In addition to the existing range of TROX swirl diffusers, the Type SDW swirl diffuser with manual adjustment for heights from 2.6-4.0m has been developed. This enables the direction of discharge to be altered on site to cater for changes in room layout or partitions.
Due to the rotary swirling motion of the air discharge, induction of room air occurs very quickly, resulting in a rapid decay of supply air velocity and temperature differential. Air change rates of 30 per hour can be achieved with supply air temperature differentials of +10K to –10K.
The diffuser can be supplied with white or black air control blades depending on architectural requirements and is available with multiple border profiles to suit most ceiling systems.
Air is supplied via top or side entry plenum boxes.The Type SDW can be used for either supply or extract air application. For supply air, special control elements are required. These are not necessary for use in the extract air mode.
