Bard 121-504 - Return economizer partition

Bard part number 121-504 is an OEM return economizer partition used in select Bard wall mount packaged air conditioner cabinets to separate and direct airflow between the return air path and the economizer section. A properly fitted partition helps prevent air bypass and mixing that can reduce ventilation control, create uneven temperature across the coil, or lead to nuisance issues during economizer operation. This is an internal sheet metal cabinet component intended to restore original air routing and cabinet integrity when the existing partition is damaged, corroded, or missing; confirm fit by matching your unit model and serial number to the correct Bard parts manual before ordering.
