Constant volume control dampers made of fire retardant plastics. The range covers an air flow range between 15 up to 700 m³/h within a pressure range from 50 up to 250 Pa. Air flow can easily be adjusted within the airflow range of each damper.
Application
To obtain constant air volumes in ventilation and air conditioning systems within a pressure range between 50 and 250Pa
For air supply or exhaust duct systems
Maximum working temperature 60°C
Colour
Black
Composition
Valve and piston made out of fire retardant plastics M1
Body in fire retardant plastics M1
Stainless steel calibrated spring
Rubber air-tight sealing
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
Accessories
Screw driver Torx T10 for unscrewing the screw for adjusting the air flow rate of the
regulator.

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
