What is a common characteristic of pneumatic systems compared to hydraulic systems?

Pneumatic systems are characterized by their use of compressed gas, typically air, to operate machinery and perform tasks, whereas hydraulic systems use liquid (usually oil) to transmit power. This fundamental difference in the medium used to generate and transmit force gives pneumatic systems unique properties, such as lighter weight and faster response times than hydraulic systems.

In addition, using gas allows for less risk of leaks and contamination, which can be critical in certain applications. Understanding this distinction helps in choosing the right system for specific tasks, as pneumatic systems are preferred in applications where speed and cleanliness are priorities, while hydraulic systems are chosen for their power and control in heavier applications.
