K4259-4 - Lincoln Prism Mobile Fume Extractor One-Pak with 13ft Arm & MERV 14 Filter

Industrial-Grade Fume Control for Safe Fabrication Environments

The Lincoln Electric Prism® Mobile One-Pak® (K4259-4) represents a robust solution for maintaining air quality standards in light to medium-duty welding environments. Designed to meet the rigorous demands of industrial fabrication shops, maintenance departments, and educational facilities, this mobile low-vacuum system effectively captures and filters welding fumes at the source. By removing particulate matter before it enters the operator's breathing zone or settles on sensitive equipment, the Prism Mobile helps facilities comply with occupational safety regulations and maintain a cleaner, more productive workspace.

High-Efficiency MERV 14 Filtration

At the core of the K4259-4 system is a high-capacity MERV 14 filter. With a substantial surface area of 538 square feet, this filter is engineered to capture fine welding particulates with exceptional efficiency. The large surface area not only ensures superior filtration performance but also significantly extends the service life of the filter cartridge. This design choice translates to lower operational costs over the lifespan of the unit, as filter changeovers are required less frequently compared to standard mobile units. A built-in filter status indicator provides operators and maintenance personnel with a clear visual guide to the remaining filter life, allowing for proactive maintenance planning.

Versatile Reach and Positioning

This One-Pak® configuration includes the K2633-7 Fume Extraction Arm, which offers an impressive 13-foot reach. This extended length allows the extraction hood to be positioned precisely where it is needed, even in challenging or obstructed work areas. The arm is designed for flexibility and stability, holding its position once set to ensure continuous fume capture without constant readjustment. The mobile base unit sits on sturdy front casters and large rear wheels, making it easy to maneuver the 297-pound unit between workstations or into storage when not in use.

Safety and Durability Features

Lincoln Electric has integrated critical safety features into the Prism Mobile. An internal spark arrestor acts as a pre-filter, catching larger particles and preventing sparks from reaching the main filter element, thereby reducing fire risks. The unit operates on standard 120V single-phase power, drawing only 6.1 amps, making it compatible with standard shop outlets without requiring specialized electrical installation. The system delivers a generous airflow of 750 SCFM, ensuring that smoke and fumes are pulled away from the weld zone effectively. Backed by a 3-year warranty, the Prism Mobile is a reliable investment for any facility prioritizing welder safety and environmental health.
