Reznor 131970 10" 3-Finned Fan Blade Model F125

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Inspect fan blade for dust buildup and clean regularly to maintain balanced airflow. Check for cracks, bends, or deformation in the fins. Ensure secure mounting on the motor shaft and tighten set screws if loose. Verify proper alignment to prevent vibration during operation.

• Imbalanced blade causing vibration or noise.
• Cracked or damaged fins reducing airflow efficiency.
• Loose mounting on motor shaft.
• Reduced airflow due to dirt buildup.
