Metal fabrication is one of Mimault’s core businesses. This French company has a couple of welding workshops in its production facility. Most of the welders work with small metal workpieces. To use the floor space of the entire workshop optimally, all workplaces are relatively small as well. This means that many welders can work simultaneously on site.
One of the consequences was that all welding fumes accumulated into the workshop and generated a ‘blue layer’ inside the building, just below the roof. In order to remove this vast amount of welding fumes the employees opened all doors to create natural ventilation. Nevertheless, it was obvious that the open doors did not create enough general ventilation to remove all welding fumes. Mimault needed a professional extraction and filtration system to create a clean, safe and healthy working environment for its employees.
