VRDactive
Minimum initial pressure at air speed 5 m/s: 23 Pa to 37 Pa, depending on size.
Round twin flow rate controller for constant or variable flow rate controlling in high or low pressure installations, with two parallel control dampers. Thus, only one controller required for supply and return air, initial pressure independent.
- Differential pressure range up to 800 Pa
- Air speed 1 - 10 m/s
- Plug-in installation system to fit lock-seam spiral wound ducts according to DIN 24145
- All components are factory-wired and hose-connected
- Damper position display and angle scale on the outside of the casing
