Volumetric Flow Controller VRAPPs

Fields of application

For the control of variable and constant volumetric air flow in ventilation and air-conditioning installations with air loaded with aggressive media.


The static volumetric flow controller regulates the air volume throughput either constantly or variably. Positive control toVmin, Vmax or “Closed” is possible. The measuring crosses, comprising 12 measuring points each, distributed in accordance with the median line method, enable a very accurate measurement of the air volume throughput. The error of measurement is ± 5% of the rated volume.

Volumetric flow range
