K4259-2 - Lincoln Prism Mobile Fume Extractor One-Pak with 10 ft Arm

Advanced Mobile Fume Extraction for Industrial Environments

The Lincoln Electric Prism® Mobile One-Pak® (K4259-2) represents a robust solution for maintaining air quality standards in manufacturing and fabrication environments. Designed as a low-vacuum system, this mobile unit is engineered to capture welding fumes at the source, preventing the dispersion of hazardous particulates into the general facility atmosphere. The One-Pak configuration simplifies procurement by bundling the high-performance base unit with a flexible 10-foot extraction arm, ensuring immediate operational readiness upon delivery.

High-Efficiency MERV 14 Filtration

At the core of the Prism Mobile system is its substantial filtration capability. The unit utilizes a MERV 14 rated main filter, which is capable of capturing up to 84% of airborne contaminants ranging from 0.3 to 1 micron in size. This level of filtration is critical for operations involving MIG, TIG, Stick, and Flux-Cored welding, where fine particulate matter poses significant respiratory risks. The filter boasts an impressive surface area of 538 square feet, a design choice that not only maximizes particle retention but also significantly extends the service life of the filter, thereby reducing long-term consumable costs.

Operational Efficiency and Safety

The system delivers a generous airflow of 750 SCFM, providing the necessary suction velocity to effectively entrain fumes through the extraction hood. An internal spark arrestor acts as a crucial pre-filter, intercepting larger sparks and particulates before they reach the main filter media, thus mitigating fire risks and protecting the integrity of the filtration system. For maintenance teams, the color-coded filter status indicator offers a clear, visual method for monitoring filter saturation, ensuring that replacements are performed only when necessary to maintain optimal system performance.

Industrial Mobility and Design

Constructed for the dynamic needs of modern workshops, the Prism Mobile features a footprint of 36" x 32" x 48", allowing it to navigate between workstations with ease. Equipped with front casters and sturdy rear wheels, the unit can be positioned precisely where needed. The included 10-foot extraction arm offers a wide range of motion and a 360-degree rotatable hood, enabling welders to position the extraction point effectively without hindering their workflow. Operating on standard 120V single-phase power, this system integrates seamlessly into existing electrical infrastructure without the need for specialized wiring.
