Circular diffusers are terminal HVAC elements for air distribution. The outlet surfaces of the diffusers are made of fixed profile blades (the circular design guarantees an even airflow in all directions when supplying air) or of adjustable profile blades (by changing the angle of the air outlet, intensive mixing of the supplied air is ensured). We recommend connecting the circular diffusers to the ductwork via a plenum box, thanks to which you will achieve an even air flow, including the possibility of control. Some types of circular diffusers can be installed directly in the ventilation ducts. Upon request, they can be produced in any colour according to RAL and manufacturer's price list.

The square diffusers are terminal HVAC elements for air distribution. The diffusers have front outlet surfaces made of fixed or adjustable profile blades, which are arranged horizontally. The blades are supplied in various configurations - basic (square). The blades are also available as adjustable for some types of the square diffusers. The swirl square diffusers can be used in office buildings, shopping malls and other spaces. We recommend to connect the square diffusers to the ductwork via a plenum box, thanks to which you will achieve an even air flow, including the possibility of control. Some types of the square diffusers can be installed directly in the ventilation ducts. Upon request, they can be produced in any colour according to RAL and manufacturer's price list.

The VVKN swirl diffusers are used as end ventilation elements for air supply and exhaust. The front plate of the diffusers consists of fixed blades, which ensure an even air supply. The circular or square front plate of the diffuser is made of galvanized steel sheet with white powder coating RAL9003. On request, the front plate can be supplied in stainless steel (A304 or A316) or in another RAL colour. Installation can be done by connecting the diffuser to the ducts using a circular or square plenum box.

The VVKR circular / square swirl diffusers with adjustable blades and circular / square front plate are end ventilation elements intended for supply and extraction of heat-treated air. The front plates are made of adjustable blades, which ensure an even air supply to ventilated spaces. The circular / square front plates are made of galvanized sheet metal with RAL 9003 or RAL9010 finish. The blades on the front panel are made of black or white plastic. For extraction diffusers, it is possible to supply a front plate without blades. On request, they can be supplied in any RAL design or made of aluminium or stainless steel sheet AISI304 or AISI316L

The VVT swirl diffusers with fixed blades equipped with thermostatic control are used as air terminal elements for air supply. The thermostatic control allows the flow pattern to be automatically changed based on the change in supply air temperature (20 - 30°C). In cooling mode the air is supplied horizontally and in heating mode it is supplied vertically. Recommended installation height 2.6 to 4 m, for air flow volumes of 100 to 800 m³/hr. 

The front plate of the VVT swirl diffusers is made of a thermostatic cartridge and fixed blades that ensure uniform air supply and is made of galvanized steel sheet with white powder coating RAL9003. The profiled blades on the faceplate form different concentric patterns - A or B shape. 

On request, the faceplate can be supplied in aluminium or stainless steel (A304 or A316L) or in any other RAL colour. On request, it is also possible to supply a faceplate in 600 or 625 mm with a 300/400/500 mm pattern. Installation can be done by connecting to the duct route using a plenum box. 

CAP-RD
The CAP-RD linear multi-nozzle diffusers are designed to be installed directly on circular ducts for both supply and exhaust air. The CAP-RD duct diffusers are suitable for industrial or public areas with exposed ductwork with installation heights up to 6 metres. The CAP-RD nozzle diffusers are made of RAL 9003 galvanised steel and the individually adjustable nozzles are made of RAL 9003 polymer and can be directed to any angle - other colours on request.

CAP-SD
The CAP-SD linear multi-nozzle diffusers are designed to be installed directly on four-sided ducts for both supply and exhaust air. The CAP-SD duct diffusers are suitable for industrial or public areas with exposed ductwork with installation heights up to 6 metres. The CAP-SD nozzle diffusers are made of RAL 9003 galvanised steel and the individually adjustable nozzles are made of RAL 9003 polymer and can be directed to any angle - other colours on request.
