The BD-1300 balancing damper is designed for manual or automated balancing of airflow in heating, ventilating, and air conditioning systems. The BD-1300 is not a leakage-rated damper. It is available in 1-inch increments.
The rigid frames are constructed of formed 13-gauge galvanized sheet steel, mechanically joined with linkage concealed in the side channel to eliminate noise and friction. Self-lubricating acetal or bronze bearings are available.
Johnson Controls® BD-1300 dampers have no components that require routine scheduled maintenance.
Refer to the BD-1300 Balancing Dampers Product Bulletin (LIT-2681015) for important product information.
