VR – Quarter-round displacement diffuser
Discreet nozzle diffuser for corners
VR is a quarter-round low velocity air diffuser suitable for installation in various types of premises where discreet and efficient air distribution is desired. The diffuser can be mounted against a wall or in a corner, making it particularly useful in rooms with limited space or where the room’s design aesthetic needs to be preserved.
With a complementary plinth, the diffuser can be connected from below. For top connection, the height of the diffuser can be adjusted so that the connecting duct is hidden for a clean and integrated installation.
The diffuser features internally mounted REPUS® nozzles that provide even air distribution across the entire front surface. The design ensures short near zones, high comfort, and a completely maintenance-free system without the risk of clogging.
