Heatcraft Refrigeration 5101B Fan Blade

For veteran technicians and mechanical contractors, the Heatcraft Refrigeration 5101B Fan Blade is the exact OEM-spec component required to maintain head pressure and thermal exchange in critical refrigeration unit cooling systems. This 5.5-inch diameter, 5-blade assembly features a precise 24-degree pitch, engineered to optimize CFM delivery across condenser coils without placing excessive amperage load on the motor. Designed for CCW (Counter-Clockwise) rotation from the shaft end, the 5101B fan blade and its cross-reference 37377 24 Fan Blade are staples in Bohn and Larkin reach-in unit coolers. With a standard 3/16-inch bore, this blade ensures a seat-tight fit on the motor shaft, preventing the vibration-induced hub fatigue common in generic aftermarket alternatives. When replacing a seized or unbalanced blade, verifying the 5.5-inch diameter and rotation is paramount to avoiding high-pressure cutouts and premature motor bearing failure in commercial applications.

• OEM Compatibility: Precision-balanced to match Heatcraft 5101B and 37377 specifications for Bohn refrigeration parts.
• Optimized Pitch: The 24-degree angle ensures maximum static pressure efficiency in high-ambient environments.
• Direct Shaft Integration: The 3/16" hub diameter provides a secure, slip-free connection to standard evaporator and condenser motors.
• Enhanced Durability: Robust construction withstands the constant cycling found in HVACR refrigeration unit operations.

Does this blade include the set screw?
Most OEM-style hubs come with a factory-installed set screw, but we recommend retaining your existing hardware as a backup during the swap.

How do I verify the rotation direction?
This blade is CCW (Counter-Clockwise) when viewed from the shaft end. Installing a blade with the incorrect rotation will lead to zero airflow and immediate system overheating.

Will this fit 1/4" or 5/16" shafts?
No, this unit is specific to a 3/16" bore. Attempting to bore out the hub or use adapters will compromise the balance and risk shattering the blade under load.
