Extraction systems are used in areas where production processes release dust or gasses that are a health or environmental hazard. They are a standard component for metal grinding machines, woodworking machines, plastic or chemical production and exhausts for combustion engines. During all types of thermal cutting or the combining of metals, for example, the soldering or plasma cutting of metals, gaseous emissions are an extreme health hazard. Therefore, it is particularly important that there is a continual extraction system in place. This is also the case for all types of metal coating, especially galvanised steel.
