How does pressure differ between hydraulic and pneumatic systems?

Hydraulic systems are designed to work with fluids, typically oils, to transmit power. These systems are capable of generating and sustaining significantly higher pressures, often in the range of 1,500 to 3,000 psi or even higher depending on the application. The high pressure allows hydraulic systems to move heavy loads and perform tasks that require a substantial amount of force, making them ideal for heavy machinery and industrial applications.

In contrast, pneumatic systems use compressed air as the working fluid. While they can also produce force, the operating pressures for pneumatic systems are generally much lower, typically ranging from 80 to 120 psi for most applications. This difference in operational pressure limits the load-bearing capabilities of pneumatic systems compared to their hydraulic counterparts. Therefore, hydraulic systems indeed operate under higher pressures than pneumatic systems, enabling more powerful and precise actions in various applications.
