Hand dryer - How it works

Wow, are they trying to entertain me while I wait? All that text ...


How it works - we have achieved the best possible performance by using the available power supply & holding the air velocity to a level which will allow it to heat to the highest temperature near dry hands could stand on a warm day. This produces the dryest air giving the maximum rate of evaporation. Why it varies - because of the initial temperature & humidity of the air & the amount of moisture on your hands.
