Ventilation method: Suction duct system [Patent No. 3883483]
It is the optimal ventilation method that meets the guidelines as a measure against dust generation sources.
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.*
basic information
【Features】 ■ The self-propelled telescopic duct moves along the rail and sucks up dust right before the face. ■ As it addresses the source of dust, it is the optimal ventilation method that meets guidelines. ■ It can be extended and contracted according to the excavation method and work cycle, so it does not cause any hassle. ■ By ensuring the minimum airflow to the face and a high clean space at the rear, it significantly reduces ventilation and running costs. ■ Both the duct and the hanging rail can be easily advanced with a wireless remote control. 【Specifications】 ■ We have a variety of lineups available.
