Mounting

  • For mounting inside round ducts
  • Horizontal as well as vertical mounting applicable
  • For horizontal mounting, the BAS marking has to be at the bottom
  • To be installed in accordance with the correct air flow direction
  • To be installed in the air intake at a minimum distance of three times the diameter of the duct starting from the air intake grilles and at the same distance from places with a high degree of turbulence in the duct, such as branches, bends,….
  • To be installed in the air outtake at a minimum distance of one time the diameter of the duct starting from the extraction grilles and at the same distance from places with a high degree of turbulence in the duct, such as branches, bends,….
  • The volume control damper has to be easily accessible for maintenance

Pressure loss

Symbols and specifications

  • Q [m³/h] = Air flow rate in m³/h
  • Q KVR-R = Set flow rate in the volume control damper
  • Ps [Pa] = Static pressure loss in the volume control damper in Pa

  • The graphs characterize the variations in the air flow in air supply and extraction with respect to the pressure differential in Pascal at a pressure set between 50 and 250Pa. The flow rates shown are average values ​​and may vary as follows:
      • For Ø80: +/- 3 m³/h
      • For Ø100 and Ø125: +/- 3 m³/h for air volume <= 50 m³/h, +/-5% for air volume >50 m³/h
      • For Ø150, Ø160, Ø200 and Ø250: +/- 5%

Construction

  • 1. Collar with sealing
  • 2. Intermediate piece according to the air flow rate
  • 3. Casing
  • 4. Regulating element
  • 5. Air flow rate regulating module
  • 6. Blocking screw for regulating module
