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 ADLQ ceiling diffusers have fixed blades. Horizontal air discharge is four-way. The supply air to room air temperature difference may range from –10 to +10 K.

To give rooms an aesthetic, uniform look, Type ADLQ diffusers may also be used for extract air.
