Fasco 4CR1633-4 Fan Blade
The Fasco 4CR1633-4 is a heavy duty condenser fan blade engineered for high-static pressure applications in residential and commercial HVAC units. Featuring a 16-inch diameter and a 33-degree pitch, this 4-blade aluminum fan is designed to move significant air volume while maintaining structural integrity under load. The unit is configured for Clockwise (CW) rotation (viewed from the discharge side) and features a 1/2" bore located on the intake side for secure shaft mounting. This replacement condenser fan blade is a standard solution for restoring OEM airflow specifications in outdoor condensing units where heat dissipation is critical. When performing a Fasco fan blade replacement, ensure the pitch and rotation match the motor's requirements to prevent over-amping or insufficient cooling. This HVAC propeller fan is built for durability, resisting the corrosive effects of outdoor environments while ensuring balanced operation and reduced vibration within the blower assembly.
Key Performance Benefits
- Optimized Airflow: The 33-degree pitch is specifically calibrated for condenser coils requiring high CFM output.
- Industrial Build: Heavy-duty construction ensures the blades resist flexing or warping during high-RPM operation.
- Precision Balance: Factory-set tolerances minimize bearing wear on the condenser motor, extending the life of the drive system.
- Standard Compatibility: The 1/2-inch hub diameter fits most standard 48-frame and 56-frame outdoor motors.
Common Installation Questions
How do I determine the rotation of the Fasco 4CR1633-4?
This blade is rated for CW rotation. In the HVAC industry, rotation is typically determined by looking at the discharge side of the blade. Always verify the motor lead configuration before installation.
Does the bore intake side location matter?
Yes. The intake side hub location is critical for proper alignment within the venturi or fan shroud. Ensure the set screw is torqued to spec on the flat portion of the motor shaft.
Can I use this for an evaporator application?
While physically possible if dimensions match, this is a condenser-style blade designed for pushing air through restrictive coils rather than low-static evaporator environments.
