Mounting
The VVKN swirl diffuser is most commonly installed
onto a ventilation duct as illustrated on Fig. 8.
The mounting consists of installing the plenum box
to the ceiling using draw-bars and mounting the diffuser
face onto the plenum box using a centric screw which is
included in the delivery.

Fig. 8 depicts various methods of installing the VVKR
onto the ceiling. When mounted into a suspended
grid ceiling the supply air swirl is expected to be
partially reduced. It is therefore needed to respect the
minimum distance of the diffuser - at least 150 mm
from the grid ceiing.
