The vacuum suction system with a capacity of 5,000 liters was designed for the suction and transportation of cement slurry from the tunnel
for the major project Stuttgart 21.
In order to prevent the emission of exhaust fumes, the electric motor with 63 A is integrated, which drives the compressor with a suction capacity of 9,500 l/min.
Equipped with a ballast system, the vacuum compressor is suitable for continuous operation at a vacuum of 0.6 bar.
