The Armstrong Furnace R41353-001 Fan Blade is a critical OEM replacement part designed for high-performance air movement in residential and light commercial condenser units. This heavy-duty 23-inch condenser fan blade features a precision-engineered 23-degree pitch across its 3-blade assembly, ensuring optimal static pressure and volumetric airflow for heat exchange efficiency. Built to exacting Armstrong Air standards, this component is configured for Clockwise (CW) rotation and fits standard 1/2-inch motor shafts. Contractors and HVAC technicians rely on the R41353-001 for its robust construction, which minimizes vibration and structural stress on the condenser motor. Replacing a damaged or unbalanced fan blade with this genuine Armstrong furnace part restores factory-spec cooling performance and helps prevent premature motor failure. Always verify the bore size and rotation before installation to ensure total system compatibility and efficient HVAC air circulation.

Key Benefits:

• Precision 23-degree pitch optimized for maximum CFM and heat dissipation.
• Durable 3-blade design engineered to reduce acoustic noise and operational vibration.
• Standard 1/2" bore for seamless integration with existing Armstrong Air motor assemblies.
• Ensures consistent airflow to maintain head pressure within OEM design limits.
• High-grade material construction for reliability in demanding outdoor environments.

Common Questions:

What is the correct rotation for the R41353-001?
This specific fan blade is designed for Clockwise (CW) rotation when viewed from the discharge side (typically the top of the unit).

Can I use this on a 5/8" motor shaft?
No, this part features a 1/2" bore. Attempting to modify the hub will compromise the balance and safety of the assembly.

How do I confirm this fits my specific Armstrong unit?
The most reliable method is to match the part number from your unit's technical data sheet or the stamping on the original blade. This 23-inch diameter blade is a specific fit for select condenser models.
