Backdraft Damper - Adjustable Counterbalanced - Triple-V Blade - BD-84

Adjustable counterbalances attached to the blades axles permit field adjustment to regulate start-to-open and full 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.
