High-speed, energy-efficient hand dryers have become an industry standard today, thanks in large part to better technologies and improved performance. Modern dryers boast 10-15-second dry times and use up to 90 % less electricity than traditional models. Importantly, 10 seconds is also the average time that it takes a person to dry his/her hands with paper towels, so hand dryers today have closed the gap.
Efficient hand dryers offer considerable savings over paper towel dispenser and can pay back the initial investment within a few months.
