Why fume extraction at the torch?
“The first reason is always the protection of the people, even when they are not welding”, says Juliane Osmont, Export Manager at Engmar. Their compact ATMOFLOW vacuum unit offers impressive precision, filtering up to 98% of harmful particles during welding. “Torch extraction is the most effective way of extracting welding fumes because it extracts directly at the welding zone”, states Osmont. This means that the fumes do not have time to mix with the surrounding clean air, so only a small volume of air is needed for extraction. In the cold winter months, this has another advantage: “Because the volume of extracted air is so small, companies do not lose much heated air when extracting outside.”
