• Adapter Partition Assembly

Bard 521-345 is an OEM adapter partition assembly used inside select Bard wall mounted packaged HVAC units to maintain the correct separation between internal sections so airflow follows the designed path and components stay properly isolated. This partition helps preserve unit performance by supporting stable air movement through the cabinet and reducing unwanted air bypass that can lead to comfort issues or nuisance service problems. As a genuine Bard replacement part, 521-345 is intended to match original fit and mounting points for a straightforward service replacement when the existing partition is damaged, missing, or distorted, but always confirm compatibility by model and serial number before ordering.
