New Design DF Swirl Diffusers, DF2 Series The Wildeboer DF Swirl Diffuser, DF2 series, is a re-engineered design of the DF Swirl Diffuser. In contrast to the previous design, these diffusers have a smooth gloss powder coat paint finish in RAL 9010 with 80% to 90% gloss level. The plenum boxes of the new DF2 series have been optimized for low installation heights and are likewise available with powder coat paint finish. Setting volume flow rate is possible without dismounting of the swirl diffuser. Please take note of the
modified installation dimensions for the plenum boxes, in particular with regard
to the new ceiling flush mounting design. You can find further information in catalogue 2.12 . Orders for DF Swirl Diffusers will be processed in the new DF2 design from week 10 2008.
