In a conventional air distribution system, to balance the supply of the air among the distribution system, a device called Damper is installed, by using a simple nut and bolt, near the exit of the air from the air distribution system (duct system). To regulate the air supply, the damper is rotated in clockwise or anti clockwise. As the damper is fastened by a nut only, so sometimes it become loose during balancing and hence precise balancing of the air system cannot be achieved. Most of the times the nut is unapproachable, after the completion of construction, so it is very difficult to precisely balance the air system.

Short comings of Conventional Volume Damper

  • The Damper orientation cannot be fixed at one particular position dueto lack of accessibility to wing nut.
  • As designed CFM cannot be allocated to the rooms so Hot and Cold spots are produced in the home.
  • To overcome these Hot and Cold spots, the home owner ends up installing supplemental heating and/or cooling devices, which further dents his pocket.
  • The vibrations in the duct work some times causes the Volume Damper to rattle.
