Bard 139-422BX - Exhaust frame
Bard part number 139-422BX is an OEM Exhaust Frame supplied boxed, used on select Bard wall mounted HVAC equipment to provide a rigid mounting and sealing surface for the exhaust air path so the unit can move relief or exhaust air the way it was designed. If your existing frame is bent, corroded, or no longer sealing correctly, replacing it helps restore proper airflow management, reduces air bypass, and supports dependable ventilation performance in classrooms, modular buildings, and telecom or shelter applications where Bard units are common. Confirm fit by matching the part number to your unit model and serial data or the correct Bard parts list before ordering.

What does the "BX" suffix mean?
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.
