How to choose a hand dryer?
Hand dryers are often used in bathrooms, bathrooms of public premises, offices, restaurants, cafes ... and very rarely in residential areas. In fact, for this they were designed to help people dry their hands in places where isolation from each other is extremely important. Bacteria, germs, all this is easily transported through a towel, so there are really very few alternatives. Or paper towels, or a hand dryer. And if you started reading this article, you just need to dry.
So, how to choose a hand dryer? First of all, answer the questions, where will you use it, what is the cross-sectional capacity, what contingent visits the bathroom? All this is important and from this we will begin.
We start with the evaluation of the bathroom.
This is the first and most important question, it is he who will indicate what further characteristics to choose. Think about how many people per hour or day will use the restroom and in particular the hand dryer? What contingent will be there, is there a chance that someone will want to tear off the device or just stick a cigarette in it? Do I need additional features other than hand drying? How much should the dryer be safe? Thought? And now to the specifics!
Power hand dryers.
Most devices begin to choose exactly with the evaluation of power, here is the same. The more powerful the dryer, the faster it will dry your hands. But the more powerful does not mean that it is better. In addition, the power of the dryer, it is often the addition of the power of the fan and heater, and they may differ. As a result, we can get a dryer that blows too much, but warms a little and vice versa, it blows badly, and the temperature almost burns hands. It is important to find an average, hand-friendly option. And do not forget to take into account that in a beauty salon, for example, no one is in a hurry and it’s better to dry your hands there longer so as not to overdry them. Similarly, in the restroom of the metro, it is important to dry your hands soon due to the large terrain and low speed will create a queue for this device. Here it is already important not to dry the hands so much as to manage to dry them.
The contingent and the daily volume of users - these are the main criteria for choosing a hand dryer.
The capacity of hand dryers varies from 0, 8 to 2.6 kW, air speed from 70 to 300 m3 / hour and above. It happens that the characteristics indicate the rate of blowing. But it is difficult to compare power with any of the two characteristics. Different nozzles give out air differently, some heat more, others blow worse. Therefore, when choosing power, we are guided by what stream of people the chosen hand dryer is intended for. But most importantly, we estimate such a parameter as “drying time”. He will tell a lot more than the power of the device.
By the way, some dryers do not heat the air, but simply blow, blowing drops at a high speed (more correctly, water molecules). Such hand dryers just do not dry out the skin, however, they are much more expensive.
The material of the dryer body.
There are hand dryers with a plastic body, there is a metal. Choose is relatively vandalism features. Metal are considered to be "anti-vandal", but the characteristics must necessarily have such a characteristic, because apart from the material, the assembly is important so that nothing sticks out, it does not attract the attention to tear something and the whole structure is securely fastened to the wall. In the case of a search for dryers for the office, it is not so important, but in educational institutions, discos, public toilets, there is only metal. True, there are "anti-vandal" counterparts and of heat-resistant impact-resistant plastic, the so-called melamine. These dryers are considered even better than metal, since such plastic cannot be spoiled by fire from a cigarette or lighter, and a trace will remain on the painted metal.
The inclusion of the drying type.
Now few dryers are turned on with the help of a button, most of them are a sensor, which is very correct, because the button is an additional opportunity to transmit all sorts of viruses to each other. And so, we brought our hands closer - the dryer started working, they moved it away - it stopped, and there is no need to touch anything. In fact, there is almost nothing to choose, except that sensitivity should be discussed with the store managers. For a small bathroom or with a large terrain, too-configured motion sensor will turn on the device constantly, even if it does not dry hands. This will lead to waste of electricity, and to a faster drying out.
Safety while drying hands.
Among other things, it is important to understand that all the bathrooms have high humidity, and the hands that reach for the device are always wet, while the dryer is an electrical appliance. So the protection class here is an extremely important factor, otherwise you will have to pay more than money. The moisture protection class in the hand dryer must be at least IPX1 and the more, the better. It also depends on where you will install the device. For school, you can buy a dryer with a moisture protection class and IPX5. All these moments are more correct to check with the guests, which set the standards for such devices precisely for your type of room.
The noise level of hand dryers.
If this is a public place, for example, a bathroom at an airport, train station or subway, where it is noisy, you can ignore this parameter. But if it is a school, a quiet restaurant, an office with thin partitions, etc., then the noise level of a hand dryer is better to choose less. True, such dryers are very expensive and, perhaps, it will be more practical to soundproof the room than to buy a quiet dryer. At the same time, it will not be too quiet for big money either.
Air filtration.
Not many hand dryers have their own filters, but this is very important. Imagine if the dryer does not filter the air, then all the bacteria will accumulate on the hands that have just been washed. So think, whether or not this parameter is important for you, your employee and clients.
Trivia.
There are dryers, where, together with the ability to dry your hands, you can dry your head (the nozzle can be sent to any place in the body). For the restroom at the disco is a very good point. Similarly, there is a dryer with the ability to immediately dispense liquid soap, before you wash your hands. There are alternatives and sometimes they provide savings, although they are worth more.
Warranty on the device for drying hands.
By choosing an expensive hand dryer, you can get a very impressive guarantee. It is 4 or 5 years, which indicates the quality of the device and durability. But the right thing to buy such devices in offices, restaurants, cafes, medical facilities. When the device is installed in a night bar, or at the station, even the most expensive one can serve no more than a year. And most importantly, the guarantee in this case is completely canceled. It only works in those places where there is no risk of damage to the device, and during vandalism, no one will repair it for free. Therefore, in public places it is better to buy reliable and inexpensive dryers, and expensive ones only in places with an intelligent contingent.
Yes, it is not difficult to choose a hand dryer if you correctly assess the room and the people who will use it in the future. Start from here see more info of click here.
