Product identity
The Dayton 22CV86 is a rectangular balancing damper sized for 12 by 10 inch ductwork. It provides manual single-blade airflow regulation in commercial and residential HVAC installations. The galvanised steel frame and 20-gauge blade suit low-velocity, low-pressure systems. Installers needing automated actuation or higher pressure ratings should choose a different model.
Sustained-load behaviour
The damper is rated for continuous operation at up to 2,000 feet per minute and a maximum pressure differential of 1.0 inch water column. Its manual locking quadrant holds the blade position without drift during extended fan cycles. The 22-gauge frame maintains structural rigidity under these conditions. Systems exceeding the stated velocity or pressure limits require alternative components.
Thermals noise and power
Operating temperatures up to 180 degrees Fahrenheit are supported with no powered actuator to generate heat or noise. The manual mechanism adds zero electrical load to the building management system. Galvanised steel construction resists corrosion in conditioned airstreams. No fan, motor or control circuitry is present to create audible output or consume power.

Questions about this item
Will the manual quadrant on this 22CV86 damper rattle or add noise when air moves at 2,000 FPM?
The locking manual quadrant secures the blade position, so vibration at the rated 2,000 FPM maximum velocity is minimised during all-day operation.
What duct opening must already exist for the 12x10 frame to fit without modification?
The damper requires a 12-inch by 10-inch duct cut-out to match its 11 3/4-inch frame width and 5 3/4-inch frame height.
Can the galvanized steel frame and 20-gauge blade handle the 180 °F limit alongside older ductwork rated for lower temperatures?
Yes, the 180 °F maximum temperature rating exceeds typical low-velocity system limits, so it will not degrade older ducts operating below that threshold.
