264463 - Miller 370mm 7-Blade Suction Fan for Engine Drives

Genuine Miller Cooling Performance

The Miller 264463 Fan, Engine Cooling 370mm 7 Blade Suction is a critical component designed to maintain the thermal equilibrium of your Miller engine-driven welding machine. In the demanding environments where industrial welders operate, from dusty construction sites to hot fabrication yards, the cooling system is the lifeline of your equipment. This genuine OEM part is engineered specifically to match the shroud dimensions and rotational speed of compatible Miller power sources, ensuring that the engine remains within its optimal operating temperature range.

This fan features a precise 370mm diameter and a 7-blade configuration. The blade pitch and surface area are calculated to move a specific volume of air, providing efficient heat dissipation from the radiator. Unlike generic fans that may fit physically but fail to move adequate air, this Miller component guarantees the static pressure required to draw air through the radiator fins effectively. It utilizes a suction design, meaning it pulls air through the heat exchanger rather than pushing it, a common configuration in compact industrial engine drives to maximize cooling efficiency.

Replacing a damaged fan is not merely a cosmetic repair; it is a preventative measure against catastrophic engine failure. A fan with cracked blades, chipped edges, or imbalance can cause severe vibration, potentially damaging the water pump bearings or the radiator itself. Furthermore, compromised blades reduce airflow, leading to overheating, automatic thermal shutdowns, and reduced duty cycles. By choosing the authentic Miller 264463, you are investing in the longevity of your machine. Always verify fitment with your machine's serial number to ensure this specific 370mm suction fan is the correct match for your model.
