Modine 5H0706770004 OEM Replacement Fan Blade Bore for Unit Heaters - 1/2

The Modine 5H0706770004 is a genuine OEM replacement fan blade designed for use in Modine unit heaters. Featuring a 1/2" bore, this axial propeller fan blade mounts directly to the motor shaft and delivers consistent, calibrated airflow across the heat exchanger to maintain the unit's original thermal performance.

As a factory-specified replacement component, the 5H0706770004 matches the precise blade pitch, diameter, and hub geometry of the original part — ensuring proper shaft alignment, correct CFM output, and balanced operation. Using a genuine Modine fan blade prevents the motor overloading and premature bearing wear that can result from improperly pitched universal replacements.

Key Features:

• Genuine Modine OEM replacement fan blade
• 1/2" bore for direct motor shaft fitment
• Engineered blade pitch maintains original airflow and BTU performance
• Precision balance minimizes vibration and reduces wear on motor bearings
• Compatible with Modine gas-fired, hydronic, and other unit heater configurations
• Direct drop-in replacement — no modification required

Always verify the part number against your unit's data plate before ordering. Replacing a cracked, bent, or vibrating blade with this genuine Modine component restores safe and efficient heater operation.
