AL-dB has been developed to satisfy the ever increasing demands for noise reduction and at the same time achieving good indoor climate. The front section of the vent is shaped to provide low air speed and a good mixture with the ambient room air. The vent is available in two lengths, 456mm and 806mm. The shorter vent is also available with a special storm shield (regulates air supply during heavy winds). An external grille is available as accessory (made of plastic).
