Are hand dryers fast?
In the past, hand dryers had a reputation for working slowly and being inefficient, leading to longer bathroom breaks, and high energy bills. Old fashioned evaporative dryers were noisy and often a less hygienic choice, however modern jet hand dryers such as the Mitsubishi Electric Wave range work much faster, use less energy and result in cleaner hands.
Drying Times for Hand Dryers
The design of traditional warm air hand dryers means that it can take an average of 35 seconds to fully dry the user’s hands.
Evaporative hand dryers work by blowing slow moving air over a heating element and then out through a nozzle. The user rubs their hands together in the airflow to spread the moisture over their skin so that it can evaporate.
This method of drying hands is slow because the air temperature needs to be carefully controlled – not too warm to damage the skin, and not too cool to be ineffective.
Over time, as the components of an evaporative hand dryer age, the air speed can slow down and as a result the air is not heated as effectively which contributes to longer usage times.
