The plenum boxes used for VRV and VCV equipment are designed to distribute the air before it is diffused through the end elements. Depending on the intended use, the plenum boxes are insulated (on the inside or outside) with armaflex or uninsulated.
The plenum boxes are equipped with one or more nozzles suitable for connection of flexible circular ducts, spiro ducts or rectangular ducts. If needed, with the purpose of controlling the air distribution, they can be equipped with dampers.
