Dayton Balancing Damper 14 in 13 7/8 in Damper Diameter

Round balancing damper for 14 in ductwork

This round balancing damper fits a 14 in duct and uses a 13 7/8 in blade diameter to regulate airflow in HVAC systems. It is built for installers and facility managers who need manual volume control on circular duct runs. The galvanized steel construction suits commercial and light industrial installations. It operates up to 180 degrees F and 2,000 FPM maximum velocity.

Galvanized steel frame with manual locking quadrant

The frame and blade are both 20 gauge galvanized steel with a 6 3/8 in frame depth that slides into standard round duct. A 3/8 in square manual locking quadrant lets technicians set and lock blade position without tools. Synthetic acetal sleeve bearings provide smooth rotation and resist corrosion in damp environments. The assembly handles a maximum pressure differential of 1.0 in wc.

Rated for 180 degrees F and 2,000 FPM airflow

At the rated 2,000 FPM maximum velocity the damper maintains its seal within the 1.0 in wc pressure differential limit. The acetal bearings and single blade design keep operating noise low during normal air handling. No external power is required because the quadrant is manually operated. The temperature ceiling of 180 degrees F covers typical supply and return air streams.
