In pneumatic systems, what is the primary source of power?

In pneumatic systems, the primary source of power is air. Pneumatic systems operate by using compressed air to transmit energy and perform work. The pressurized air serves as a medium to power various tools and machinery, enabling movement and force.

The use of air in pneumatic systems is advantageous because it is readily available, can be compressed, and allows for rapid force application. Additionally, air is non-toxic and can be used in a variety of environments without the risks associated with hydraulic fluids or other liquids. This makes air an efficient and practical choice for many applications.

While options like electric power, nitrogen gas, and steam are sources of energy for different types of systems—such as electric motors in electric systems or steam in hydraulic and thermal systems—they do not serve as the primary medium for pneumatic power. Therefore, it is air that stands out as the foundational element in the operation of pneumatic systems.
