239380 - Miller High-Output Muffin Fan 24VDC 141 CFM

Reliable Thermal Management for Industrial Welding Equipment

Maintaining the optimal operating temperature of your welding power source is critical for longevity and performance. The Miller 24VDC Muffin Fan is a genuine OEM replacement component designed to provide robust cooling for compatible Miller welding machines. Engineered to meet the rigorous demands of industrial environments, this fan ensures that internal components such as transformers, rectifiers, and circuit boards remain within safe thermal limits during extended welding operations.

This high-efficiency axial fan operates at 24 Volts DC, a standard control voltage in many modern welding power sources. With a rotational speed of 3200 RPM, it generates a substantial airflow of 141 Cubic Feet per Minute (CFM). This high volume of air movement is essential for rapidly dissipating heat generated during the welding process, preventing thermal overload shutdowns and protecting sensitive electronics from heat-induced failure. The fan's ability to move air effectively through the machine's chassis ensures consistent performance even in warm shop environments.

Installation is straightforward thanks to the standard 4.125-inch mounting centers, which align with the chassis mounting points of compatible equipment. The unit measures 5.00 inches in width and length with a depth of 1.75 inches, making it a compact yet powerful solution for internal cooling. Weighing approximately 11 ounces, it adds minimal weight to the overall system while providing maximum cooling efficiency.

Using genuine Miller replacement parts like this muffin fan guarantees compatibility and reliability. Generic fans may not match the specific airflow pressure curves or electrical characteristics required by your welder, potentially leading to inadequate cooling or electrical issues. By choosing the correct OEM part, you ensure that your equipment continues to operate at the factory-specified standards, minimizing downtime and extending the service life of your investment.
