OVERVIEW

Protect Your Shop Air Quality

Keep your welding environment clean and compliant with the Lincoln Electric Prism® Wall Mount Dual-Arm Fume Extractor. This powerful system is the ultimate space-saver for shops with fixed welding stations. By mounting directly to the wall, it keeps your floor clear for equipment and foot traffic while delivering industrial-strength suction right where you need it. With the ability to support two extraction arms, a single unit can cover two welding booths, doubling your efficiency and reducing installation costs.

Save Money on Filters

Stop throwing money away on frequent filter replacements. The Prism® system features a smart, mechanized self-cleaning function. When the filter begins to load with dust, the system cleans itself, shaking off the debris and restoring suction power. This means your MERV 16 filter lasts much longer than standard filters, keeping your operating costs low and your uptime high. The filter itself is huge—offering over 500 square feet of surface area—to trap even the finest welding fumes and smoke.

Built for the Daily Grind

Whether you are running a high-volume fabrication line or a busy welding school, the Prism® is built to take a beating. It includes a built-in spark arrestor to prevent fire hazards and protect the main filter from damage. The unit is designed for easy maintenance with a front-loading door, so you can check or swap parts without wrestling with the machine. Invest in the Prism® Wall Mount to ensure your welders breathe clean air, improving safety, morale, and productivity across your facility.

FAQ

The Prism® Wall Mount Dual Arm unit provides an airflow capacity of 1200 CFM.

This SKU (K3681-2) is the Base Unit. It includes the filtration unit, wall bracket, and connection hoses/flanges. The articulated extraction arms are typically configured separately depending on the reach required (e.g., 10 ft or 13 ft).

It uses a MERV 16 rated filter with Nano technology and a surface area of 568 ft² (52 m²).

The mechanized cleaning system periodically dislodges dust from the filter pleats, usually via compressed air pulses or mechanical agitation, allowing the dust to fall into a collection area and extending the filter's life.

Yes, the MERV 16 filter is highly efficient and suitable for capturing the fine particulates generated during stainless steel welding, helping to maintain safe air quality.

The base unit weighs approximately 355 lbs (161 kg).

The Prism® Wall Mount is designed primarily for indoor use in stationary welding setups. Consult the manual for specific environmental ratings.

Regular maintenance includes emptying the dust collection bin and monitoring the air pressure gauge to determine when the main filter eventually needs replacement.
