Mestek j34r06999-104 Fan Blade Propeller Xf Series

Product Description

The MESTEK j34r06999-104 is a replacement fan blade propeller designed for use in XF Series unit heaters and ventilation equipment. This component drives airflow through the heat exchanger or discharge assembly, maintaining proper air movement for effective space heating. HVAC technicians and commercial heating service professionals install this part during routine maintenance or when replacing a damaged or failed fan blade. The propeller must be matched to the correct shaft size and rotation direction before installation to ensure proper airflow balance and system performance.

This fan blade propeller is specifically intended for MESTEK XF Series models in the 100-150 and 300 capacity ranges. These unit heaters are commonly found in commercial and light industrial applications such as warehouses, garages, and manufacturing facilities. When the original blade shows cracks, chips, or balance issues, this OEM-style replacement restores proper airflow and prevents motor strain caused by unbalanced rotation.
