Function and effect

The grille TN is used in pipe systems and servers as a single diffuser. The aerodynamic form of the blades and their installation with blind frame enable a vibration-free and quiet operation. The adjustability of the blade makes different jet forms (from concentric to diffuse) and therefore different throw ranges possible.
