Printing and paper production rely on compressed air for fast, precise material handling and control. Sheet and web handling, tension control, coating, cutting and packaging all use air, and contamination in the line can ruin an entire run.
Key applications
- Sheet feeders and air tables for paper transport
- Web tension and edge-guide control
- Coating, drying and anti-set-off spray systems
- Guillotine and folder actuation
- Dust blow-off and cleaning
Air quality
Air that contacts paper or print must be oil-free and dry. Moisture causes paper curl and ink problems, while oil produces stains. Instrument air for control systems needs a low dew point for stable operation of valves and cylinders.
System design
Demand in printing and paper plants is steady but includes sharp peaks from sheet feeders and air tables. Variable speed compressors with receiver capacity hold pressure steady, and point-of-use filtration protects the most sensitive coating and control stations.
