Bard 920-0449BX is a factory OEM ERV assembly (boxed) built for Bard wall-mounted packaged units in the 3 ton class and intended for 230V applications. This energy recovery ventilator assembly is used to bring in controlled outdoor air while transferring energy between the exhaust and incoming airstreams, helping maintain indoor comfort and ventilation performance without overloading the cooling or heating system. It is a fit-critical ventilation component, so confirm unit model and voltage before ordering to ensure proper compatibility with your Bard ventilation option setup.
* Orders less than $50 may incure a minimum order fee.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
