The Bard 5152-012BX blower wheel is an OEM centrifugal wheel built to restore proper airflow through the indoor blower section of compatible Bard wall mount and packaged HVAC units. This wheel is specified for counterclockwise rotation with a 1/2 inch bore and a nominal 10 inch diameter by 8 inch width, helping the blower assembly move the correct volume of air across the coil for stable cooling, heating, and dehumidification performance. If your unit has reduced airflow, unusual vibration, or a damaged wheel hub or fins, replacing with the correct Bard part number is the safest way to maintain proper fit on the motor shaft and keep the blower balanced to factory specifications.
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.
