International Comfort Products 1176937 Blower Wheel 11" DIA X 11" W 1/2" Bore

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 ...

Clean the blower wheel regularly to remove dust and debris that can reduce airflow efficiency. Inspect for cracks, bent fins, or imbalance that may cause vibration. Ensure the bore remains securely fitted on the shaft and check alignment to prevent motor strain and premature damage.

• Excessive vibration caused by an unbalanced or damaged blower wheel.
• Reduced airflow from dirt buildup or bent wheel fins.
• Squealing or rattling noises due to loose mounting or worn components.
• Wheel slippage on the motor shaft causing inconsistent airflow performance.
