A fume arm, also known as an extraction arm, is a specialized ventilation device designed to remove airborne contaminants, such as fumes, dust, and particulate matter, directly from the source of emission. This is particularly useful in industrial settings like welding, where toxic fumes can pose a health risk to workers. The fume arm typically consists of a close-capture hood or nozzle, which is placed near the source of the fumes, and a duct system that transports the captured fumes to a filtration or exhaust system for treatment or removal.
