K4384-8 - Lincoln Prism Mobile Fume Extractor One-Pak with 13ft Arm & Arc Sensor

Technical Overview of the Lincoln Prism Mobile One-Pak

The Lincoln Electric Prism® Mobile with Mechanized Cleaning (K4384-8) is a comprehensive low-vacuum fume extraction system designed for industrial environments requiring mobility and high-efficiency filtration. This "One-Pak" configuration simplifies procurement by bundling the base unit with a 13-foot flexible extraction arm, a MERV 16 filter, and an Arc Sensor/Lamp Kit. The system is engineered to deliver a generous airflow of 735 CFM at the hood, ensuring effective capture of welding fumes at the source. The unit is particularly well-suited for light to medium-duty welding applications in fabrication shops, maintenance departments, and training centers.

At the core of the Prism Mobile's performance is the RotaPulse® Automatic Filter Cleaning system. This mechanized feature utilizes compressed air pulses to dislodge particulate matter from the filter media, depositing it into a collection bin. This process significantly extends the operational life of the KP1653-5 MERV 16 filter, maintaining optimal airflow for longer periods and reducing the frequency of manual maintenance or filter replacement. The MERV 16 rating ensures the capture of ultra-fine particulates, returning cleaner, filtered air to the facility environment.

Safety and operational efficiency are enhanced by the inclusion of an internal spark arrestor and the Arc Sensor/Lamp Kit. The spark arrestor functions as a pre-filter, capturing larger particles and preventing sparks from reaching the main filter element, thereby mitigating fire risks. The Arc Sensor automatically detects the welding arc flash, triggering the vacuum motor to start immediately and stopping it after a preset delay when welding ceases. This automation conserves energy and reduces noise levels when the unit is not in active use. The 13-foot extraction arm (K2633-7) provides an extended reach, allowing operators to position the hood precisely over the weld zone without constantly moving the base unit.
