Enclosed Robotic Welding Cell Fume Extraction System - LEFILTER Solution

Product Introduction:

LEFILTER's solution for robotic welding automation consists of custom-engineered enclosures with integrated fume extraction. The enclosure, built from industrial-grade panels with clear viewing windows, physically contains the welding arc and fumes. The extraction system is a high-vacuum, low-volume (HVLV) design featuring a centrifugal fan specifically selected for the high static pressure needed to pull fumes through capture arms or slotted hoods. The filtration unit uses long-life, fire-retardant cartridge filters with nanofiber media for exceptional capture of sub-micron metallic oxides (e.g., hexavalent chromium, manganese, zinc). The system is fully automated, synchronizing with the robot's welding cycle.

Application Area:

This system is designed for high-production robotic MIG/MAG or resistance welding cells in automotive, machinery, and metal fabrication. Robotic welding generates a concentrated, continuous plume of toxic fumes at a fixed point. Without proper containment, these fumes quickly fill the shop, exposing other workers and contaminating the general ventilation system. The fumes pose serious long-term health risks (cancer, neurological damage) and can settle on sensitive automated equipment, causing premature failure.

Our Solution:

LEFILTER partners with automation integrators to deliver a turnkey containment solution. We design the extraction points—often overhead slotted hoods or dedicated fume arms—to be precisely positioned near the weld torch without interfering with the robot's path. The HVLV system ensures fumes are captured at the arc with minimal air volume, saving energy on heating or cooling make-up air. The clean, filtered air can often be recirculated inside the factory, saving on energy costs. Our solution provides a cleaner overall factory environment, protects the health of all personnel, maintains the reliability of surrounding robotics and controls, and ensures compliance with stringent indoor air quality regulations like OSHA PELs.
