Hand dryer forced air choice
Features and benefits of hand-forced air dryer
The hand dryer forced air has made an important appearance for 2 years in the market of hand drying. The hand-forced air dryer is characterized by a very high air speed allowing drying between 10 to 12 seconds depending on the models. It is this speed that helps to remove moisture from the hands, usually by gravity at the bottom of the device. Compared to electric hot-air hand dryers, it is not the heating of hands that dries hands but the powerful breath of air close to 300 km / h on average .
Some hand-forced air dryers still have a heating cell to pulse hot air.
The main attraction of forced air hand dryers and its very low cost and very short drying time compared to traditional dry hands and especially paper towels.
Nevertheless hygienically, the drying of hands with paper towel remains the reference.

When buying a hand dryer forced air must already check the presence of a HEPA filter or not. Indeed, this filtration allows filtration by eliminating up to 99.997% of bacteria .
Some hand dryers do not have a water tank (which comes from drying) and therefore the water falls directly to the ground. This involves a tedious cleaning and especially a poor sanitary condition.
A hand-held air dryer is also characterized by its IP rating and insulation . There are Class I devices that require grounding and some Class II devices that do not require it.
On the other hand there is a common point and that can be annoying in certain cramped premises which is the noise level.
He is sure that compared to a classic model and even more to a paper towel dispenser, it will not be the highlight of a forced air device.
The different types of hand-forced air dryers

The most widespread and historically successful model of forced air models and the so-called "vertical" model.
Nevertheless, since then, the designs and developments to perfectly adapt the model to the local and / or the use have been validated.
Thus, there are now compact models thus making it possible to overcome congestion problems, models with limited power to favor silence.
Indeed the weak point of vertical models that represent a large part of the current proposal on the market is its congestion sometimes unsuitable with the local.
