K2751-16 - Lincoln DownFlex 400-MS/A 575V Automatic Cleaning Downdraft Table

Technical Overview of the Lincoln DownFlex 400-MS/A

The Lincoln Electric DownFlex 400-MS/A (SKU: K2751-16) is a high-efficiency downdraft table designed for industrial environments requiring 575V input power. This unit functions as both a robust workbench and a localized fume extraction system, engineered to capture particulate, dust, and welding fumes at the source. The 'MS/A' designation indicates this model features a Mechanized/Automatic cleaning system, which utilizes compressed air pulses to dislodge accumulated particulate from the filter media, depositing it into collection drawers. This self-cleaning capability is critical for high-production environments, ensuring consistent airflow and prolonging filter service life.

The extraction dynamics are calibrated for maximum capture efficiency, utilizing a split airflow design that provides 80% backdraft and 20% downdraft velocity. This configuration is particularly effective for welding and grinding operations where fumes naturally rise or are projected backward. The unit is also rated for light-duty plasma arc cutting applications up to 50 amps. Safety is paramount in the design, featuring a built-in three-stage spark arrestor system that prevents hot sparks from reaching the filter chamber, thereby mitigating fire risks associated with grinding and welding.

Maintenance accessibility is streamlined with front-facing access to all critical components, including controls, filter cartridges, and dust collection drawers. The unit operates at a standard noise level of 78 dB(A), with options available to reduce this further. The K2751-16 is a comprehensive solution for facilities seeking to comply with air quality standards while optimizing floor space by combining the work surface and extractor into a single footprint.
