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 ADLR ceiling diffusers have fixed blades. Horizontal air discharge is radial. The supply air to room air temperature difference may range from –10 to +10 K.

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

Installation in continuous ceilings 00104903_0.


Installation and commissioning

  • Preferably for rooms with a clear height up to 4.0 m
  • Flush ceiling installation
  • Horizontal or vertical duct connection
  • If necessary, carry out volume flow rate balancing with the damper blade


These are only schematic diagrams to illustrate installation details.

Volume flow rate balancing

When several diffusers are connected to just one volume flow controller, it may be necessary to balance the volume flow rates.

  • Ceiling diffusers with universal plenum box and damper blade (variant -M): The diffuser face can be removed to access the damper blade; the damper blade can then be set to any position between 0 and 90°
  • Ceiling diffusers with universal plenum box, damper blade and pressure tap (variant -MN): The diffuser face need not be removed since the damper blade can be set with two cords (white and green).

Volume flow rate measurement

Ceiling diffusers with universal plenum box, damper blade and pressure tap (variant -MN) allow for volume flow rate balancing even with the diffuser face in place.

  • Connect the measuring tube to the digital manometer
  • Read the effective pressure
  • Read the volume flow rate off the characteristic or calculate it
  • If necessary, adjust the damper blade position with the cords


A characteristic is included with each AK-Uni plenum box.
