Nice presentation of our suction excavator / saugbagger , the EXVAC, by Mercedes-Benz Trucks. 
“The turbine sucks in over 30,000 cubic meters of air per hour. That’s the volume of ten Olympic-sized swimming pools.”
“It would swallow whole cut stones. And if necessary, over a distance of more than 100 meters. ”
“With this machine, we save at least one and a half days of work per week!”
Thanks to our German partner, R-Kraft !
