Due to the special properties of paper, vacuum and compressed air are essential features in paper manufacturing and processing.
Vacuum is required for a variety of applications in the pre-press area, including preparing images and film for scanning or exposure and for copying printing plates. There are also many applications where over-pressure is needed as well, such as for guiding plates or film in automatic systems.
In classic sheet fed offset presses, vacuum and overpressure is always needed for paper handling – at the feeder to separate the sheets, to feed the single sheets to the different colour-aggregates or to guide the sheets through the machine. All these applications need different amounts of air at different pressures.

There are a variety of applications in the post-press arena. For example, side-channel blowers for folding and cutting machines; pressure-vacuum pumps and individual vacuum pumps and compressors for collating and book-binding machines; and radial blowers for removing waste paper.

Customer-specific adaptation of air demand in the printing and paper industry is best achieved by using the modular Elmo Rietschle Air-Center. They assure a higher operating safety through extremely low noise levels and lower temperature. The air consumption can be adapted to individual print jobs, which means a considerable reduction in set-up costs and energy consumption.
