PTVI / PRVI

The perforated diffuser type PTVI is suited for supplying cooled and heated air with a large temperature differential with respect to the room temperature. The perforated diffuser type PRVI is suited for return air.
The seperate plenumbox is fitted with a polystyrene filling and can be used in poured concrete. After the concrete forming the polystyrene filling is removed and the diffuser can easily be fitted. The four in-built pattern blades enable a free choice of the discharge direction, also after mounting.
Prior to adjustment refer to the performance data. The high induction effect enables a high number
of air changes. The precise radial pattern minimises ceiling smudging. The very shallow inflow pattern also makes the diffuser type PTVI suited for somewhat lower spaces.
