Pneumatic means pertaining to air. It is often used with reference to devices which work by using pressurised air as the motive force.
Simple electro-pneumatic devices include pneumatic cylinders that are controlled by solenoid valves, allowing for linear motion in automated systems. Another example is pneumatic grippers, which use compressed air to grasp and manipulate objects. Additionally, pressure regulators that adjust air pressure in a system based on electrical signals demonstrate electro-pneumatic functionality. These devices are commonly used in manufacturing and assembly processes for efficient automation.
Some actuator or devices are operated by compressed air. These devices are known as pneumatic components
Ball Valve
A current signal can be converted into a pneumatic signal using a current-to-pressure (I/P) transducer. The transducer converts the electrical current input into a corresponding pneumatic pressure output that can be used to operate pneumatic devices like cylinders and valves. This conversion allows for the control and automation of pneumatic systems using electrical signals.
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.
Pascal's principle states that a change in pressure applied to an enclosed fluid is transmitted uniformly in all directions. In pneumatic devices, such as pneumatic cylinders or air brakes, this principle is utilized to control the movement or operation of the device by applying pressure to the enclosed air, which then transmits force to the components of the device.
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.
