K4259-6 - Lincoln Prism Mobile One-Pak with 10ft Arm and MERV 16 Filter

Industrial-Grade Mobile Fume Extraction

The Lincoln Electric Prism® Mobile One-Pak® (K4259-6) is a comprehensive low-vacuum welding fume extraction system engineered for facility maintenance, fabrication shops, and educational institutions. Designed to address the critical need for air quality control in industrial environments, this unit combines mobility with high-efficiency filtration to capture welding fumes directly at the source. The One-Pak® configuration simplifies procurement by including the base unit, a 10-foot flexible extraction arm, and a complete filter set, ensuring the system is ready for immediate deployment upon arrival.

Advanced MERV 16 Filtration

At the core of the Prism Mobile is its superior filtration capability. The unit is equipped with a MERV 16 (HE) Nano Filter, which provides a minimum efficiency of 95% for contaminants ranging from 0.3 to 1 micron in size. This level of filtration is essential for capturing fine particulate matter generated during MIG, TIG, Stick, and Flux-Cored welding processes. A large filter surface area of 538 square feet ensures a longer filter life and reduced operational costs compared to standard extraction units. Additionally, an internal spark arrestor functions as a pre-filter, capturing larger particulates and preventing sparks from reaching the main filter media, thereby enhancing system safety.

Operational Efficiency and Mobility

The Prism Mobile delivers a robust airflow of 750 SCFM, providing powerful suction to effectively remove smoke and fumes from the welder's breathing zone. The included 10-foot extraction arm features a flexible design with 360-degree rotation, allowing operators to position the hood precisely where it is needed without hindering their workflow. Built for dynamic shop environments, the unit features front casters and large rear wheels, making it easy to maneuver between workstations or into tight spaces. The system runs on standard 120V, single-phase power, eliminating the need for expensive electrical upgrades.

Maintenance and Compliance

Maintenance is streamlined with a color-coded filter status indicator that clearly displays remaining filter life, allowing for planned maintenance schedules rather than reactive downtime. The tool-less main filter replacement system further reduces service time. By integrating the Lincoln Prism Mobile into your operations, you support compliance with OSHA air quality standards and create a safer, cleaner working environment for your team.
