Pneumatic device: Pneumatic device, any of various tools and instruments that generate and utilize compressed air. Examples include rock drills, pavement breakers, riveters, forging presses, paint sprayers, blast cleaners, and atomizers. Compressed-air power is flexible, economic, and safe. An air device creates no spark hazard in an explosive atmosphere and can be used under wet conditions without electric-shock hazard. A relatively small compressor suffices to fill a storage tank for intermittent use, and no return lines are needed.
