K2751-11 - Lincoln Prism DownFlex 400-MS/A Fume Extraction Table

Industrial Fume Extraction and Workbench Solution

The Lincoln Electric Prism® Down Draft Fume Extraction Table (K2751-11) represents a high-efficiency solution for facility managers and industrial safety officers seeking to maintain air quality standards without sacrificing floor space. This unit integrates a robust 54-inch by 30-inch work surface with a powerful 1,750 CFM extraction system, effectively capturing welding fumes and grinding dust at the source. Designed for heavy industrial environments, the table supports a weight capacity of 440 lbs, making it suitable for a wide range of fabrication tasks.

Advanced Filtration and Mechanized Cleaning

At the core of the K2751-11 is its sophisticated filtration system. The unit comes equipped with two MERV 16 main filters, capable of capturing a minimum of 95% of airborne contaminants ranging from 0.3 to 1 micron in size. This level of filtration is critical for compliance with strict air quality regulations in manufacturing settings. A standout feature of this model is the mechanized cleaning system. By connecting an external compressed air source, the unit utilizes reverse pulses of air to dislodge particulate matter from the filter surface. This automatic maintenance feature prevents premature clogging, maintains consistent airflow, and significantly extends the operational life of the filters, thereby lowering the total cost of ownership.

Operational Versatility and Safety

The Prism Down Draft table is engineered for versatility, accommodating MIG, TIG, Stick, and Flux-Cored welding, as well as grinding and light-duty plasma cutting (up to 50 amps). The extraction dynamics are optimized with a split airflow design: 80% backdraft and 20% downdraft. This configuration ensures that fumes are pulled away from the operator's breathing zone regardless of the workpiece geometry. Safety is further enhanced by a three-stage spark arrestor system that captures hot particulates before they reach the filter chamber, mitigating fire risks. The unit operates on 208-460V three-phase power, integrating seamlessly into standard industrial electrical grids.

Ergonomics and Maintenance

Designed with the operator and maintenance team in mind, the K2751-11 features front-accessible controls and particulate collection drawers. The side panels can be unlocked and folded back to accommodate larger weldments that exceed the table's width. A color-coded filter status indicator provides immediate visual feedback on filter health, ensuring timely maintenance interventions. With a standard noise level of 78 dB(A), the unit operates within acceptable industrial noise limits, with optional silencer kits available for noise-sensitive environments.
