Window air inlet vents take care of proper ventilation inside a room. Air inlet vents are devices that supply air from the outside to the room.
Windows that are too air-tight prevent air exchange, as a result of which the air inside the room becomes stale and signs of fungus or mould may appear on the walls.
Owing to air inlet vents, there is a constant supply or fresh air, even when the windows are tightly closed.

A standard air inlet vent consists of two parts:
an inner part – the so-called controller – that controls the amount of air being supplied;
an outer part – the so-called hood – that protects against rainwater and insects;

Hygro-controlled air inlet vents:
These are automatic devices because they make autonomous decisions on the air flow rate.
In the case of hygro-controlled air inlet vents, the air flow rate depends on the water vapour content inside the room.
The element responsible for automatic adjustments is a hygrometer equipped with a polyamide sensor that measures relative humidity of the air inside the room and directly controls the position of the damper of the air inlet vent.
In this way, it adjusts ventilation efficiency to the level of humidity – it increases efficiency at high humidity and decreases it at low humidity. The device operates automatically and does not require any electric power supply.
Owing to such a mode of operation, it always maintains proper level of humidity inside the building without the need to cool down the room.
These vents are intended for use in rooms equipped with natural or mechanical exhaust ventilation.
