Bard 538-179 - Fresh Air Damper (FAD) Assembly

Bard part 538-179 is an OEM FAD (fresh air damper) assembly used on select Bard wall-mount HVAC units to introduce and control outdoor ventilation air into the cabinet. Replacing the complete assembly is a practical fix when the damper hardware is bent, binding, or no longer seals correctly, since it restores proper air control and helps prevent unwanted outside air from sneaking in when the damper should be closed. Because Bard offers multiple ventilation and cabinet configurations across model families and sizes, confirm compatibility by matching the part number to your unit model and serial number or the unit parts list before ordering.
