During sweeping, the blower generates the vacuum
in the hopper and the air pressure for cleaning and
drying the road surface.
The high-power blower is fastened to the base
frame with rubber mounts. It is hydraulically driven.
The power of the blower is set with the rpm of the
diesel engine. On the outlet side, the discharged air
can be routed upwards or sent to the blast nozzles.
Interchangeable rubber strips are used as gaskets
around the vacuum and the suction air outlet
frames.
There is a cleaning aperture on the top of the
housing (1).
