Bard part 521-221 is an OEM blower partition assembly used inside select Bard wall mounted HVAC units to separate the blower section from adjacent compartments so air is routed through the intended path across the coil and into the supply. A properly fitted partition helps prevent air bypass and recirculation inside the cabinet, which supports stable airflow, quieter operation, and correct temperature control, especially after service work where panels may be bent or missing. Because partition designs vary by chassis and model series, confirm 521-221 against your unit model and serial number or the correct Bard parts list before ordering to ensure proper fit and sealing in the blower compartment.
