What is a notable advantage of pneumatics compared to hydraulics?

Pneumatics offer a notable advantage in that they are generally cleaner and easier to maintain compared to hydraulics. This is primarily because pneumatic systems utilize compressed air or gas, which does not present issues associated with leaks that can arise in hydraulic systems that use oils or fluids. The absence of oil in pneumatic systems minimizes the risk of contamination and environmental concerns, making them more suitable for use in applications where cleanliness is crucial, such as in the food or pharmaceutical industries.

Additionally, maintaining pneumatic systems is often simpler since they have fewer moving parts and do not require the same level of fluid management, cooling, or filtration as hydraulic systems. This reduction in complexity can lead to lower maintenance costs and easier troubleshooting.

In contrast, the other options describe characteristics that are generally less advantageous for pneumatics. Operating costs can vary widely depending on the application, and while pneumatics can be affordable, they are not universally cheaper than hydraulics. Pneumatics do not achieve higher power density compared to hydraulic systems, which tend to deliver greater force in smaller packages due to their use of incompressible fluids. Lastly, while pneumatic systems may operate efficiently under various conditions, they often are not designed for high-temperature applications like hydraulic systems, which can handle a broader temperature
