Dyson Airblade 9kJ Hand Dryer

  • The Dyson Airblade 9kJ hand dryer uses 9.1 kilojoules of energy per dry in Eco mode. With a fleece-lined glass fibre HEPA filter to capture 99.95% of particles1, including bacteria and viruses, from the washroom air. The quietest2 Dyson Airblade™ hand dryer features silencers made from open-cell foam and perforated discs, reducing noise as airflow passes through the motor. The Dyson digital motor spins up to 75,000 times a minute3, powering two 0.45 mm curved apertures. Together they create 388 mph3 sheets of air that follow the contours of your hands, removing water quickly and hygienically.

    3Measured in Max mode

    • Curved Blade™ design - Sheets of air travelling at 388 mph1 follow the contours of your hands.
    • Powered by the Dyson digital motor V4 - The Dyson digital motor spins at 75,000rpm to shift 23 litres of air a second, for a 10-second dry time in Max mode2.
    • Low energy - Efficient aerodynamics means the Dyson digital motor draws 85% less energy than a warm air hand dryer3.
    • The quietest Dyson Airblade™ hand dryer yet - Straight line configuration allows for simpler airflow paths which reduces air turbulence, meaning less noise and less energy consumption.
    • Small carbon footprint - Produces up to 85% less3 CO2 than paper towels and up to 85% less than other hand dryers.
    • Hygienically dries hands with clean air. HEPA filter captures 99.95% of particles4, including bacteria and viruses.
    • Costs just £19 per year to run in Eco mode - Up to 99% less expensive to run than paper towels and up to 86% less than warm air hand dryers5.
    • Touch-free operation - ‘Time of flight’ sensors accurately detect hands in 0.25 seconds to activate air without wasting energy.
    • Create space in your washroom - Slim and compact at just 100mm deep, no recessing required.
    • Easy to clean and service - Stainless steel finish. Safe electrical disconnect

    1Measured in Max mode

    2Dry time determined for Max mode using Dyson test method 769 based on NSF P335 to a measurement of 0.1g residual moisture.

    3The environmental impact of electrical appliances and paper towels was measured by the Carbon Trust. The calculations were produced using the software Footprint Expert Pro, based on product use over 5 years and using weighted averages of individual countries of use. Dry times for product were evaluated using DTM 769.
