Bard 139-291 - Damper Blade

Bard part number 139-291 is an OEM damper blade used in Bard wall-mount air conditioner ventilation and economizer damper assemblies to regulate outdoor air intake and support proper free-cooling operation when equipped. A worn, bent, or sticking blade can cause poor ventilation control, air leakage, or inconsistent damper movement, so replacing it with the correct Bard factory part helps restore smooth blade travel and proper airflow control. Verify fit by matching your unit model and damper assembly breakdown, since damper blade styles and linkage points can vary by series and vent option.
