DescriptionThe characteristic feature of the ceiling air diffuser type DBB forsupply and return air is its high flexibility. The integrated bladesallow many air distribution patterns even later on. It is often thecase that unforeseen installations of components into the ceil-ing make it necessary to change the air throw pattern on site.Some of the many available air throw options are shown below.
Attention:As standard, the ceiling air diffuser type DBB-...-A-... in returnair model is delivered with blades. Only for large air volumes willthe DBB return air model be delivered without blades on requestby the customer. This model is only available with hit-and-missdamper painted in black!
