The Airblade technology in the Dyson Airblade V works differently. Every second, 20 liters are blown out via the HEPA filter, and this is done through openings with a width of 0.55 mm. This creates air currents at a speed of 690 km / h, which hygienically, your hands dry in just 12 seconds, Dyson Airblade lade produces up to 80% less CO2 than any other hand dryer and up to 81% less than disposable paper towels.The digital motor is precisely set to 1000 W, so less air is sucked through the machine. This results in less turbulence and therefore also less noise. The propeller and internal diffuser have also been redesigned to achieve airflows that are as quiet as possible, and the air vents have been reduced from 0.8 mm to 0.55 mm so that the air velocity remains the same while the volume decreases.Noise test documents that the Dyson Airblade V hand dryer is 35% quieter than its predecessor thanks to the reprogrammed digital engine technology and the precise air currents. The Noise Abatement Society has tested, approved and awarded the Dyson Airblade V Quiet Mark for its decibel level as well as its sound quality.The Dyson Airblade V hand dryer has a slim, compact profile and protrudes only 10 cm from the wall, which means that it takes up less space in the toilet. The back panel is easy to install, so you can easily install, maintain and replace it yourself.
