The LE-LS-LC mini sanders and the GREENTECH filter have been awarded the TNO certification for maximum safety and minimum dust dispersion for up to 8 hours use.

The LE-LS-LC mini sanders series, and the GREENTECH filter unit developed by RUPES, have been awarded the prestigious TNO certification, which certifies that the tools create the minimum dust dispersion during sanding up to eight hours. The certification had already been awarded for a limit of up to 2 hours of use, and has now been extended to 8 hours. This is thanks to improvements in the RUPES products, which have increased the level of safety and environmental respect.

The TNO (Netherlands Organization for Applied Scientific Research) is a leading independent scientific Institute, specialized in the study of tools, processes and design of the working environment in the industrial sector. The main objective of these studies is to create production processes with low environmental impact and low dust generation. TNO performance tests are mandatory in the Netherlands, and are conducted on the entire sanding system including both the tool and filter. These tests certify that levels of hazardous substances such as crystalline silica, dust and wood residues or hexavalent chromium, dispersed in the environment during use, do not exceed the maximum permitted limits.
