What is a pneumatic system?

A pneumatic system is defined as a system that utilizes compressed air to transmit and control energy. In such systems, air is compressed and stored in a reservoir, and when needed, it is released to perform work. This can include moving pistons, operating tools, or controlling machinery, allowing for precise control and responsiveness in various applications.

Pneumatics are favored in specific environments due to their cleanliness, as they do not involve oils or other liquids that can leak and create hazards. Additionally, pneumatic systems generally operate at lower pressures compared to hydraulic systems, making them lighter and often easier to maintain.

The other options describe different types of systems that do not match the specific function of pneumatic systems. For example, systems that use hydraulic fluid transmute energy through liquids under pressure, while those that operate on electrical power rely on electronic circuits and devices. Systems using gravity for movement harness the natural force of gravity rather than compressing air for energy transmission.
