Combined Supply and Return Air Diffuser Model KWB Model KWB-KL KWB-D-1/2 KWB-DSX-1/-2/-3 KWB-S Description Application Ceiling diffusers often cannot be installed in rooms due to low ceilings. In this case, rooms are ventilated with combined supply and return air diffusers installed in the wall. Supply air is delivered into the room at an angle from one side. The developing forced air circulation enables optimum room flow and fresh supply air is distributed uniformly over the entire room. In all KWB models, a stable air jet is produced, which is stable even at a temperature difference AT0 = -10...

Combined Supply and Return Air Diffuser Model KWB Technical dataPressure loss and noise level KWB-D-1 600 Construction subject to change.

Attention: For the KWB-DSX-3 slotted module, make sure that the connection spigot velocity, at a connection spigot length of 98 mm, does not exceed 3 m/sec. If the 3 m/sec are exceeded due to a higher air volume, two connection pieces each (0 98mm) must be planned for the supply and return air units, in order to avoid noise problems!
