032611 - Miller 14-Inch Aluminum Fan Blade 3-Wing CCW

Reliable Cooling for Industrial Welding Equipment

The Miller 032611 Blade, Fan 14.000 3Wg 23Deg .375 Bore Ccw Al is a critical component designed to maintain the thermal stability of your Miller welding power sources. In industrial environments, welding machines generate significant heat during operation, particularly during high-amperage or high-duty-cycle applications. The cooling system is the first line of defense against thermal overload, which can lead to premature component failure or machine shutdown. This genuine OEM replacement fan blade is engineered to exact factory specifications, ensuring that your equipment operates within its safe temperature range.

Precise Engineering and Specifications

This fan blade features a 14.000-inch diameter and a 3-wing configuration. The blades are set at a specific 23-degree pitch, a design choice calculated to maximize air volume displacement (CFM) while minimizing motor load and noise. The bore size is precision-machined to 0.375 inches (3/8"), ensuring a tight, vibration-free fit on the motor shaft. It is designed for Counter-Clockwise (CCW) rotation; installing a fan with the incorrect rotation direction will reverse airflow, potentially drawing hot air into critical areas rather than exhausting it, or failing to pull cool air over heat sinks effectively.

Durable Aluminum Construction

Constructed from high-grade aluminum, the Miller 032611 offers superior durability compared to plastic alternatives. Aluminum withstands the high ambient temperatures often found inside welding cabinets without warping or becoming brittle over time. Its lightweight nature ensures that the fan motor can spin up to speed quickly without excessive torque, prolonging the life of the fan motor itself. When replacing cooling components, using genuine Miller parts guarantees that the balance, weight, and aerodynamic properties match the original engineering requirements of the machine.

Installation and Compatibility

Failure of a cooling fan is often indicated by unusual noise, vibration, or the machine tripping thermal protection sensors. Replacing a damaged or unbalanced fan blade immediately is essential to prevent costly damage to rectifiers, transformers, and PC boards. Please verify fitment using your machine's serial number to ensure this specific 14-inch, CCW, 0.375-bore blade is the correct part for your model.
