Round Duct Grille DBBR H Description Supply and return air grille especially for duct installation, with front side horizontal pivoting air deflection blades. Open cross-section, resistance and noise remain constant in all blade positions. Please note that cutting the folded spiral ducts may produce tensions that can affect the grille and which the grille cannot withstand. This is why the grille length should be limited to max. 815 mm when being installed in spiral ducts. The installation of DBBR into spiral ducts must take place free of stress. Avoid using unround or deformed spiral ducts, in...

The three height measurements enable optimum adaptation of the round duct grille type DBBR to sheet steel or spiral ducts. The selection of the grille height depends on the duct measures shown in the table. When ordering, it is absolutely mandatory to specify the duct diameter for which the grille is used. For the dimension 1215 mm in a single-part design, the minimum duct diameter is 355 mm. For a two-part design of this dimension, the above table values apply. For additional technical data, please refer to the air-related documents of the round duct blade diffuser type DBBRR. The installation...
