FILTRONtec is one of the world’s leading companies specialised in the filtration of contaminated air in road tunnels.
FILTRONtec’s highly efficient filtration technology makes a sustainable contribution to the improvement of air quality by a successful reduction of pollutant emissions at tunnel portals or within the tunnel. FILTRONtec filtration technology is characterised by a high separation rate of the especially harmful fine particles. In addition, the concentrations of nitrogen oxides and other noxious tunnel gases are able to be reduced by a simple filtration process if required. Air filtration plants lead to a technology change for the ventilation systems in road tunnels with environmental and economical benefits. This allows a decrease in the road tunnel construction time and cost, and through life operational and maintenance costs.
FILTRONtec has a network of subsidiary companies and partners to design and build air filtration plants for road tunnels worldwide and engages in an active continuous development program of the core technologies.
