Bathroom fan with humidity sensor

Quite high humidity in the bathroom in many cases can cause mold and insects in the room. To solve such a problem and prevent frequent and expensive repairs, a fan can help. And the best option for such a device to ensure air circulation in the bathroom is a fan that has a humidity sensor.

The bathroom fan can be controlled either manually or automatically. When controlled manually, the device has a switch. It will help save money, but is unable to change the intensity of the extractor and control the humidity.

A more advantageous solution can be called a fan that has a timer. With such a device, you don't have to wait for the bathroom to finish airing, but it still has the same disadvantages as the manual control.

The presence of a motion sensor in the fan ensures that the device turns on when a person enters the bathroom. However, this version of the fan is also incapable of changing its operation based on the conditions inside the room. In fact, the motion sensor is simply a substitute for the switch.

All the disadvantages of the previous methods of control are removed from the fan, which has a hydrostat - a humidity sensor that analyzes the saturation of the air in the bathroom with water vapor. Such a device will turn on only in conditions of increasing humidity in the room.

Other features of a fan with this sensor are:

• A design that is easy to install on both wall and ceiling vents.
• Water-resistant materials of the fan, as well as careful insulation of all electrical parts.
• A check valve that prevents dust and unpleasant odors from entering the duct shaft into the bathroom when the fan is stopped.

• The operation of the sensor fan is fully automated.
• Electricity will be more economical because the fan will only turn on when the sensor is triggered.

Many models are quite noisy.

Both the internal structure and the principle of operation of a fan with a humidity sensor are practically the same as those of traditional fans - when the electric motor is turned on, the blades start spinning, which sets the air in the room in motion.

However, a fundamental feature of bathroom fan models is the fact that such a device does not move the air inside this room, but is designed to bring it into the exhaust shaft. With the air in the duct gets suspended droplets of moisture, so as a result of the work of the fan is able to change the humidity in the bathroom.

A bathroom sensor fan can be:

• Axial. This kind of fan is chosen for the bathroom most often.
• Centrifugal. This type of fan is usually chosen when there are problems with the ventilation duct.

Some models of fans in addition to the humidity sensor and check valve are present:

• Timer. You can program the device to work for 2-30 minutes after the power is turned off.
• Motion sensor. By reacting to the movement of a person, this fan will start working automatically.
• Function of constant ventilation. It provides prolonged work of the fan in a small power mode.
• Backlight.
• Possibility to adjust capacity.
• The built-in clock.

In our market, the most common fans with a hydrostat from such companies:

• Soler & Palau. This Spanish brand offers low-noise models of Silent fans, which can be installed in any position, and also have a check valve. Devices are very popular in our country due to the unpretentiousness, reliability and average price category.
• Maico ECA Piano. Products from this brand are characterized by a stylish design, low power consumption and many additional options, but the high cost has a negative impact on the popularity of these fans.
• Elicent Elegance. Products of this brand refer to the budget. In addition to the humidity sensor and check valve in such fans there is a motor with bearings and a microprocessor.

The fan, equipped with a hydrostat, copes with its functions perfectly, if you choose such a device correctly.

Choosing such a fan, it is important to consider:

1. What power of the device is needed? To determine it, you need to know the volume of the bathroom, which is multiplied by 3-8 (this figure means the change of air in the room). In this case, the best choice will be a more powerful model.
2. Where is the ducting located and how is it recommended to install the fan? Many fans work both when installed on the wall and in the ceiling position, but during the purchase you should clarify where it is preferable to install a particular model.
3. What is the configuration of the selected fan? The hydrostat in it can be built in (both room and channel) or purchased and connected separately.

If you identify a clog, it should be removed either by yourself or with the help of a specialist. And only then proceed to the installation of the fan. In addition, you should ensure air flow into the bathroom, which is easily achieved by a small gap under the door of the room.

To attach the fan housing will help you dowels or special adhesive. After installation, the fan is connected to the network through a conventional socket, switch, junction box or from the lamp, and then install the external grille.
