Air Terminal Circular duct grille

Circular duct grille is a rectangular ventilation grille with vertically adjustable bars designed for direct installation in circular ducts. It is suitable for both supply and exhaust air applications and can be equipped with horizontal directional bars, straight or slanted sliding dampers, or blade dampers. The grille is engineered so that its flanges always fit tightly to the duct, regardless of duct diameter. Constructed from hot-galvanized steel sheet and assembled without welding, the circular duct grille requires no additional surface treatment, ensuring that its exterior fnish matches the duct surface. It can be used for both supply and exhaust air, installed directly into circular ducts, and fitted with a variety of accessories.
