The fast and energy-saving hand dryer with HEPA filter. The Dyson Airblade 9kJ hand dryer consumes 9.1 kilojoules per use according to the manufacturer, with operating costs of only 35 CHF per year in Eco mode, and produces up to 87% less CO2 than paper towels. The powerful motor spins at 75,000 RPM and moves 23 liters of air per second - drying hands in 10 seconds in Max mode. Two curved, 0.45 mm narrow slots create air streams with speeds of 624 km/h that follow the contours of your hands, removing water more quickly. Unlike some other hand dryers, Dyson Airblade hand dryers feature HEPA filters that remove 99.95% of particles, including bacteria and viruses.
