Bathrooms are rooms that should be very well ventilated. This is due to the large amount of various pollutants in the air and the moisture that forms under the influence of water vapor. Too many of these factors can cause unpleasant odors and problems with drying towels, as well as the formation of mold on the surface of the walls. To prevent this from happening, we should purchase a bathroom fan.
How does a bathroom fan work?
The bathroom fan is a device mounted on the top of the side walls or on the ceiling. It is essential that the equipment is located at the inlet of the ventilation duct. It is also known as a compressor and is used to draw in used air from the room. This is possible thanks to gravity, which is assisted by the negative pressure that forms inside them. The operation of the equipment is based on the movement of air. In order for it to function properly, an increase in static pressure is necessary, which must be greater on the suction side than on the suction side. The best bathroom fanit is able to neutralize unpleasant odors and attract particles of dust and dust. Some devices available on the market are also equipped with the function of adjusting the intensity of work. It allows you to increase or decrease the efficiency of work depending on the needs and preferences of the user. In stores, we can buy equipment that is self-propelled or one that requires electricity. We can find it in a set with air conditioning, as well as other household appliances. Such models are able to work constantly. In their case, it is also possible to regulate the speed. This is useful when you sense excessive smoke or a very intense, unpleasant odor.
The use of fans
Fans are devices that are currently used in most houses and apartments. They are mounted in openings in the walls that have access to ventilation ducts. Some of the models currently on the market are powered by electricity. Thanks to this, each user can regulate the operation of the fan, as well as install a ventilation system in the house, which will be used to turn on and off the devices connected to it. In the case of this type of equipment, the factors that stimulate them to work are: Excess moisture, pollution, smoke or smog.
Fans are also installed in public utility buildings as well as in hotels and restaurants. In such places, they are usually combined with lighting to form a single system. Then, when entering the room and turning on the light, ventilation is also activated. As a result, the amount of electricity consumed is reduced and operating costs are lower. The solution is most often used in bathrooms to prevent the persistence of water vapor in them, and thus counteract the appearance of mold and fungus.
Features of bathroom fans
The fans available for sale have different functions. There are six basic possibilities of operation that are found in this type of devices. Those are:
Standard version – such models do not have any additional function. They can be activated with a separate switch located in the wall. They are often connected to a room light switch.
With timer – these are devices with a time delay function. After switching off, they continue to work for some time. As a result, after the user leaves the bathroom, the air is still cleaned of all kinds of contamination. This type of compressor requires a three-wire connection (neutral, solid, intermittent). Currently, we can also find models equipped with an automatic timer on sale. Their work is based on the fact that they turn on only after several seconds from the moment the light is turned on. If we leave the bathroom during this time, the timer will not start the fan. If the light is not turned off, the device will turn on and will work for some time after turning it off.
Z czujnikiem wilgoci – to modele wyposażone w funkcję samoczynnego uruchamiania. Ich praca rozpoczyna się w momencie wykrycia w pomieszczeniu zwiększonego poziomu wilgoci. Urządzenia mają także timer, czyli opóźnienie czasowe. Większość dostępnych na rynku wentylatorów z higrostatem wymaga podłączenia trzyżyłowego (żyła neutralna, faza stała, faza przerywana). Sprzęt uruchamia się samoistnie, jednak jest także możliwość podłączenia go do włącznika w ścianie. Niektóre modele można włączyć ręcznym włącznikiem sznurkowym.
Z czujnikiem ruchu – wyposażone są w samoczynny czujnik, który uruchamia urządzenie w momencie wykrycia ruchu. Wentylatory pracują do czasu wykrywania ruchu. Kiedy przestaną go wyczuwać, pracują jeszcze przez jakiś czas, a następnie się wyłączają.
With light sensor – models that are activated automatically when bright light is detected. They are intended mainly for rooms where there is no window. The fans start their work when, for example, we turn on the light. After the bathroom is darkened again, it continues to work for some time, and then switches itself off.
With safe voltage (12 V) – devices in the standard version that can be installed in very humid places. It is necessary to use a transformer for their assembly.
