Machines of all types need power. Power allows the machines to do specific kinds of work. Two of the most efficient and compact forms of power for machines are hydraulic and pneumatic systems. Hydraulics and pneumatics can be configured into different types of power sources to lift, lower, pull, push, turn, rotate and move machines carrying tremendous loads. Tools can also be powered to break stone, join steel and cut wood. Hydraulics and pneumatics provide the energy to make work happen.
My thoughts go like this...(from watching 'Scrapheap Challenge"0 plus a little basic knowledge of physics. 1/ Pneumatics involve the movement of pistons and what not via the medium of compressed air or air under pressure. 2/ Hydraulics involve the movement of pistons and what not via the medium of compressed fluids or fluid under pressure. 3/ Fluid is denser than gas (compressed air). I believe hydraulics can handle far heavier loads than pneumatics. Pneumatics would appear to use a lighter more flexible medium than hydraulics. In answer to your question, I believe hydraulics would be far more effective at manipulating heavy loads versus pneumatics. However, pneumatics would be a more flexible system than hydraulics. Hows that?
Hydraulics is the use of liquids to transmit power. Pneumatics is the use of gases (usually air) to transmit power.
One similarity is that they both use fluids. Both gasses and liquids are fluids. the two are also compressible.
pneumatics are used only in low power applications hydraulics are used in medium to high power applications.
it is because pneumatics is more flexible and easy to use rather than hydraulic[ebolton] There is no need to have a reservoir or return piping. The working "fluid", air, is non-toxic and non-flammable. Poster below is correct. Air systems typically have a tank that is the analog of a hydraulic reservoir.[ebolton]*****************Actually there is need for air reservoir in industrial pneumatics systems.Hydraulics can handle more powerful aplications than pneumatics for the same overall dimensions, or can be more compact for the same power.
oil is slightly compressible 0.5 % at 70 bar. but air is compressible. so to get the required pressure pneumatics require more energy source than hydraulics also there are some limitations for pneumatics in terms of force.

In hydraulics. Power is transmitted through the air. The pneumatic. Power is transferred by the oil.
Hydraulics is the use of liquids to transmit power. Pneumatics is the use of gases (usually air) to transmit power.
BMW uses hydraulics for its brakes
Hydraulics use liquids as the working fluid, pneumatics use gases as the working fluid.
One uses a liquid, one uses air. not the same
Basically pneumatics deal with lower loadings, hydraulics offer a better power to space ratio, useful in say aircraft design.
It is extremely essential in Hydraulics and mechanics. Your car would not run without pneumatics.
Fluids are used in Hydraulics - fluids are essentially incompressible - they transmit forces well (e.g. a car bottle lack) Gases are used in pneumatics - gases are compressible - you can therefore store energy in a pneumatic system (e.g. a car tyre)
Solids do not flow at room temperature, so they are not practical for use in hydraulics. When a gas like air is used in a system similar to hydraulics, it is called pneumatics. Sometimes hydraulic systems use both, like in an automobile lift.
