The machine – How it works

The fan generates an air current of up to 44,000m³/h and a maximum vacuum of 55,000 Pa. The suction hose is moved three-dimensionally via a hydraulically operated boom. The air current removes all material through the suction crown. All materials can be sucked up, solid materials up to 250 mm in diameter. The air is quitened and deflected in the collection chamber so that the main elements of the intake are eliminated. Separation chambers provide further purifying and drying of the air stream. The collection tank is positioned such that the load is optimally distributed over the vehicle axles. The superfine filter unit separates the finest dusts from the air flow. The purified air is discharged to the top via a sound absorbing unit. The fine-mesh filters are cleaned with compressed air. The collection chamber, the separation chambers and the fine-mesh filter unit are emptied whenever a tilting operation is performed. All functions of the superstructure are controlled via a radio-operated remote control box or via a cabled remote controller. 

The internationally patented RSP suction principle guarantees the highest degree of gravity separation, lowest load on the filters, and consistently high suction performance.
