Lorenzo Valerio owns a painting factory in Mariano Comense (CO), where he treats both wood and metal, and the difficult relationship with dust and waste is a constant in his business. For years, the operators in his plant have been working with orbital machines connected to wheeled vacuum cleaners.
Firstly, the dust and waste was never really removed and the staff went home extremely dirty. Maintenance had also become untenable because it was very invasive and not always effective.
In winter, the additional vacuum system in the sanding cabin sucks in thousands of cubic metres of warm air, which increases energy consumption for heating.
Finally, the orbital machines connected to the wheeled vacuum cleaners emitted a very high-pitched and annoying whistle when they were being used, which caused hearing problems.
