Ceiling diffusers direct the air from air conditioning systems into the room. The resulting airflow induces high levels of indoor air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Ceiling diffusers allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall indoor ventilation, creating only low turbulence in the occupied zone.


Ceiling diffusers type DLK-AK have fixed blades. Horizontal air discharge is one-way to four-way. The supply air to room air temperature difference range from -10 to +10 K.

Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

The maximum volume flow rates apply to a sound power level of approx. 50 dB (A).

Exact values for all parameters can be determined with our Easy Product Finder design programme.
