What is a key characteristic of pneumatic systems?

A key characteristic of pneumatic systems is their use of compressed air for power transmission. Pneumatic systems operate by utilizing compressed air, which is generated by a compressor and stored in tanks, to perform work. This characteristic allows these systems to be lightweight and flexible, making them suitable for various applications such as material handling, automation, and industrial machinery.

The reliance on compressed air not only enables effective power transmission but also offers benefits like increased safety and reduced fire hazards compared to systems that depend on electrical circuits. Additionally, this feature allows for the easy control and modulation of force and speed, which is advantageous in many operational environments.

By focusing on the unique aspects of pneumatic systems, it is evident that their defining characteristic is the utilization of compressed air, which differentiates them from other types of power transmission systems like hydraulic or electrical systems.
