Mobile welding fume extractors filter air to remove and filter harmful gasses, vapors, and fine particulates to provide clean breathing air and remove combustible contaminants. These wheeled fume extractors are rolled around a shop to set up near the workpiece and are suitable for TIG, MIG, stick, and autogenous welding applications. Removing contaminants helps meet OSHA requirements and prevents buildup of potentially combustible gasses and harmful toxins that can affect worker health. Clean, filtered air is returned to the same workspace, eliminating the need for external venting.
