorb noise and expansion chambers to improve sound quality.

    Helmholtz silencers

    Six Dyson-designed Helmholtz silencers combine to absorb tonal frequencies and reduce the motor tone. The first harmonic of the motor tone, plus the high pitch noise made by the impeller have all been contained and made almost inaudible to the human ear.

    Sensor operation

    Independent infrared sensors allow the user to have as much water and air as they need. An aerator mixes the water and dispenses water across the hands to reduce the volume of water used and the flow rate of water is controlled by motion detection.

    Materials

    Made from 304 stainless steel, an anti-corrosion steel grade used for the construction of boats, Dyson Airblade Tap hand dryer is manufactured using a specialised laser cutter capable of cutting through tough steel with laser precision, which means there are almost no joining lines and the air, water and electrics are contained in a smooth package at the sink.
