Round duct blade diffuser DBBRR

Fields of application

For the visible installation of ventilation and air-conditioning installations in trade fair halls, foyers, sports halls, factory halls and multi-purpose halls, shopping centres, etc. Suitable for supply and return air.


The beautifully designed round pipe diffuser enables the implementation of modern architectural designs and impresses with its outstanding technical characteristics. The air deflection blades, adjustable manually, run centrally on bearings, thus maintaining the free cross-section at all blade positions. In this way, neither the pressure loss nor the volume level change when the blades are adjusted. Both horizontal (for cooling) and vertical (for heating) throw patterns are possible.

Volumetric flow range
