213072 - Miller Coolmate Replacement Muffin Fan 115V 3400 RPM

Genuine Miller 213072 Muffin Fan for Coolmate Systems

The Miller 213072 Muffin Fan is a critical replacement component designed specifically for the maintenance and repair of Miller Coolmate coolant systems. Engineered to meet the exact specifications of the original equipment, this high-performance axial fan operates at 115 Volts and 60 Hz, delivering a consistent speed of 3400 RPM. This specific rotational speed is calibrated to provide optimal airflow through the radiator of the cooling unit, ensuring that the coolant temperature remains within the safe operating range for TIG torches and MIG guns. Overheating in liquid-cooled systems can lead to catastrophic failure of the torch or the pump, making the functionality of the cooling fan paramount.

This replacement fan features specific mounting dimensions, noted as 6.378 mounting holes, which ensures a drop-in fit for compatible units without the need for modification or adapters. It is verified for fitment with the Coolmate 3.5, Coolmate 1 CE, and Coolmate 1 Non-CE models. Using genuine Miller parts like the 213072 guarantees that the electrical connectors and physical footprint match the internal chassis of the cooler. The fan is built to withstand the industrial environments often found in welding shops, resisting dust and debris accumulation that can plague lesser quality generic fans.

When a cooling fan fails, symptoms often include increased coolant temperatures, thermal shut-off of the welding power source, or unusual noises coming from the cooler unit. Replacing a faulty fan immediately is essential to prevent downtime and protect expensive water-cooled torches. This unit is sold as a single package containing one fan assembly. It does not typically include mounting screws, so retaining the original hardware during disassembly is recommended. Whether performing routine maintenance or an emergency repair, the Miller 213072 provides the reliability professional welders expect from the Miller Electric brand.

By maintaining your Coolmate system with authentic parts, you ensure the longevity of your welding setup. The 115V configuration is standard for these auxiliary cooling units, drawing power directly from the cooler's internal power distribution. Trust in the engineering of Miller to keep your heavy-duty TIG and MIG applications running cool and efficient.
