HAND DRYER OPTIONS



World Dryer Model A
 


Question:

Hand Dryer Expert,

We are looking for hand dryer options that do not involve paper towel dispensers. It is for a high end restaurant where noise disturbance to patrons in the dining room needs to be avoided. I was curious if there are any air dryers that are quiet enough for our needs? Some of the descriptions say ‘quiet operation’ or ‘less noise’ but we’d like to hear some examples if possible. Of course we would appreciate your thoughts if you know of any other options as well.

Thank you,
Dana

Answer

Dana,

As a rule of thumb, the faster the hand dryer, the louder it is. Therefore, you need to know that a quieter hand dryer will not be as effective as a louder hand dryer. However there are a lot of good quiet hand dryers on the market made by Excel Dryer, American Dryer and World Dryer.
We like the World Dryer Model A because it is a very durable, dryer with a 25 – 30 second dry time.  There are some others that are quieter, but they are also a little slower. 
 
You can see this video for a comparison of noise levels. Most of them are high speed hand dryers, which are too loud, but it also includes the Model A. 

The Excel Cast series hand dryers are fairly quiet. As are the American Dryer DR hand dryers.
 
Thanks, Hand Dryer Expert

SENSOR ACTIVATED HAND DRYERS





Question:

Hand Dryer Expert,

Hi there, I am writing re your Airforce Hand Dryer Model J-979 - will this unit shut off immediately when the person steps away from the unit or does it continue to run?
Thanks,

Tim


Answer:






Tim,

All automatic hand dryers, like the Airforce, are designed to stop running when the user removes his or her hands from them. The Airforce is designed with a 1 second delay so that it won't go off when you are still trying to use it.

Further information: If your hand dryer is running when hands are not present, we call that ghosting. This could be because of a faulty sensor, a bad electrical connection, or because there are reflections in the room. If the hand dryer is mounted too close to a the surface below it such as a counter (closer than about 14 inches, give or take) then it might be cycling because of the reflection off of the counter. If this is happening, first reset the hand dryer by turning off the circuit to the hand dryer. Some hand dryers have a sensor that can be adjusted to be more or less sensitive by turning a screw connected to the circuit board.
