• Adapter Partition Assembly

Bard part number S521-436 is an OEM Adapter Partition Assembly used inside select Bard wall-mount HVAC units to separate sections of the cabinet and guide air where it needs to go, which helps prevent bypass air and supports proper airflow across the coil and fan assembly. If your original partition is damaged, missing, or has been removed during service, replacing it with the correct factory partition helps restore the unit’s designed internal air path and reduces the chance of nuisance issues like poor capacity or uneven airflow. Because partition layouts vary by model and vintage, confirm S521-436 against your Bard unit model and serial number or the correct parts list before ordering.
