What is one advantage of using pneumatics over hydraulics?

Using pneumatics has the distinct advantage of lighter components, primarily because the materials involved in pneumatic systems are generally less dense compared to those used in hydraulic systems. Pneumatic systems typically utilize air or gas, which requires less robust structural elements for the same operational requirements. This reduction in weight can lead to easier handling, installation, and maintenance of pneumatic equipment.

In contrast, hydraulic systems involve liquids, which necessitate components made from heavier and more durable materials to contain high pressures. Therefore, while the other aspects like energy efficiency, operational noise, and design complexity are noteworthy, the advantage of lighter components is a significant factor when choosing pneumatics for applications where weight savings and ease of movement are critical considerations.
