S553-558 OBSOLETE
- ERV Vent Opt Door Assy - Alum - SVC
Bard part S553-558 is an OEM vent option door assembly designed for Bard wall mounted packaged units equipped with an ERV (energy recovery ventilator) option. This aluminum door assembly mounts in the vent/door opening to help the unit manage and seal the dedicated ERV ventilation path so the system can control outside air flow as intended and maintain proper cabinet separation during operation. Replacing a bent, corroded, or leaking vent option door helps restore correct ventilation performance and reduces unwanted air leakage that can affect comfort and efficiency. Confirm compatibility by matching S553-558 to your Bard parts list for the specific model and vintage before ordering.
