DV
The DV adjustable diffuser is designed
to supply air into industrial premises,
stores, warehouses and sports halls
with medium-height ceilings.

Design
The DV air diffusers are made of alumi-
nium with steel blades that are powder
coated in standard Roccheggiani white.
There are 7 available sizes. They are
connected to the air duct system with
standard diameter, round connections
with rubber seals or using a plenum.

Operation
The major elements of the diffuser are the outer body and the
blades with adjustable synchronized movement. By varying
the angle of the blades (0-90°) you can change the depth of
the throw. The variation of the angle of inclination of the bla-
des allows you to control the residual throw speed optimizing
the application during the summer and winter seasons. The
diffuser is equipped with a equalizer grid made of perforated
sheet. Upon request, the diffuser can be provided with a ple-
num with lateral attachment, and a regulation damper.

Adjustment
The DV diffuser can be adjusted manually or via a servo-motor
placed outside the diffuser housing. You must specify whether
you require manual or servo-motor adjustment at the time of
ordering. Any subsequent modifications can only be done by
the manufacturer.

Fitting
The DV diffusers must be hung. The smaller sizes (up to 315)
can be fixed to the air duct with self-tapping screws or with
pop rivets, if the duct is strong enough and placed securely.
For sizes of 400 and over, we suggest you use 3 fixing points
prepared for M8 bolts.
