Ceiling diffusers DLQ Functional description Ceiling diffusers direct the air from air conditioning ​ systems into the room. The resulting airflow ​ induces high levels of room 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 room ventilation, creating ​ only very little turbulence in the occupied zone. Type DLQ ceiling diffusers have fixed blades. ​ Horizontal air discharge is four-way....

Ceiling diffusers Technical data Nominal sizes Minimum volume flow rate Maximum volume flow rate, with LWA ≅ 50 dB(A) Supply air to room air temperature difference

Ceiling diffusers DLQ 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.
