The Bard 139-226BX ERV Exhaust Blade (boxed) is an OEM replacement fan blade used in Bard energy recovery ventilator exhaust sections to move stale air out of the building while supporting balanced ventilation performance. Replacing a bent, cracked, or out of balance exhaust blade helps restore proper exhaust airflow, reduces vibration and noise, and protects the ERV blower motor from unnecessary strain. This part is intended to match Bard fit and operating requirements, so it is a dependable choice when servicing Bard wall mounted ventilation packages where correct airflow is critical for comfort and indoor air quality. Confirm compatibility by referencing your Bard unit model and ERV parts breakdown before ordering.
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.
