The SUPCO fb604 is a replacement fan blade designed for use in HVAC and refrigeration equipment. Fan blades of this type move air across condenser or evaporator coils, maintaining proper airflow for efficient heat transfer. Licensed HVAC technicians and refrigeration service pros install this type of component when an existing blade is cracked, chipped, or out of balance. The fb604 is an OEM-style replacement intended to restore original equipment performance without requiring system modifications.
This fan blade is suited for residential and light commercial HVAC and refrigeration applications. It is typically installed in condensing units, evaporator assemblies, or similar air-moving systems where a direct-replacement blade is required. Consult the equipment manufacturer documentation to confirm correct blade count, diameter, pitch, and hub configuration before installation.
Designed as an OEM-style replacement fan blade for use in compatible HVAC and refrigeration condensing or evaporator assemblies.
Installation should be performed by a licensed HVAC or refrigeration technician. Disconnect and lock out all electrical power to the unit before removing or installing the fan blade. Confirm blade pitch orientation and hub engagement before securing to the motor shaft. Follow applicable local codes and equipment manufacturer guidelines during service.
