    All vacuum conveyors have a 5 year warranty.

    Vacuum is created with compressed air through COAX® technology or mechanical pumps (not shown in picture) (1). The bottom valve (2) closes and the vacuum increases in the container (3) and the conveying line (4). The product is carried away from the feed station (5) into the conveying line and then to the container. The filter (6) protects the pump and the surrounding area from dust and small particles. During the conveying time, the air shock tank (7) is filled with compressed air. At a preset or automatic time, the pump and the conveying are stopped and the bottom valve (2) is opened. The product is discharged at the same time as the air shock is activated and the compressed air cleans the filter from dust and small particles. When the pump starts again, this process is repeated and a new cycle starts. The suction time and emptying times are normally controlled by a pneumatic, an electric control system or completely automated with the new smart systems.
