Model BD-84 adjustable counterbalanced backdraft damper triple-V blade

Application

BD-84 backdraft dampers employ counterbalanced gravity operated triple-V blades and a rugged channel frame to restrict reverse airflow and to permit the forward flow of air in the intended direction. Adjustable counterbalances attached to the blades axles permit field adjustment to regulate start-to-open and full open blade operation. The BD-84 damper is intended to be mounted vertically in either exhaust or intake installations for medium to high velocity and pressure applications.
