Adjustment- and silencer unit ROL-S is the best and safest option for applications where high standards are set for adjustability, noise level and appearance. ROL-S consists of the opened adjustment unit functioning also as a cleaning hatch and of a high quality silencer unit after the adjustment unit. The silencer absorbs the sounds coming from the adjustment and also effectively inhibits the migration of the air sounds coming from the duct work going into the room.
