291630 - Miller 24V DC High-Speed Cooling Fan 352 CFM

Keep Your Welder Cool and Running Smoothly

Hey friends, we all know that heat is the enemy of electronics, especially when you are pushing your welding machine to its limits on a long shift. That is why the cooling system in your power source is absolutely critical. If your fan has quit on you, or if it is starting to make that dreaded grinding noise, it is time to swap it out before you cook your boards. This Miller 291630 Muffin Fan is the genuine article, designed specifically to keep the air moving and the temperatures down inside your valuable equipment.

This isn't just some generic computer fan you pick up at an electronics store. This is a heavy-duty, 24V DC industrial fan that cranks out 352 CFM of airflow. That is a serious amount of air moving through your machine to dissipate heat from the rectifier and transformer. Running at 4500 RPM, it is built to handle the demands of a welding shop environment. I always tell people: stick with OEM parts for cooling. Miller engineers designed the airflow path in your machine based on the specific pressure and volume this fan delivers. Using a weaker aftermarket fan might save a few bucks now, but it could cost you a main board later.

Installation is generally straightforward since it is a direct replacement part. The mounting holes are spaced at 6.378 inches, so it drops right into the existing bracketry of compatible machines. Whether you are doing a preventative maintenance overhaul or an emergency repair to get back up and running, this fan is the reliable choice. Don't risk your machine's duty cycle or longevity on a sub-par cooling solution. Grab this genuine Miller fan and keep your arc stable and your machine happy.

Remember to always disconnect power before opening up your machine case, and if you aren't sure if this is the exact part number for your specific serial number, give us a shout or check your manual. We want to make sure you get the right part the first time so you can get back to burning rod.
