Nederman Extraction Arms are designed to capture airborne dust and fumes generated in industrial process such as welding, grinding and thermal cutting. Nederman Extraction Arms are highly flexible, simple to position, and easily extend and retract. Different attachments are available for wall, ceiling or extension bracket mounting as well as a number of accessories, including hoods and dampers to improve efficiency. The arms can be connected to a vacuum or filter system for removing contaminants from the extracted air so the air can be returned to the atmosphere or recycled without negative effects.
