• ERV Vent Opt Door Assy-White

Bard part S553-540-1 is an OEM ERV vent option door assembly in white used on select Bard wall mounted packaged units equipped for energy recovery ventilation. This door helps close and seal the ERV vent opening when the ventilation option is installed, supporting proper airflow control and helping the unit maintain intended performance by reducing unwanted air leakage at the cabinet interface. Replacing a bent, rusted, or damaged vent door with the correct Bard factory part restores proper fit and alignment at the ERV access area and helps keep your ventilation setup operating the way Bard designed it.
