Many production processes and treatment methods generate aerosols, dust, smoke, gases or chips, which must be extracted. A good example of companies that work with media that are hazardous to health are paint shops where powerful, reliable and resistant extraction systems are essential. However, harmful or hazardous substances are produced, which must be sucked in as close as possible to the source of emissions and passed on in a controlled manner, are also produced in other industries and working areas, such as welding, soldering, sawing, milling, flexing and decanting of materials and liquids. Depending on the operation and requirements, various fans are used to suck in the contaminated exhaust air and transport it – if necessary after passing through appropriate filters or separators in the extraction system – back into the room in a processed state or outside into the open air.
