IVS Dampers
Dampers for these systems are used to balance air flow and control air volume. They are industrial duty and have ball bearings on each shaft. Blades can be single thickness or airfoil to minimize pressure drop. Materials of manufacture include carbon steel (painted), stainless steel, and aluminum. Operators are selected based upon required torque and are manual quadrant, manual gearbox, pneumatic or electric. Damper linkage is usually outside the airstream to permit service access and to ensure long trouble free operation. Dampers can also be supplied for fire suppression media containment. This prevents the fan from blowing the chosen fire protection media out of the system.
