Volume flow regulator - circularVRU

VRU is a circular volume flow regulator for VAV regulation in duct systems and consists of a measuring unit and a damper. VRU is used for volume flow regulation in circular ducts controlled from e.g. a room controller or BMS. VRU is as standard supplied with MF actuator without communication, but can on request be delivered for Belimo MP, LON, KNX or ModBus communication. Further documentation on the actuator can be requested from Lindab.

VRU is equipped with LindabSafe for connection to the duct and is prepared for insulation up to 50 mm.

VRU can be installed in any position without adjustment required. To avoid contamination of the measuring cross, VRU should only be used for clean air.
