Modine 5H0630350001 Fan Blade

When you are dealing with a vibration issue or reduced static pressure in a Modine PA50 unit heater, the Modine 5H0630350001 Fan Blade is the exact OEM replacement part required to restore factory-spec airflow. As a direct 5H63035-1 replacement, this 3-blade aluminum propeller is engineered for precise balance and aerodynamic efficiency. It features an 11 3/4-inch diameter and a 0.3125-inch (5/16") shaft bore, secured via a single set screw for a reliable mechanical connection to the motor shaft. Replacing a fatigued or pitched blade is critical to preventing bearing failure in the fan motor and ensuring the heat exchanger receives the necessary CFM to prevent limit trips. This HVAC replacement fan blade is built to withstand the high-cycle demands of commercial and residential garage heating applications, maintaining the specific pitch requirement to optimize BTU output and energy efficiency.

• Direct OEM Compatibility: Engineered as the specific Modine 5H63035-1 replacement to ensure zero-clearance issues within the fan guard and orifice.
• Enhanced Vibration Dampening: Factory-balanced aluminum fan blade construction minimizes harmonic resonance, extending the service life of the motor bearings.
• Optimized Airflow Profile: The 3-blade design is tailored for Modine unit heater parts, providing consistent static pressure across the heat exchanger.
• Reliable Mechanical Fit: Precision-machined 5/16" bore with a heavy-duty set screw prevents slippage during high-torque startup cycles.

• How do I verify if this blade fits my specific Modine heater? This part is the standard propeller replacement for the PA50 and select Hot Dawg unit heaters. Always check the original part number stamped on the blade or your unit's data plate before installation.
• Can I use an aftermarket blade with the same diameter? While dimensions may match, OEM fan blades like the 5H0630350001 have specific pitch angles designed for the motor's RPM and the unit's thermal requirements. Using an incorrect pitch can overheat the motor or reduce heating capacity.
• What tools are needed for the replacement? A standard hex key (Allen wrench) is required for the set screw, though a hub puller may be necessary if the original blade has seized to the motor shaft due to oxidation.
