An electric hand dryer is a modern appliance that simultaneously heats and delivers air. In some cases, it is installed in public places - shopping centers, food networks, in large office buildings.
Types of Electric Hand Dryers
These devices differ in various parameters, for example:
- Type of performance. There are open and closed devices. The first of them is standard, and the second differs in the method of use - for drying hands, they must be placed in a special chamber. Closed-type devices are more expensive in cost and more difficult to maintain.
- Security. Each dryer has a different degree of protection and the principle of start-up. There are semi-automatic and automatic devices. In the first case, to start the user must press the power button. The second ones are equipped with a touch sensor; there is no need to touch the device. Automatic dryers are safer and more economical, because they are protected from overheating and excessive waste of electricity.
- The material of manufacture. Small office buildings and home use dryers with a plastic case, they are lightweight, inexpensive and easy to operate. In crowded places, it is recommended to install steel dryers. The latter have increased resistance to mechanical damage and are designed for a long service life.
The device device and preparation for work
Devices, for example, an electric hand dryer Ballu Bahd 2000DM, start automatically thanks to an optical sensor that, when a person approaches a certain distance, turns on the heating and the fan.
The response area is set at 8-15 centimeters from the lower grill. After 5-8 seconds, the device automatically turns off.
For the most comfortable use, it is recommended to correctly determine the installation location. The appliance must be located at least 50 cm from the edge of the sink to prevent splashing during hand washing. The height from the floor should be at least 120 cm, from the side wall - 10 cm.
Before installation, make mounting markings and drill holes. Next, a bracket is mounted on 4 screws.
Important! The dryer should fit snugly against the wall. The device is designed to connect to a 220-230 V network. The dryer is connected to a stationary network with a two-cavity outlet using a plug and cable (included in the package). The phase wire of the outlet is connected via a circuit breaker. There is no need to ground the device: it is completely electrical safe.
Immediately after installation, the dryer is ready for use. To use the device, it is enough to bring your hands to a distance of not more than 15 cm from the lower grill. At the end of the process, the dryer will automatically shut off.

Advantages of using dryers
The biggest advantage of wall-mounted electric hand dryers is the lack of the need for constant replacement of consumables (for example, dry towels, napkins). Also, these devices consume a small amount of electricity, are compact and convenient to use.
A significant drawback is the need for thorough maintenance and periodic cleaning. Installation of these devices is carried out only by qualified specialists. In crowded places, cleaning should be done at least once a month.
Maintenance
During operation, it is necessary to monitor the condition of the suction openings - they should not be clogged or covered. An electric hand dryer does not require special care. Exterior surfaces should be regularly cleaned of dust and dirt. It is also necessary to monitor the cleanliness of the sensor lens, air duct grille and housing. A damp cloth and mild detergent are used to care for these surfaces. After cleaning, dry the appliance thoroughly.
Important! Internal surfaces may only be cleaned by a qualified professional. All surface care work is carried out with the power off. The use of abrasive and corrosive products is prohibited. It is also forbidden to spray water onto the dryer during operation and cleaning.
User reviews
Popular climate appliances have received many reviews from users. The main advantages are:
- stylish design;
- resistance to mechanical damage;
- powerful air flow;
- ideal angle for blowing hands (30 °);
- light weight and dimensions;
- low noise level;
- saving on the purchase of towels;
- hygiene;
- space saving at the installation site;
- the possibility of selection according to individual style parameters - a wide variety and color schemes will allow you to choose the most suitable option;
- low power consumption.
Important! Any dryer is made in a moisture resistant case and is completely safe. In order to avoid the entry of various bacteria into the mechanisms, cleaning filters are installed in the devices.
Do not forget about the noise level: it directly depends on the power. In public places, high noise does not affect staff performance. But if you plan to install the device in a living room, it is worth considering this parameter.
The disadvantage is overheating of the heating element with prolonged use, as well as the relatively high cost for use at home.
You can select and buy an electric hand dryer in St. Petersburg or another city in ordinary or online stores of household appliances. Depending on the required power and purpose, you can purchase the most profitable and affordable device.
