KVR-R • Adjustable constant air volume dampers

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.

• 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

• Black

• Valve and piston made out of fire retardant plastics M1
• Body in fire retardant plastics M1
• Stainless steel calibrated spring
• Rubber air-tight sealing

• 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

• Screw driver Torx T10 for unscrewing the screw for adjusting the air flow rate of the regulator.
