Why install a household exhaust fan?
A household exhaust fan is an electrical device designed for the effective removal of humid air, regulation of indoor air exchange, and elimination of unpleasant odors.
These fans are typically installed in bathrooms, toilets, and kitchens—areas where builders have included ventilation shaft openings.
A logical question arises: why do you need a fan if air is already moving through natural ventilation? Let us explain.
Natural ventilation in apartment buildings can be problematic. Depending on weather conditions, as well as due to design flaws and other reasons, draught can be weak. In some cases, back-draught even occurs, where air from the ventilation shaft enters the room, bringing unpleasant odors with it.
A fan can help deal with all these problems.
Draught:
- It reliably removes air from the room, enhancing the draught.
- The fan can operate continuously or intermittently, for example, while the bathroom light is on.
- Some models feature a ventilation mode and can activate at set intervals to ventilate the room.
Back-draught:
- A running fan eliminates the possibility of back-draught.
- Even when the unit is not operating, air movement can be blocked using a back-draught shutter.
- Some fans come with a shutter pre-installed, while for others it can be purchased separately.
- There are also fans with automatic shutters, such as the AUTO from the VentEurope trademark.
- Its shutters open when the fan is turned on and close after it is turned off.
- When the fan is switched off, the airflow is completely blocked.
Humidity:
- By removing humid air from the room, the fan reduces the humidity level.
- Damp conditions promote the growth of mold and harmful bacteria.
- High humidity can also cause windows to fog up.
- A fan helps eliminate all of these issues.
It should be noted that the trademark’s product range includes fans with humidity sensors. They turn on automatically when the humidity level set by the user is exceeded.
