Bard part 139-157 is an OEM damper blade used in Bard wall mounted HVAC equipment to help regulate intake airflow as the damper assembly opens and closes. If your unit is sticking, leaking outside air, or failing to modulate ventilation properly, replacing the damper blade can restore smooth damper operation and more consistent airflow control. This is a fit critical internal air control component, so confirm your exact Bard model and the intake damper assembly breakdown before ordering to ensure the correct blade is selected for your specific unit configuration.
