Practical gravity ventilation grille with a self-acting louver for façade installation. Opens automatically by air pressure when the fan is running and closes after switching off, thereby preventing heat loss and the ingress of cold or dirt. Durable plastic and an elegant white color for discreet integration into the exterior.
This gravity ventilation grille is an ideal solution for exhausting air from kitchens, bathrooms, or utility rooms. The self-acting louver opens only when air is flowing and automatically closes when it stops, reducing heat loss and improving the home’s energy efficiency.
Thanks to its durable plastic construction and white finish, it is easy to maintain and visually blends with most façades. The 150 × 150 mm size with a 100 mm duct connection enables versatile use in common household ventilation systems.
