Dayton 22CV84 Rectangular Balancing Damper 8x6 hvac control

SKU CH-FK7N-F6KR2

Manual rectangular balancing damper with galvanised steel frame and locking quadrant for 8×6 ductwork

  • Manual airflow control with locking quadrant
  • Galvanized steel frame resists corrosion
  • Rated for 2,000 FPM maximum velocity
  • Withstands temperatures up to 180°F
  • Handles 1.0 in wc pressure differential

Rectangular Balancing Damper for HVAC Systems

The Dayton 22CV84 is a manually operated single-blade damper designed for rectangular ductwork in low-velocity and low-differential-pressure HVAC systems. It provides airflow balancing for commercial or residential installations where precise manual control is required.

Frame Depth Matches 1 7/8 Inch Duct Constraint

The damper frame depth measures 1 7/8 inches, making it the critical specification for fitment within shallow duct cavities or tight mechanical spaces. Installers must verify this exact depth against the available clearance before ordering.

Galvanized Steel Construction Withstands 180

Built from 22-gauge galvanized steel frame and 20-gauge blade, the damper operates continuously at temperatures up to 180 degrees F and velocities up to 2,000 FPM. The locking manual quadrant secures blade position under sustained pressure differentials up to 1.0 in wc without drift.

Questions about this item

How does the 2,000 FPM maximum velocity affect airflow in a real duct?

The damper is rated for velocities up to 2,000 FPM, so it will control airflow without excessive noise or pressure drop in typical low-velocity residential or light-commercial systems.

What does the 1.0 in wc pressure differential limit mean for system design?

The 1.0 in wc maximum pressure differential means the damper should only be used in low-pressure duct sections where the static pressure difference across the blade stays at or below that value.

What are the exact frame dimensions for mounting this 8x6 damper?

The frame measures 7 3/4 inches wide by 5 3/4 inches high by 1 7/8 inches deep, so the rough opening must match those outer dimensions for a proper fit.
