A modern hygroregulated vent designed for installation in PVC, wooden and aluminium windows. The vent is regulated by a polyamide tape, which reacts to the humidity level in the room. Depending on the level of humidity, the vent automatically opens or closes itself providing the required amount of air. More over, it has a switch that allows the vent to be manually closed at any time convenient for the user. In addition to gravitational ventilation, SM HY is also ideal for mechanical ventilation systems based on humidity sensors in the fan and the exhaust grille.

• An energy-efficient solution for residential, commercial and public buildings (e.g. schools, hospitals).
• Use in all ventilation systems based on passive supply units
• Hygroregulation – air exchange always adapted to needs
• Humidity sensor in the form of a polyamide strip – no power required
• Three operating modes: automatic, open and closed
• Monobloc removable casing for easy painting and maintenance
• Horizontal orientation of the supply air
• Option of using a flat mesh instead of a hood (installation with external blind)
