Ventilation devices ensure efficient air exchange in living spaces even with tightly closed windows. The variety of air vents available on the market allows you to flexibly adapt the solution to individual needs.

Air vents are installed at the top of the window. External air flows above the occupants’ zone, avoiding unpleasant drafts.

Depending on their operation, we distinguish:

• Hygro-controlled vents – automatically controlled; the amount of air supplied depends on the humidity inside the room. The higher the humidity, the more air is supplied. This means that depending on the time of day, the amount of incoming air changes. The controlling sensor is a polyamide strip bundle. It is possible to close the damper, limiting airflow to a minimum.

• Pressure-controlled vents – self-regulating; the amount of air supplied depends on the pressure difference between the outside and inside of the room. Up to the level where the vent reaches maximum performance. Further increase causes the flaps to tilt, reducing airflow, e.g., during strong wind gusts. The damper can be closed, limiting airflow to a minimum.

• Manual vents – the user manually adjusts the airflow by opening/closing the damper.

Lack of proper room ventilation causes:

• condensation on window surfaces,
• humidity in the room, which promotes mold and fungi,
• poor well-being (headaches, upper respiratory diseases, allergies, etc.),
• unpleasant odors,
• condensation of toxic substances emitted by furniture and finishing materials,
• insufficient air for fuel combustion in gas heaters, fireplaces, etc.
