• Economizer For D129

Bard part number 920-0389 is an OEM economizer assembly specified for Bard D129 applications, designed to bring in and modulate outdoor air for ventilation and free cooling when conditions allow, helping reduce compressor run time on compatible Bard wall-mount equipment. As a genuine Bard replacement part, it is intended to restore proper damper operation and outdoor air control so the unit can maintain code-required ventilation while economizing under favorable outdoor conditions. Confirm compatibility by matching your unit model and ventilation/economizer option to the Bard parts list or accessory documentation before ordering, since economizer configurations vary by tonnage and control style.
