The Bard 5151-043BX fan blade is a 24 inch, boxed, 3 blade propeller designed for counterclockwise rotation, making it a direct-fit replacement when you need to restore proper condenser airflow on compatible Bard wall-mounted and packaged HVAC units. A worn, bent, or unbalanced blade can reduce heat rejection and lead to high head pressure, added noise, and poor cooling performance, so replacing it with the correct OEM blade helps protect the compressor and bring the system back to normal operation. Confirm diameter, rotation direction, and hub/bore requirements against your Bard model and parts manual before ordering to ensure proper fit and safe, vibration-free operation.
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.
