Quiet-Vent Linear Duct Mounted Grille

Spiral duct mounted grilles are designed to fit directly to circular spiral duct without needing special take-off. When using to supply air, the angled hit and miss sliding damper acts as an air deflector as well as a damper.

Spiral duct mounted grilles are suitable for supply and extract airflows from spiral round air ducts. They are suitable for applications such as offices, shopping centres and any location that is using exposed ductwork.
