Pneumatics is a term that is used to describe anything that uses compressed air in order to perform. Inert gases are compressed and stored in containers. A line is then attached to the container, which allows the air to be released. This line can be hooked up to a variety of different things, including machines and tools, in order to operate the tools. This compressed air adds pressure and strength to the tools being used with little effort from the person using them when dealing with pneumatic systems.
