Armstrong Furnace R45582-001 Fan Blade

The Armstrong Furnace R45582-001 Fan Blade is an OEM condenser fan blade engineered for efficiency in residential and commercial split-system condensing units. This 18-inch fan blade features a 3-blade configuration designed to optimize airflow across the coil while maintaining low vibration levels to prevent mechanical fatigue on the condenser motor. Built with a 1/2-inch hub diameter and a specific clockwise rotation, it ensures precise fitment on standard HVAC blower motors. High-grade aluminum construction provides the necessary rigidity and corrosion resistance required for outdoor exposure. When replacing a damaged HVAC fan blade, maintaining the original pitch and diameter is critical to prevent excessive amp draw and motor overheating. This genuine Armstrong replacement part restores static pressure performance and thermal heat transfer efficiency, ensuring the refrigerant cycle operates within specified pressure parameters during high-load conditions.

Key Benefits:

• OEM Precision: Direct replacement for Armstrong R45582-001 to ensure balance and system compatibility.
• Durable Construction: Heavy-gauge aluminum blades engineered for long-term HVAC airflow stability.
• Optimal Airflow: 3-blade design reduces turbulence and acoustic signatures during operation.
• Standard Fitment: Integrated 1/2-inch bore hub for secure mounting to common motor shafts.

Common Questions:

What is the diameter and rotation of this fan blade?
The R45582-001 measures 18 inches in diameter and is designed for specific rotation patterns matched to Armstrong and Allied Air equipment.

Will this fit a 1/2-inch motor shaft?
Yes, this unit features a 1/2" hub, which is the standard size for most residential condenser motors.

Why is it important to use an OEM fan blade?
Using an OEM furnace replacement part ensures the motor does not exceed its rated FLA (Full Load Amps) due to improper blade pitch or weight.
