High speed hand air dryers

High speed hand air dryers are products that are specifically designed to dry hands by moving air in such a manner that the water is physically removed or evaporated.

High speed hand air dryers are products that are specifically designed to dry hands by moving air in such a manner that the water is physically removed or evaporated. High speed warm air dryers use jets of warmed air driven at higher speeds than the conventional dryers. Hands can be held beneath the dryer or inserted into an opening. A more powerful motor is used to increase air speeds to around 50- 80 m/s, which allows drying times to be reduced to around 10-15 seconds. Energy is thus saved through reduced drying times and heating requirements. High speed ambient air dryers use ambient air at high speeds so that water is physically removed from the hands. Hands can be held beneath the dryer, or inserted into an opening and air is directed from both sides. The motor used to drive the air is more powerful than for the warm air dryers so air speeds are greater, and no heater is required. Typical drying times are around 10-15 seconds.
