| | | The driving source is a compressor manufacturer that is placed close to the system in some suitable space. A simple pipe system is run from the compressor to the actual printing room. There, where they are of optimum use, both the PVBS (PIAB Vacuum & Blow System) and the small, efficient pumps are placed. These can be blow pumps that transfer and condition the paper at the feeder. They can also be blow pumps that facilitate the paper transfer between the printing units, and they can very well be vacuum | | pumps that are used to work as paper brakes at the delivery. They can also be vacuum- and blow pumps that are used to correctly handle the paper in, for example, the stitching, and binding, cutting and packaging processes. Each pump operates only when being used, while all other pumps remain at standstill, thus saving energy. | | |
