What is the primary function of a pneumatic actuator?

The primary function of a pneumatic actuator is to convert compressed air energy into mechanical motion. Pneumatic actuators operate based on the principle of using compressed air to create force, which then drives a mechanical component, such as a piston or diaphragm, to perform a specific movement. This capability allows pneumatic actuators to be effectively utilized in various applications, including automation, robotics, and industrial machinery, where rapid and robust motion is necessary.

Pneumatic actuators are especially valued for their speed, simplicity, and reliability. By utilizing compressed air, they can provide high power-to-weight ratios, making them suitable for tasks that require quick and efficient movement without the complexities associated with electric or hydraulic systems.
