Efficient. Modular. Sustainable.<\/h2>\n\n\n\n

FILTRONtec stands for modern air filter systems that effectively remove fine dust and nitrogen dioxide from the tunnel air - for better air and more safety.<\/p>\n\n\n\n

Our systems are specially developed for the demanding conditions in tunnels and make a decisive contribution to a clean and safe tunnel atmosphere. At the same time, they protect local residents and ensure improved air quality at the tunnel portals and air outlets.<\/p>\n<\/div>\n<\/div>\n\n\n\n
