Intense Air Immixture
The swirl outlet of the VVT diffuser makes intensive air immixture possible.
Automatic Regulation
The VVT diffuser has automatic regulation and does not require an additional energy supply.
Air Distribution System
It’s possible to connect the VWT swirl diffuser to an air distribution system with a plenum box.
The VVT swirl ceiling diffuser with thermostatic regulation and fixed blades is a well-appointed distribution element for air supply. The front panel is equipped with radially aligned blades of different shapes, which ensure an even distribution of swirl supply air into the working area. On the internal side, the thermostatic regulation of the diffuser ensures supply airflow vertically downwards.
Regulation of the VVT is automatic, and it doesn’t need an additional energy supply. It’s possible to connect the VVT swirl diffuser to an air distribution system via a plenum box with a horizontal or vertical connection using circular flexible or rigid piping. The swirl outlet makes intensive air immixture possible.
The VVT is manufactured with a square front panel made of galvanised steel. The surface is powder painted. Every VVT front panel includes a screw with a decorative white cap for its mounting onto a plenum box as well as a self-adhering seal, which needs to be placed onto the diffuser front panel during the installation. Other sizes are available in this range.

Specification
Swirl diffuser with thermostatic regulation and fixed slats. Designed for the temperature-dependent introduction of supply air. The diffuser surface is supplied with a radially aligned set of straight (A) or curved (B) slats, which ensure an even distribution of the swirled supply air into the room. The thermocouple regulates the temperature between 17°C and 35°C, no additional energy supply is required. Cold air is ejected horizontally, warm air vertically. The swirl diffuser is installed into the ventilation system using a junction box (available separately) with a horizontal or vertical connection. The installation height is max 4 m.DesignThe diffuser is made of galvanized sheet steel. It can also be make these from stainless steel AISI304 or AISI316. The surface is powder-coated in RAL9003 (signal white) as standard; other RAL colors can be applied on request.
