In this video we explain the differences between GDR air devices. G-Grilles, R-Register and D-Diffusers. We also highlight the importance of face velocity to obtain adequate air flow and noise control for each category. We also mention the continuity equation Q = V*A which is the main formula that relates air distribution.
