K2497-3 - Lincoln Electric SF2400 Replacement Fan Assembly 1HP 230V/50Hz

Technical Overview of the Lincoln Electric K2497-3 Fan Assembly

The Lincoln Electric K2497-3 is a specialized fan assembly engineered specifically for the SF2400 stationary fume extraction system. In industrial maintenance, repair, and operations (MRO), ensuring the continuous functionality of environmental safety equipment is paramount. This unit features a robust 1HP motor configured for 230V, single-phase, 50Hz power inputs, making it a critical component for facilities operating on this specific electrical standard. The assembly is designed to integrate seamlessly with the SF2400 housing, restoring the system's original performance specifications without the need for extensive retrofitting or adaptation.

A key engineering feature of this fan is its impeller design. It utilizes self-cleaning concave blades, a significant advantage in welding environments where particulate matter and metallic dust are prevalent. Standard fan blades can accumulate heavy debris over time, leading to imbalance, reduced airflow, and eventual motor failure. The self-cleaning geometry of the K2497-3 impeller mitigates this accumulation, maintaining a consistent unrestricted airflow of 1200 CFM. This consistent static pressure is vital for capturing welding fumes at the source before they disperse into the ambient facility air.

Installation of the K2497-3 requires a compatible mounting bracket (sold separately or reused from the existing installation). MRO specialists should verify the facility's voltage and frequency requirements (230V/50Hz) prior to procurement, as this differs from standard 60Hz North American configurations. By utilizing genuine Lincoln Electric replacement parts, facility managers ensure that the thermal overload protections and airflow dynamics of the SF2400 system remain within manufacturer tolerances, safeguarding both the equipment and the personnel relying on it for respiratory protection.
