Description
A ventilation grille with a gravity louver is a highly functional solution. The louver opens under the influence of airflow. When the fan is turned off, the grille closes. A ventilation grille with a gravity louver prevents backdraft in the ventilation system, reducing heat loss and protecting the interior of the ventilation system from weather conditions. Available in a variety of colors, DOSPEL's 50 years of manufacturing experience guarantee the highest quality.
