The principles of pneumatics are the same as the principles for hydraulics, Only difference between them is that pneumatics use gas instead of a liquid to transmit power. Generally in pneumatics compressed air is used for transmitting power. For special applications some inert gases & nitrogen can be used.
With pneumatics products like, the air is transferred into receiving cylinder with the help of a compressor. The receiver will then hold high quantity of compressed air & then it can be used by pneumatic systems when needed.
In case of Hydraulic systems, they uses oil that rotates around the system. Unlike in Pneumatic systems, the oil isn't changed but the same liquid is used throughout the process. some examples of hydraulics system are Dentist chairs, power steering, brakes of vehicles.
