As a measure to address dust generation sources, it is the optimal ventilation method that meets the guidelines.
The self-propelled telescopic duct moves along the rail and sucks up dust just before the face. Compared to conventional methods, it cleans the entire tunnel with a lower air volume (only in the case of a combination with a filter-type dust collector). This method is also recommended by the International Tunneling Association (ITA). *For more details, please feel free to contact us.*
