Exhaust air systems

GAL gravity roof ventilators are suitable for all industrial applications. They are constructed with shaft widths ranging from 500 mm to 10,000 mm and a coefficient of discharge (Cv0) that no other ventilator in the world can match of up to 0.78.

GAL gravity roof ventilators are designed for production buildings with medium and high specific heat loads or high air exchange rates. They are distinguished by their flat, aerodynamic silhouette. The gravity roof ventilators are manufactured to the required length and installed on the building, and the ventilation elements are adapted to the roof structure and shape.
