Heil Quaker ICP 1113971 Fan Blade

The Heil Quaker ICP 1113971 Fan Blade is a critical HVAC replacement part engineered for high-efficiency condenser units. Featuring a 22-inch diameter and a 21-degree pitch, this 4-blade fan is designed to move significant air volume while maintaining low static pressure. As a genuine OEM fan blade, it ensures proper balanced rotation, which is essential for protecting the motor bearings from premature wear caused by vibration. The counter-clockwise (CCW) rotation and 5/8-inch bore allow for a precise fit on standard motor shafts found in Heil, Tempstar, and Comfortmaker packaged units and air conditioners. Technicians should verify the intake side hub orientation to ensure optimal condenser airflow performance. Replacing a bent or corroded blade with this ICP 1113971 model restores factory-spec cooling efficiency and prevents system overheating. For a successful install, always check the set screw torque to prevent slippage during high-speed operation.

• OEM Compatibility: Exact drop-in replacement for Heil Quaker, Arcoaire, and KeepRite systems.
• Precision Balance: 4-blade design reduces mechanical stress on the condenser fan motor.
• Durable Construction: Engineered to withstand harsh outdoor environments without losing its 21-degree pitch.
• Optimized Airflow: Technical CCW rotation configuration ensures maximum heat extraction from the condenser coil.

How do I confirm the rotation of my existing fan blade?
View the fan from the discharge (top) side; this model is a CCW rotation. Always match the rotation of your original 1113971 to avoid reversing airflow and overheating the system.

Will this fit a 1/2-inch motor shaft?
No, this specific part features a 5/8-inch bore. If your motor has a 1/2-inch shaft, you would require a different part number or a shaft bushing, though a direct OEM fit is always recommended.

When should I replace my condenser fan blade?
Replace immediately if you notice visual stress cracks near the hub, corroded blades, or if the system produces excessive wobbling or metallic rattling noises during the cooling cycle.
