Suction excavator has collection container, turbine generating suction flow, controller with closure device downstream of filter devices in flow channel for varying flow channel cross-section

摘要

The device has a collection container (14) in which a suction flow is generated by a turbine (28) to suck in material that is separated from the air flow into the container, filter devices (16) after the container and a controller. The controller has a closure device (22) downstream of the filter devices in the flow channel (25b) for varying the flow channel cross-section.
