Norra länken, Stockholm

Our impulse fans keep the North link ventilated.

Norra länken is a road tunnel in Stockholm that opened to traffic in 2014, and is equipped with impulse fans suspended from the ceiling.
For this tunnel, we have delivered 158 impulse fans which are responsible for tunnel ventilation.

The fans are of different designs and sizes, e.g. diameters of 1000 mm and 1250 mm. There are also both unidirectional and reversible fans.

The fans are manufactured by our partner Witt&Sohn from Germany.
