Miller 24V DC Muffin Fan Replacement, 310 CFM High Output

Keep Your Welder Running Cool and Efficient

Is your welder overheating or shutting down unexpectedly? A faulty cooling fan is often the culprit. The Miller 225166 Muffin Fan is the direct replacement you need to get your machine back up and running smoothly. Welding generates a significant amount of heat, and without a functioning fan, your power source cannot maintain its rated duty cycle. This leads to frustrating downtime and potential damage to expensive internal components. This genuine Miller replacement part is designed to drop right into place, ensuring your welder stays cool even during long, high-amperage welds.

This powerful 24V DC fan spins at 4000 RPM, pushing an impressive 310 CFM of air through your machine. That high volume of airflow is essential for pulling heat away from critical parts like the transformer and inverter board. The mounting holes are spaced exactly 6.378 inches apart, matching the original configuration of your Miller equipment perfectly. This means no drilling, no guessing, and no hassle—just a straightforward swap that restores your welder's cooling system to factory performance.

Don't risk frying your welder's electronics by ignoring a noisy or stopped fan. Symptoms of a bad fan include unusual grinding noises, the fan not spinning when the machine is on, or the thermal overload light coming on frequently. Replacing the fan is a cost-effective repair that protects your investment. Trust in genuine Miller parts to provide the longevity and reliability you expect from your equipment. With the 225166 fan installed, you can focus on laying down perfect beads, knowing your machine is protected against thermal overload.
