A pneumatic actuator is a device that is capable of converting energy from a pressurized gas into motion. There are several different types of pneumatic actuators and each of them are designed in a slightly different way. Pneumatic actuators can be used to produce both rotary and linear motion and are usually powered by an electric compressor. While motion can be created through other means, such as a hydraulic or electric motor, pneumatic actuators are safer, cheaper, more reliable, and often provide more power.
