Features and benefits of the forced air hand dryer
The forced air hand dryer has made an important appearance for 2 years on the hand drying market. The forced air hand dryer is characterized by a very high air speed allowing drying between 10 to 12 seconds depending on the model. It is this speed which contributes to evacuate the humidity of the hands in general by gravity in the bottom of the device. Compared to electric hot air hand dryers, it is therefore not hand heating that dries hands but the powerful breath of air close to 300 km / h on average .
Some forced air hand dryers still have a heating cell to pulsate hot air.
The main attraction of the forced air hand dryer and its very low cost price and its very short drying time compared to traditional hand dryers and especially paper towels.
However, from a hygienic point of view, hand drying with paper towels remains the benchmark.

Models of air pulse hand dryers
When purchasing a forced air hand dryer, you must already check whether or not there is a HEPA filter . In fact, this filtration allows filtration by eliminating up to 99.997% of bacteria .
Some hand dryers do not have a water recovery tank (which comes from drying) and therefore the water falls directly on the ground. This implies a tedious cleaning and especially a poor state of sanitary facilities.
An air pulse hand dryer is also characterized by its IP protection index and its insulation . There are thus devices in class I which requires an earthing and some in class II which does not require it.
On the other hand there is a common point and which can be annoying in certain confined spaces which is the noise level.
It is certain that compared to a classic model and even more to a paper towel dispenser, this will not be the strong point of a forced air device.
The different types of forced air hand dryers
The most widespread and historically successful model of forced air models and the so-called "vertical" model.
However, since then, the designs and developments to perfectly adapt the model to the room and / or use have been validated.
Thus there are now compact models allowing to overcome the problems of space, models with limited power to favor silence.
Indeed, the weak point of the vertical models which represent a large part of the current offer on the market is its size, which is sometimes unsuitable for the local.
