Fan Blades

Surplus City Liquidators sources surplus HVAC fan blades directly from manufacturers as overstock. These are brand-new components that came to market because a manufacturer overproduced a run or phased out a product line. These are the same discount AC fan blades you'd purchase through a traditional HVAC distributor, arriving in manufacturer or protective packaging where available. "Surplus" describes how the inventory was acquired, not the condition of the blade.

The collection includes condenser fan blades and axial flow fan blades in a range of configurations: 2-, 3-, and 4-blade assemblies; diameters from 14" to 24" and larger; aluminum, plastic, and metal construction; and pitch angles in the 22-32 degree range. Both clockwise (CW) and counterclockwise (CCW) rotation options are available, with standard 1/2" and 5/8" bore sizes to match common condenser fan motor shafts. Specific models and quantities rotate as manufacturer overstock becomes available, so checking the Fan Blades collection for current listings is recommended before ordering.

The four critical specs for any replacement are HVAC fan blade diameter and pitch, bore size, and rotation direction. Measure diameter from shaft center to blade tip and double it. Bore size must match your motor's shaft diameter exactly (1/2" and 5/8" are the most common). Pitch angle affects airflow volume per revolution relative to your motor's HP and RPM; match the original pitch to avoid overloading or underutilizing the motor. Blade count matters as well: a 3-blade and a 4-blade design of the same diameter move air differently, so match the original count whenever possible.

Yes. When choosing a replacement fan blade, CW or CCW rotation direction is not interchangeable. CW and CCW blades move air in opposite directions, and swapping one for the other on an existing motor will reverse airflow through the condenser or housing. The original equipment design sets the required rotation, and a like-for-like replacement must match it. Rotation direction is listed in each product listing and is typically stamped on or marked on the original blade for easy reference before you order.

It’s generally good practice to consider a condenser fan blade replacement at the same time as the motor, because a worn or out-of-balance blade is a common contributor to motor bearing failure. Replacing both reduces the risk of the new motor being damaged by a blade that does not rotate true. If the existing blade is undamaged, shows no cracks or bends, and checks out for balance, it can typically be reused. When sourcing both parts together, verify the replacement blade's bore size against the new motor's shaft diameter, not just the original motor's.

Many blades in the collection are general surplus AC condenser parts suited to the motor shaft sizes and configurations used across major HVAC brands including Carrier, Trane, Lennox, and Rheem. Because inventory is manufacturer overstock rather than OEM-branded parts, compatibility depends on matching specifications (diameter, bore, pitch, and rotation) rather than brand name or part number alone. Individual product listings include full dimensions and spec details to support verification before ordering.

Surplus City ships fan blades to all 48 contiguous states. Because of their diameter, many blades qualify as oversized items, which affects packaging dimensions and shipping cost calculations. Final charges for freight-class or oversized items may be confirmed by Surplus City's team after the order is placed. Check online for availability of inventory and pickup at our various locations.
