This hand dryer features everything from enhanced hand dryer hygiene to incredible energy efficiency. Featuring HEPA filters which work to trap 99.9% of airborne bacteria and viruses. Adjustable to ambient air temperature automatically, the 3D Smart Dry hand dryer generates warm air at a comfortable temperature in the colder months and reduces waste power in the summer by heating air unnecessarily. This intelligent heating hand dryer is ideal for minimising expenditure and excess energy use while still remaining efficient at a comfortable temperature. Using the ambient temperature of the room, the 3D Smart Dry produces enough heat to maintain a controlled, comfortable temperature.
