Pneumatic actuators are capable of producing some of the highest closing forces of all actuator types. Some pneumatic actuators can have a maximum pressure rating of 250 psi and can generate forces of up to 40,000 lb. Relatively fast closing speeds of up to 2m/s are also possible with this type of actuator. Both the speed and the force of the actuator can be easily fine-tuned by adjusting a system of pressure relief valves or flow regulators.
Another key advantage of pneumatic actuators is the comparatively low per unit cost. Pneumatic cylinders are inexpensive and can be easily upgraded to larger diameters. Large air compressors are also very efficient and economical for powering large groups of pneumatic devices.
