Pneumatic systems are defined by their use of compressed air to generate force and perform work. This characteristic distinguishes them from other systems, such as hydraulic systems, which utilize liquids to transmit force. Pneumatic systems leverage the mechanical properties of compressed air to operate tools, actuators, and other equipment. Compressed air is readily available and can be easily generated using compressors, making pneumatic systems versatile and widely used in various industrial applications.

The nature of pneumatic systems means they do not rely on hydraulic fluids, which rules out any options suggesting a hydraulic function. Additionally, pneumatic systems do not consistently require a constant electrical input; instead, they primarily depend on air pressure variables for operation. While discussions of efficiency can arise when comparing pneumatic systems to electrical ones, this is a broader topic that doesn't directly define the core characteristic of how pneumatic systems function. Thus, the use of compressed air is the defining quality that best describes pneumatic systems.
