This component moves air across the heat exchanger to deliver conditioned airflow into the space. It is a direct mechanical replacement intended for technicians servicing MESTEK and Sterling-branded unit heaters in commercial and industrial heating applications. Proper airflow performance depends on a structurally sound, correctly pitched blade, making this a critical replacement part when blades show signs of damage, imbalance, or wear.\u003c\/p\u003e\n\u003cp\u003eThis fan blade propeller is specifically called out for XF Series unit heaters at the 175K and 350K BTU\/h capacity ratings. These unit heaters are commonly found in warehouses, garages, manufacturing facilities, and other large-volume commercial or industrial spaces where forced-air heating is required. Installation is performed by qualified HVAC technicians during routine maintenance or as part of a component-level repair on an existing unit heater assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement fan blade propeller for XF Series unit heaters\u003c\/li\u003e\n  \u003cli\u003eCompatible with both 175K and 350K BTU\/h capacity models\u003c\/li\u003e\n  \u003cli\u003eDesigned for forced-air unit heater applications in commercial and industrial settings\u003c\/li\u003e\n  \u003cli\u003eOEM-specified part number ensures correct fit within the XF Series fan assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use with MESTEK XF Series unit heaters at 175K and 350K BTU\/h capacity ratings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Before servicing the fan assembly, disconnect and lock out all electrical power to the unit heater in accordance with NFPA 70 (NEC) and local codes. Ensure the replacement blade is fully seated and secured on the motor shaft before restoring power. Do not operate the unit with a damaged or improperly mounted blade, as imbalance can cause premature motor bearing failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: XF Series Unit Heaters, 175K and 350K BTU\/h\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Fan Blade Propeller\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MESTEK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: j34r06999-105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MESTEK","offers":[{"title":"Default Title","offer_id":51233483456818,"sku":"J34R06999-105","price":277.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633385.jpg?v=1780101072","url":"https:\/\/voomisupply.com\/products\/mestek-j34r06999-105-fan-blade-propeller-xf-series","provider":"Voomi Supply","version":"1.0","type":"link"}
