The Bard 920-0494 4-6T Full Flow Economizer is an OEM ventilation economizer assembly used on compatible Bard wall-mount HVAC units to bring in outdoor air for free cooling when conditions allow, reducing compressor run time while supporting fresh-air ventilation. Full-flow economizers are commonly applied on telecom and light commercial installations where dependable outdoor air control matters, and this Bard factory part is built to match the unit’s original airflow path and control strategy for proper damper operation and system staging. Verify compatibility by matching your Bard model and serial number and confirming the economizer style and tonnage range before ordering, since economizer packages and harnessing can vary by unit configuration.
