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

The primary advantage of using pneumatic systems over hydraulic systems is that pneumatics are generally lighter and easier to maintain. Pneumatic systems utilize compressed air as the working fluid, which is typically less dense than hydraulic fluids, making the components lighter overall. This characteristic is particularly advantageous in applications where weight is a critical factor, such as in automation and robotics.

Additionally, maintenance tends to be simpler with pneumatic systems. The absence of oil or other hydraulic fluids means there is less risk of leakage and contamination, which can complicate maintenance tasks in hydraulic systems. Pneumatic components often have fewer mechanical parts than hydraulic ones, and the use of air not only reduces resource costs but also generally results in longer intervals between maintenance checks.

Overall, these factors contribute to the appeal of pneumatic systems in various applications, highlighting their efficiency and practicality compared to hydraulic systems.
