CK0901-48 - Lincoln Mobiflex 400-MS Fume Extractor with 13ft LFA 4.1 Arm

Breathe Easy with the Mobiflex 400M

Welding safety is paramount, and the Lincoln Electric Mobiflex 400M (CK0901-48) is designed to keep you breathing clean air while you work. This all-in-one package combines the proven performance of the Mobiflex 400-MS mobile filtration unit with the impressive reach of the LFA 4.1 extraction arm. It is the ideal companion for professional welders who need a reliable "smoke eater" that can move with them around the shop. By capturing fumes at the source, you not only protect your own health but also improve visibility of the weld puddle and keep your workspace cleaner.

Superior Reach and Flexibility

One of the standout features of this package is the LFA 4.1 arm. While standard arms might limit your movement, the LFA 4.1 offers a reach of approximately 13 feet (4 meters). This means you can work on large assemblies, move around a jig, or switch between two nearby workstations without dragging the heavy base unit with you every time. The arm is counterbalanced for smooth positioning—it stays where you put it—and features a rotatable hood that can be angled to catch fumes effectively regardless of the welding position. The pre-wired design means less hassle during assembly; you get to work faster.

Efficient and Quiet Operation

Nobody wants a roaring machine drowning out the shop environment. The Mobiflex 400M operates at a comfortable 69 dBA, allowing for normal conversation and better situational awareness while the unit is running. Despite its quiet operation, it pulls a robust 735 CFM of airflow through the arm, ensuring that smoke is pulled away from your breathing zone rapidly. The large capacity filter cartridge is designed for longevity, and the built-in filter status indicator lets you know exactly when it's time for a swap, preventing you from working with a clogged system.

Built for the Welder

This unit is optimized for the realities of a welding shop. It handles dry welding fumes efficiently and includes a spark arrestor to prevent fire hazards within the filter housing. The rugged chassis is mounted on heavy-duty wheels, allowing you to roll it over cables and cracks in the floor with ease. Whether you are MIG welding mild steel or TIG welding stainless, the Mobiflex 400M provides the localized exhaust ventilation you need to stay safe, compliant, and productive.
