K4468-12 - Lincoln Prism Wall Mount Dual Arm Fume Extractor One-Pak 230V

Industrial-Grade Fume Extraction for Fixed Workstations

The Lincoln Electric Prism® Wall Mount Mechanized Cleaning One-Pak® (K4468-12) is a premier solution for facility managers seeking to maintain high air quality standards in welding environments with limited floor space. Designed as a stationary, low-vacuum system, this unit is engineered to extract and filter welding fumes efficiently from fixed workstations. The "One-Pak" configuration streamlines the procurement process by bundling the base unit, fans, arms, extensions, and switches into a single, easy-to-order package, ensuring compatibility and reducing installation complexity.

At the heart of the system is a powerful 2 HP motor driving a fan capable of 1750 CFM airflow. This high-volume capture capability is essential for heavy fabrication environments where particulate generation is dense. The unit utilizes MERV 16 Nano Coated Cellulose filters, which are highly effective at trapping sub-micron particles found in welding fumes. A key feature for industrial maintenance is the mechanized cleaning system. Unlike static filters that clog rapidly, the Prism® system periodically pulses or cleans the filter media, dislodging accumulated particulate into a collection bin. This feature maintains consistent airflow over time and significantly extends the lifespan of the filter elements, reducing long-term consumable costs.

The physical configuration of the K4468-12 is tailored for versatility. By mounting to the wall, it frees up valuable floor space for production equipment and material handling. The inclusion of two 14-foot extension cranes coupled with 13-foot flexible arms provides an impressive total reach of 27 feet per arm. This extensive range allows the extraction hoods to be positioned precisely over large weldments or across multiple fixture points without moving the base unit. Ideal for shipbuilding, structural fabrication, and welding schools, the Lincoln Prism® system represents a capital investment in worker safety and regulatory compliance.

Technical Reliability and Compliance

Operating on 230V 3-Phase power, this system is built for continuous industrial duty. The included starter/overload switches provide necessary electrical protection and control. The system's design focuses on "source capture," which is the most effective method for controlling welding fumes as recommended by safety organizations. By removing fumes before they enter the welder's breathing zone or disperse into the general plant air, the Prism® system helps facilities meet OSHA PEL (Permissible Exposure Limits) and ACGIH TLV (Threshold Limit Values) requirements.
