Bard 139-239BX - Damper Blade

Bard 139-239BX is an OEM damper blade supplied boxed for protection during storage and shipping, used in Bard wall-mount air conditioner and heat pump ventilation assemblies to regulate outdoor air intake and maintain proper airflow control. A worn, bent, or sticking blade can lead to poor ventilation performance, unwanted air leakage, or damper binding, so replacing it with the correct factory part helps restore smooth damper operation and proper unit ventilation. Verify your model and parts breakdown to confirm fit, since Bard uses multiple damper configurations across series and vintages, and this blade must match the correct damper assembly geometry and linkage points.

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.
