Abstract
A damper system includes a damper housing configured to flow air, a damper blade disposed in the damper housing and having an orifice, the damper blade being rotatable in the damper housing between a closed position and an open position. The orifice is configured to allow air to flow through the damper blade while the damper blade is in the closed position. An auto-balancing damper is disposed in the damper housing apart from the damper blade, and the auto-balancing damper is configured to regulate a flow of the air through the damper housing.
