Swirl Diffusers | 5 / 5
Mounting
The VVT swirl diffuser is most commonly installed onto
a ventilation duct as illustrated on Fig. 7. The mounting
consists of installing the plenum box to the ceiling using
draw-bars and mounting the diffuser front panel onto
the plenum box by a centric screw which is included in
the delivery.

Fig. 7 depicts various methods of installing the VVT 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 ceiling.
