The Multiquip 1727474110 Fan is a genuine OEM Fan designed for the BLW-400SSW welder. Sourced directly from Multiquip, this fan is built to the exact specifications of the original component, ensuring a correct, hassle-free installation. If your BLW-400SSW is running hot or showing signs of inadequate airflow, replacing the fan with the correct OEM part is the reliable path to restoring proper thermal management.
Key Features
- OEM-Grade Airflow Performance — Manufactured to Multiquip's original blade pitch, diameter, and balance specs, delivering the correct cubic feet per minute of airflow the BLW-400SSW's cooling circuit demands.
- Drop-In Installation — Matches the original mounting configuration and shaft interface on the BLW-400SSW, so installation is straightforward with standard hand tools.
- Confirmed Fitment for BLW-400SSW — Verified against the BLW-400SSW welder model, so you can order with confidence that this part is the right fan for your machine.
- Protects Internal Components from Heat Damage — A correctly functioning fan maintains safe operating temperatures inside the welder enclosure, protecting transformer windings, rectifiers, and control boards from thermal stress.
- Genuine OEM Quality — As a genuine Multiquip part, this part meets the same material and performance standards as the fan your machine left the factory with.
The fan in a welder like the BLW-400SSW is responsible for drawing air across internal heat-generating components — primarily the transformer and rectifier assembly — to prevent thermal buildup during sustained welding operations. Without adequate airflow, internal temperatures rise rapidly, which can trigger thermal overload shutdowns or, in severe cases, cause permanent damage to electrical components. A worn, cracked, or seized fan blade reduces airflow volume, leading to overheating symptoms even during light-duty use. Replacing a failed fan promptly with the correct part keeps the machine operating safely within its designed thermal envelope.
