Rectangular Balancing Damper for Low-Velocity
The Dayton 22CV85 is a manual single-blade damper designed for rectangular ductwork in low-velocity and low differential pressure HVAC systems. It suits installers and facility managers who need to balance airflow in commercial or residential sheet-metal ducts.
Locking Manual Quadrant Included
The damper ships with a locking manual quadrant that secures the blade position once the required airflow balance is achieved. This accessory prevents unintended movement from vibration or pressure changes, reducing the need for repeat adjustments after commissioning.
Handles 2,000 FPM at 180 Degrees F
Galvanised steel construction with a 20-gauge blade and 22-gauge frame withstands velocities up to 2,000 FPM and temperatures up to 180 Degrees F. The assembly is rated for a maximum pressure differential of 1.0 in wc, so it is not suited for high-pressure or high-temperature industrial duct networks.

Questions about this item
Will the galvanized steel frame or 20-gauge blade need replacement if the duct sees 2,000 FPM airflow daily?
The damper is rated for a maximum velocity of 2,000 FPM and a maximum temperature of 180°F, so components should not require replacement if operated within those limits.
At what point does the 1.0 in wc pressure differential limit become the first constraint during sustained operation?
The pressure differential limit of 1.0 in wc is the first constraint; exceeding it can prevent the single blade from modulating correctly even if velocity and temperature remain within spec.
How much noise or heat does the manual quadrant add when the damper runs all day in a low-velocity system?
The manual locking quadrant has no motor, so it adds no electrical heat or fan noise; only airflow-generated sound and conducted heat up to the 180°F rating are present.
