The Nordyne 1025340R Fan Blade 18” 3 Blades 1/2” Bore CW is an essential accessory of HVAC systems that helps in increasing the flow rate of air and efficiency. This three-bladed fan blade is 18" in diameter and 1/2" bore, and is standard in many Nordyne furnaces and air handlers. Its main purpose is to blow air around the system in order to regulate temperature and maximize cool down. The fan blade design and rotation (clockwise) enhances the air flow and thus the energy utilization, reduced noise and comfortable indoor environment.

HVAC air-moving assemblies use fans to provide the mechanical movement required for airflow through the associated system. The Nordyne 1025340R is a fan used within an associated fan assembly to provide mechanical air movement. It serves as the air-moving component within the system, where the rotating blade assembly supports the required airflow function.

3-Blade Fan Design:
The fan generates mechanical air movement as its blade assembly rotates. The arrangement of the blades determines how the assembly interacts with the surrounding air during operation, supporting the fan's airflow function within the associated system.

Clockwise Rotation and Mechanical Connection:
The fan's specified rotational direction determines the direction in which the blade assembly moves during operation. The bore provides the mechanical connection point between the fan and the associated drive assembly, allowing the fan to receive the rotational movement required for air movement.

Replacement Guidelines:
Replacement may be appropriate when the existing fan is physically damaged, deformed, no longer operates as intended, or no longer provides its intended air-moving function. For the Nordyne 1025340R, replacement may be appropriate when the fan can no longer perform its intended mechanical role within the associated fan assembly.

Common Failure Symptoms:

  • The fan does not rotate as expected.
  • Blade movement becomes uneven during rotation.
  • The fan develops noticeable vibration while rotating.
  • Unusual noise occurs during operation.
  • The blades show visible damage or deformation.

Equipment Compatibility:
The Nordyne 1025340R 3-Blade Fan should be selected for applications requiring the corresponding fan configuration. Before purchasing, verify the existing 1025340R part number, connected drive arrangement, and applicable system requirements against the original equipment documentation.

Product Questions (12)
Customer Questions
What maintenance is required for the Nordyne 1025340R 3-Blade Fan?

Regularly clean the fan blades to remove dust, debris, or buildup that could unbalance the fan. Inspect the bore and mounting for wear or looseness. Ensure proper rotation and secure fasteners. Routine maintenance prevents vibration, extends blade life, and maintains airflow efficiency.

What are common issues with the Nordyne 1025340R 3-Blade Fan?

  • Reduced airflow due to dust or debris buildup.
  • Unusual buzzing or vibration noises.
  • Loose or misaligned mounting affecting operation.
  • Blade damage or imbalance reducing efficiency.

In what way does blade geometry affect performance?

Blade shape and pitch influence the aerodynamic interaction with surrounding air, helping establish the direction and distribution of the resulting airflow.

Which part of the fan transfers drive force?

The central hub and shaft interface receive mechanical rotation from the connected drive and transfer that movement to the blade assembly.

Why is rotational alignment important during operation?

Proper alignment keeps the rotating assembly centered around its drive axis, supporting stable movement and consistent mechanical operation.

What happens to airflow as the fan blade rotates?

The rotating blade surfaces displace surrounding air and guide it through the designated airflow path within the connected assembly.

How can I confirm the 1025340R fan blade before purchasing?

Match the 1025340R designation and fan-blade identification with the existing component and applicable air-moving assembly information.

What type of fan is the Nordyne 1025340R?

The Nordyne 1025340R is a 3-blade fan used as the rotating air-moving component within an HVAC fan assembly.

How does the 1025340R fan produce mechanical airflow?

As the blade assembly rotates, its blades interact with the surrounding air and create movement through the connected air path.

What does the clockwise rotation specify on the 1025340R?

The clockwise (CW) designation specifies the required direction of blade rotation during operation.

What does the 1/2-inch bore provide on the fan?

The 1/2-inch bore provides the mechanical connection point through which the fan attaches to the associated drive shaft.

What should be checked before selecting the 1025340R?

Compare the existing 1025340R part number and fan configuration with the original equipment documentation before ordering.

Installation Steps

Step1: Turn off power to the unit at the breaker to prevent electrical shock.

Step2: Remove the old fan, noting blade orientation and mounting hardware.

Step3: Slide the new fan onto the 1/2" motor shaft, ensuring correct clockwise rotation.

Step4: Secure the fan with set screws or mounting hardware.

Step5: Check that the fan spins freely without obstruction.

Step6: Restore power and test the unit to ensure proper airflow.
