An air brake uses a diaphragm connected to an operating rod to work the brake. Behind the diaphragm there is a spring which applies the breaking force at all times. To release the break either pressure is applied to the other side of the diaphragm or a vacuum is applied to the spring side. Because the diaphragm has a large surface area just a few p.s.i. can produce a large force. E.g. A 8 inch diameter unit would produce over 700 lbs thrust at 14psi this force is often further amplified by the leverage of the linkage. This arrangement makes the brake fail to the safe "on" state.
Central pneumatic is a company and they sell tools of the power sorts, including: air compressors and air hoses. The products they sell are mainly bought by machinists and shops for use in industry.

A variety of automation systems use pneumatic tubes to move material via puffs of air. Bank systems still use them. In the Denver Airport, large pneumatic tubes move aircraft parts around the terminals.
1. Working fluid : Pneumatics use air, Hydraulics use Oil2. Power : Pneumatic power less than hydraulic power3. Size : P components are smaller than H components4. Leakage : Leaks in hydraulics cause fluid to be sticking around the components. In pneumatics air is leaked into the atmosphere.5. Pneuatics obtain power from an air compressor while hydraulics require a pump6.Air is compressable, hydraulic oil isn'tHydraulic oil is slightly compressable particularly when air is entrained within itHydraulics can also attain power from an air accumulatorPNEUMATIC POWER IS NOT BNECESSARILY LESS THAN HYDRAULIC POWERTHE LOSSES TEND TO BE GREATER IN PNEUMATICS BUT THIS IS DUE TO ENGINEERING RATHER THAN CHARACTERISTICS.Pneumatics are much easier to configure for control applicationsI disagree with answer 3 above, it depends on the application.XDMiss.godgivenhope@hotmail.comPneumatic machines use the power of compressed air to perform work.Hydraulic machines use the incompressibility of water under pressure to perform work.
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.
Air. Pneumatic systems use compressed air.
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.

when high power transmission is involved then hydraulics is the best option this because there are hydraulic fluid available to suit the various pressure levels. liquids have almost zero compressibility. in pneumatic system air is the working fluid, too high pressure could compress the air to such an extent to liquify it causing the tubes to crystallize and burst it. air is highly compressible and hence power loss should also be accounted for the compressed air so only low power systems possible here eg: pneumatic door openers .
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
pneumatic system use air and air has its limitation of use mainly due to its high compressibility as gas.high power applications may compress air to such an extent leading to destruction of the system.whereas hydraulics also have compressibility which is at an unnoticed level even at high pressure. I meant motors or generators that run on air released from a reservoir of compressed air.
