GS Gravity Shutter

The gravity shutter has been designed for ventilation duct outlets, especially those discharging air from the building to the outside. It is intended for wall or façade installation. Forced airflow in the duct, for example generated by a fan, lifts the gravity blades and allows exhaust air to be discharged. When there is no airflow, the grille design protects the building against backdraft. In winter, the shutter helps prevent heat loss through an open ventilation opening.
