Advantages of pneumatics
Pneumatic systems are very reliable because the equipment lasts for a very long time.
Pneumatic systems are cheap to run because they last for a long time, and they use compressed air.
Pneumatic systems are easy to install and do not need to be insulated or protected like electronic systems.
Disadvantages of pneumatics.
Pneumatic components produce relatively small forces.
It is not very energy efficient compared to electrical systems.
