Gravity Ventilation Grille VM, 200 x 200mm G/150mm, White 0237

The HACO VM 200x200mm ventilation grille finishes ventilation ducting on building facades. Its main purpose is to provide ventilation while preventing air backflow. Thanks to the gravity flaps, the louvres only open when air flows outwards, preventing cold air from entering the ducting. Made from UV-resistant ASA plastic, the grille is suitable for both indoor and outdoor installation.

Functional design and easy installation

Air pressure from the inside opens the louvres automatically. As soon as the airflow stops, the louvres close under their own weight to seal the opening, preventing cold air backdraughts. The grille is made from UV-resistant ASA plastic. The package includes screws, wall plugs and a sealing strip.
