Hi everyone.....in my pneumatics class I need to write a one page report of a pneumatic system giving a complete description on the role of the hydraulic or pneumatic system including the control mechanisms and any advantages or disadvantages you see in the system when compared against some other system (say a mechanical system).

The W140 popped into my head with their pneumatic door assists but I cant seem to find any detailed info on the net.

Can anyone fill me in as much as they can?

Much Appreciated!
