The Bard 139-116 damper blade is an OEM airflow-control component used in Bard wall-mount ventilation or free-cooling damper assemblies to open and close the intake path as the unit transitions between ventilation modes. A damaged, bent, or leaking blade can cause poor outside-air control, nuisance temperature swings, and reduced economizer performance, so replacing it with the correct Bard factory part helps restore proper damper movement and sealing against the blade seals. Because damper assemblies vary by series and capacity, confirm fit by matching your unit model and serial number to the appropriate Bard parts manual before ordering the Bard 139-116.
