V21/V22
Volumetric Flow Controller rectangular

Application in ventilation systems for supply air and return air volumetric flow control and in industrial ventilation systems of 150 m3/h up to 30'000 m3/h and 1.5 m/s to 12 m/s. Types: V21 single walled, V22 double walled.


An integrated precision volumetric flow measuring station generates an increased differential pressure signal. The opposed blade damper ensures air-tight closure.

Characteristic features of controllers:

  • Shorter installation length
  • Lower inherent resistance
  • High precision measurement by averaging multipoint measuring device
  • Opposed air-tight blade damper with very good control characteristic
