Heil Quaker ICP 1085684 Fan Blade

The Heil Quaker ICP 1085684 Fan Blade is a critical direct-drive component engineered for specific condensing unit airflow requirements in residential HVAC systems. This 18-inch diameter replacement fan blade features a precision-engineered 22-degree pitch and a 2-blade configuration designed to maintain optimal static pressure while minimizing motor load. Constructed for clockwise (CW) rotation, the assembly includes a 1/2-inch bore positioned on the intake side, ensuring a secure fit on standard PSC or ECM motor shafts. When troubleshooting ICP replacement parts for Heil, Tempstar, or Comfortmaker units, verifying the pitch and rotation is essential to prevent compressor overheating or premature motor failure. This OEM-spec fan blade ensures the heat exchanger operates within designed thermal parameters by providing consistent CFM output. Its durable construction resists blade deformation under high-velocity operation, making it a reliable choice for field service technicians performing condenser fan motor repairs on legacy and modern ICP equipment.

Key Technical Benefits:

• OEM Compatibility: Precision-balanced to meet original Heil Quaker performance curves, reducing vibration and extending motor bearing life.
• Optimized Airflow: The 22-degree pitch is tuned for efficient heat rejection in high-ambient conditions.
• Durable Construction: High-grade materials prevent blade "flutter" and maintain structural integrity during heavy-duty HVAC operation.
• Direct Fitment: The 1/2-inch hub allows for rapid installation on standard condenser motor shafts without field modification.

Common Questions:

What happens if I install this fan blade with the wrong rotation?
Installing a CW rotation blade in a CCW application will cause the air to move in the wrong direction, leading to a rapid rise in head pressure and potential compressor lockout or failure.

Does the bore diameter support universal motors?
This blade utilizes a 1/2-inch bore, which is the industry standard for most residential condenser fan motors. Always check the motor shaft diameter with a caliper before installation.

Why is the 22-degree pitch significant for this model?
The pitch determines how much air is moved per revolution. Using an incorrect pitch can overload the motor windings or fail to pull enough air through the condenser coils, reducing SEER efficiency.
