What are fume extraction arms used for?

Fume arms are primarily used for capturing and removing airborne contaminants directly at their source, thereby protecting workers from inhaling hazardous substances and improving overall air quality in the work environment. These devices are widely used for manual welding and other applications where toxic fumes, dust, or particulate matter are generated. They are generally best for environments with light to moderate manual production processes. In addition to welding and metalworking, they may be used for bench-scale laboratory applications, control of moisture and odors in food manufacturing, and control of toxic dust.
