What generally distinguishes pneumatic systems from hydraulic systems?

The distinguishing factor for pneumatic systems is that they utilize compressible fluids, typically air or gas, while hydraulic systems operate using incompressible fluids, such as oil or other liquids. In pneumatic systems, the compressibility of the gas allows for rapid movement and flexibility in applications where lighter weight and lower viscosity are advantageous. This characteristic also influences the design and functionality of pneumatic equipment, leading to different applications compared to hydraulic systems.

Understanding this distinction is crucial, as it affects factors such as system pressure, response time, and the types of tools or machinery that can be effectively powered by each system. Pneumatics, utilizing gas, are more responsive in certain scenarios but may not generate the same level of force as hydraulic systems, which are better suited for heavy-duty applications due to their use of liquids.
