• ERV Vent Opt Door Assy-Gray

Bard S553-529-4 is an OEM ERV vent option door assembly used on select Bard wall mounted packaged HVAC units equipped for energy recovery ventilation. This door is the correct cabinet access cover for the ERV vent opening and helps maintain proper cabinet sealing and airflow routing so the ERV option can operate as designed without unwanted air leakage. Because Bard uses different vent door configurations across model families and ventilation options, confirm the unit model and serial and match the full part number before ordering to ensure proper fit and alignment.
