Q
Advantages of pneumatics
A
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.
5
Q
Disadvantages of pneumatics.
A
Pneumatic components produce relatively small forces.
It is not very energy efficient compared to electrical systems.
