VVT
Swirl Ceiling Diffuser with Thermostatic Regulation and Fixed Blades
Description
The VVT swirl ceiling diffuser with thermostatic regulation
and xed blades is a well-appointed distribution element
for air supply. The front panel is equipped with radially
alligned blades of different shapes, which ensure an even
distribution of swirl supply air into the working vents.
The thermal regulation element on the internal side of
the diffuser supply air discharge pattern based on its
temperature. The cold air ows into the area horizontally,
the heated air ows vertically downwards. The range of
temperatures between these extremal positions is
20 °C to 30 °C. The regulation is automatic, without a
need for additional energy supply. It is possible to use
the diffuser in areas with clearance height up to 4 m. The
VVT swirl diffuser connection to an air distribution system
is possible via a plenum box with a horizontal or vertical
connection using circular exible or rigid piping. VVT is
used for air supply.
Important!
The thermal change between extremal positions for
vertical and horizontal air ow pattern requires app. 5 to
10 minutes.

diffusers can be found from page 3.
