In the presence of fumes or dust-laden air, extraction arms are a good complement for extraction systems. They apply suction directly at the source of dust or smoke without hindering the workflow.
With a single handle, the extraction arm can be accurately moved to the desired suction position within seconds. Supporting rods and joints are deliberately mounted on the exterior to remain clean without impeding the air flow. Keller offers a variety of designs from standard extraction arms, to ATEX compliant versions, to special extraction arms for the pharmaceutical, food, and chemical industries.
