Product: Automatic Balancing Dampers
Description: Maintaining a constant airflow by adjusting to changes in system pressure, this product is designed for use in both supply and exhaust applications. The damper blade automatically adjusts position to account for changing pressures in the ductwork. Over 20 cfm set points allow for easy field adjustment without the use of any additional tools. It can be installed directly into round ductwork without the need for any fasteners or use of any adhesive. Constructed of antimicrobial plastic to inhibit microbial growth, model ABD is UL2043 classified for flame spread and smoke development. It is also available with a flanged-grille mounting box (model ABD-GM) or with a square to round transition (model ABD-T).
