VRFactive
The VRFactive flow rate controller has been designed to control initial pressure independent constant or variable flow rate.
The VRFactive electronically controls flow rate based on constant or variable set values, independent of changes in pressure (within specified range). The damper has a very short installation case depth, making it ideal when space is at a premium. Precision control at low flow rates (1 m/s).
- Control range 1-10 m/s with damper pressure losses of 20 to 1000 Pa
- Admissible differential pressures based on ambient pressure +1000 Pa and -750 Pa, according to Class C, Pressure Class 2 (DIN EN 1507)
- Casing leakage acc. to Class C, damper leakage acc. to Class 2 (DIN EN 1751). Grading of duct widths and heights acc. to DIN EN 1505
- Flow Rate Controller VRF-W consisting of:
- Damper blade of galvanized sheet steel with peripheral EPDM seal
- Maintenance-free damper bearing of plastic
