Displacement air diffuser QA

Fields of application

Supply air installations with displacement ventilation in offices, industrial workshops and laboratories, with localised high heating loads or polluted room air.


The supply air is blown into the room in the floor area over a large area via the displacement diffusers, at low air outlet speeds. The supply air spreads out across the floor and is directed upward by the convection currents of the heat sources.
Due to the low-induction flow rate, the pollutant-containing air is displaced to the return air apertures, which should be mounted above the heat sources or, in the case of heavy pollutant particles, at the floor.

Volumetric flow range

200 - 15000 m³/h
