Pneumatic means pertaining to air. It is often used with reference to devices which work by using pressurised air as the motive force.
Some actuator or devices are operated by compressed air. These devices are known as pneumatic components
Ball Valve
Usually ordinary air is used in a pneumatic system.
Companies in the fluid power cylinders and actuators industry manufacture hydraulic and pneumatic cylinders used in various devices, such as jacks, lifters, and machine tools.

Sand blasting uses air pressure as an ejector within the blasting process. This is how the pneumatic system is used in a pneumatic sand or paint blaster.
Pneumatics is the use of pressurized air to effect mechanical motion. Pneumatics is used in a variety of different areas.For example in dentistry applications, pneumatic drills are lighter, faster, and simpler than an electric drill of the same power rating (because the prime component, the compressor, is separate from the drill and pumped air is capable of rotating the drill bit at extremely high rpm). Pneumatic transfer systems are employed in many industries to move powders and devices. Pneumatic tubes can carry objects over distances. Pneumatic devices are also used where electric motors cannot be used for safety reasons, such as deep in a mine where explosive dust or gases may be present.
Some hospitals use a pneumatic tube system.
FRL is Filter, Regulator, lubricator Filter filters the air from minute dirt and moisture particle from entering the pneumatic devices. Pneumatic devices work well if the air is dry and dirt free. In some applications where air directly in contact with the product being produced, like food products, air quality has to be food grade free from dirt and moisture. Regulator is needed to regulate the pressure setting as required. Lubricator is used where pneumatic cylinders are used, for smooth functioning of the cylinders. If no FRL, the pneumatic device ultimately becomes less efficient and/or stops functioning properly.
Air pressure is used as ejector for the sand blasting.
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
