Spiral duct grille dampers

SGD

Spiral duct grille dampers are manufactured from galvanized steel sheet, ensuring strength and durability. They are installed directly into the circular duct, requiring no frames or other mounting systems. This type of grille is especially used in large spaces where the circular duct is visible, contributing to both the functionality and the aesthetic integration of the system.
