Central medium vacuum systems consist of an extraction plant connected to a network of spiral-seam tubing. Hoods, extraction arms and other extraction devices can be connected at the workstations.
Extractors are usually rated between 7.5 and 30 kW. The total tube length ranges from 50 to 200 metres. Central medium vacuum systems ensure clean air on factory shopfloors and in large workshops.
Applications of the central medium vacuum system include:

• Central welding fume extraction
• Soldering fume extraction
• Extraction of adhesive vapours
• Zinc vapour extraction in flame spraying
