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.
