The LBQ is a linear Displacement diffuser that provides low-turbulence supply and extract air and is installed in floors and raised floors.


Our products adapt individually to your project requirements. This gives you maximum flexibility for every project. The selection of height, width and cover is made in close coordination with you.
The following grille or perforated plate versions are available:
The LBQ is installed flush in the raised floor – the standard construction method for office floors. This means that available space is used optimally.


Individual units of the LBQ floor displacement diffuser are coupled together and, thanks to the continuous cover and the frame edge, are perceived as a continuous strip.
You have the requirement - you have the choice. The LBQ enables the supply air connection by means of round or oval duct spigots.
