What is the primary advantage of using pneumatic systems over hydraulic systems?

The primary advantage of using pneumatic systems over hydraulic systems is the lighter weight. Pneumatic systems utilize compressed air as their operating medium, which can often be lighter than hydraulic fluids. This characteristic makes pneumatic systems more suitable for applications where weight is a critical factor, such as in aerospace or portable tools. The use of air, which is much less dense than hydraulic fluids, contributes to the overall reduction in the weight of the system.

Additionally, the components used in pneumatic systems, like air cylinders and hoses, tend to be lighter compared to their hydraulic counterparts, which involve pumps, tanks, and fluid reservoirs filled with oil or other hydraulic fluids. This aspect of weight efficiency allows for greater flexibility in design and easier handling, especially in mobile or compact applications.

Higher force output, less maintenance, and less energy consumption are benefits that might be associated with hydraulic systems rather than pneumatic ones, as hydraulic systems are known for their capability to produce higher force due to the incompressibility of liquids, and they generally require specialized maintenance related to fluid leaks. Energy consumption can vary widely based on the specific application and how the systems are configured.
