PTVM, PRVM

3D Presentation Zoom
The ceiling, perforated PTVM intake diffusers are used for supplying cold or warm air in the systems where the temperature difference between the room and air outside is large.
 

APPLICATION: PTVM (air intake)

The ceiling, perforated PTVM intake diffusers are used for supplying cold or warm air in the systems where the temperature difference between the room and air outside is large. The intake diffuser is designed for installation in modular suspended ceiling with 600 mm panels.

On request, it may be installed along with a plenum box. High efficiency of the diffuser allows for obtaining a large air change rate. A precise, radial pattern minimizes formation of streaks on the ceiling. Due to a horizontal stream of supplied air, the PTVM diffusers are suitable for relatively low rooms.

APPLICATION: PRVM [ exhaust]

The ceiling, perforated PRVM diffusers are used for air exhaust. Its appearance is identical as that of the PTVM intake diffuser. The diffuser is designed for installation in modular suspended ceilings. On request, it may be installed along with a plenum box.
