An electric hand dryer is a device that you have definitely seen in the restroom of a shopping center, cafe or train. This device can easily replace a regular towel or wipes for wiping hands. Characteristics and dimensions of dryers may vary depending on the manufacturer and purpose. Consider the main functions and capabilities of dryers, as well as the top 5 best modern models.
What is a hand dryer
Before choosing a hand dryer, you need to understand what it is, how it works and how it works. This is an electrical appliance that can be connected to any network. In most cases, the dryer is hung on the walls near the sink.
The principle of operation is to blow the palms under a stream of warm air. This drying method is the most hygienic as there is no direct contact with the appliance. Using the hand dryer completely complies with current sanitary standards. That is why the devices are installed in crowded places: from schools and hospitals to airports and shops. Installing the device is quite simple, installation does not take much time and does not require specific skills.
Principle of operation
The operation of an automatic hand dryer is very simple. There are only two activation options:
- a sensor that is triggered by non-contact swiping along the activation line;
- button models.
In the case of an infrared sensor, it is enough to move your palm near the hole from which heated air is supplied. When the device is turned on, a jet of hot air is blown out of the hole under pressure. You can dry your palms in about 10-15 seconds.
Important! Manufacturers provide the ability to customize settings. You can choose the temperature and intensity of blowing. Some cases have a timer that allows you to set the operating time yourself. After the set time has elapsed, the dryer will turn off.
Most of all hand dryer interior It looks like a normal household hair dryer. Inside the case is a classic cooler, but its dimensions may vary. The heating element passes air through itself, blowing it into the nozzle. Of the electronics in the dryer, there is an activator, a sensor or a button. The material and shape of the body can vary significantly.
Types of dryers
Hand dryers fall into three categories.
- Classic. These are the most common dryer models equipped with mechanical or infrared switching. The body is made of plastic or metal. Drying occurs due to intensive blowing with hot air. Appearance of the device differs depending on the manufacturer and destination. Most of all, these dryers are suitable for everyday use at home. Classic models are found in common areas under video surveillance.
- High-speed. Here, the drying of the palms is carried out by means of a rapid supply of air. The air itself does not get very hot. Moisture from the palms does not evaporate, but is blown away under pressure. The flowing drops are collected in a specially designed tank, which has an outlet to the sewer. The dimensions of high-speed dryers are somewhat larger than traditional ones. This is due to the size of the fan installed in them. Also, high-speed dryers produce significantly more noise.
- Anti-vandal. The name of the category speaks for itself. The anti-divandal model is designed taking into account operation in unguarded places. In such devices, a high margin of safety is laid. Dryers are often found in common areas that are not equipped with a permanent monitoring system.

Important! According to the installation option, wall models prevail, although floor models are occasionally found.
How to choose a hand dryer
To choose the most suitable electric towel (sometimes called a conventional dryer), be guided by the following criteria.
Of course, power is one of the most significant selection criteria. It depends on him how effective the dryer will be.
According to the power of the model, it is assumed conditionally divided into 3 categories:
The powerful dryer has high efficiency: The heating element consumes up to 90% of the maximum motor output. All these parameters are displayed on the box with the device or in the technical data sheet of the product.
Important! On expensive models there is an adjustment of the blowing power level. A dryer with this feature is more convenient in everyday use.
The lower the power level, the more economical the appliance will be. But we must not forget that along with the power, its efficiency also decreases. Most users opt for medium and high power dryers. Models with a high airflow rate can harm the skin of the hands, so they are not suitable for everyone.
Activation of work with the help of a button is gradually being replaced by a non-contact one. Professional models are equipped with infrared sensors almost without exception.
Important! The main reason for the mass refusal of manufacturers from buttons is compliance with hygiene standards. During the day, hundreds of people can touch the button, as a result, many microorganisms and pathogenic bacteria will accumulate on it.
A common problem with push-button dryers is moisture ingress. Regular pressing on the activation mechanism leads to a gradual pushing of the button and an early failure. Such dryers require more frequent maintenance. But push-button models have a significant advantage: they do not turn on on their own.
Dryers are the most common among non-contact models. with infrared sensor. It is enough to run a wet palm along the activation line, and the device automatically turns on. As a result, there is no tactile contact, the surface of the palm remains clean, hygiene standards are observed. In some models, the user puts his hands in a special compartment where the blowing takes place (immersion dryer), in all other cases, the air is blown out of the nozzle located on the bottom of the case.
When hand drying is completed, the user simply moves their hands away and the appliance turns itself off. The disadvantage of such a dryer is quite a large number of false positives. A fly flying along the trigger line is enough – and the sensor will give a command to start. The result is increased electricity consumption. You can try to optimize the installation location, but this will not be an absolute guarantee against false positives.
There are 2 body options: plastic (budget models) and metal (it is much more expensive). Dryers with a plastic body are inexpensive, but subject to rapid wear. The thickness of the plastic may vary, depending on the specifications.
Advice! When choosing, it is recommended to pay attention to the absence of backlash, cracks, loose parts.
Sometimes the manufacturer decorates the plastic case in metallic color. Most often this is done in order to give a resemblance to a more expensive material of manufacture. It is quite problematic to distinguish such models visually. The strongest plastic material is polypropylene and polycarbonate.
Metal dryers are made of two grades of iron. Stainless steel lasts longer but costs more. Anodized aluminum is more affordable, but less durable. Anti-vandal options are made of alloys that exclude the possibility of crushing, scratching the body or causing other damage to it.
This indicator is tied to the power of the dryer. High-speed models dry your palms with ease in 10 seconds. Dryers of average power will cope with the task, on average, in 20 seconds. Budget options may take 30 seconds or more to dry completely.
The more powerful the fan and heating element, the more noise the machine makes. However, in expensive dryers, the case has some degree of sound insulation. In public places, especially where it is loud (airports, music clubs), this criterion is not so significant. However, in an office environment, a loud dryer can attract undue attention.
The most important attribute of any electrical appliance. Hand dryers can be equipped with protected case, masking the wire going to the outlet. Also note that if the unit is installed in a home with small children, the installation height of the hand dryer must be appropriate.
Important! If the body is made of solid plastic, make sure that the material is not combustible. With metal models, attention should be paid to the degree of waterproofing of all electronics.
Industrial models designed for a large flow of people are equipped with a powerful engine. Accordingly, the sound emitted by them is very high. Such dryers should not be installed in places designed for quiet pastime (in cafes, restaurants, offices).
For home use, models with the lowest sound parameters are recommended. Any false alarm, especially at night, can lead to stress or fear, wake up children.
Some models may be equipped with additional features. Most often it is a blower power regulator and an adjustable timer. But some manufacturers equip their models with additional antibacterial optionssuch as a UV lamp. The use of such a dryer not only eliminates the ingress of pathogenic bacteria on the outer layer of the epidermis, but also additionally sanitizes the treated areas. Touch control of temperature and airflow intensity – additional options found only in expensive models.
