The beautifully designed round duct blade 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.

• For visible installation in supply and return air systems.
• Round duct with integrated blades arranged in a line, which can also be adjusted by hand on-site, with hit-and-miss damper.
• The uniform admission allows the DBBRR to be installed at any point along the duct system.
• Suitable for connection to DIN ducts
