1. Working fluid : Pneumatics use air, Hydraulics use Oil
2. Power : Pneumatic power less than hydraulic power
3. Size : P components are smaller than H components
4. 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 pump
6.Air is compressable, hydraulic oil isn't
Hydraulic oil is slightly compressable particularly when air is entrained within it
Hydraulics can also attain power from an air accumulator
PNEUMATIC POWER IS NOT BNECESSARILY LESS THAN HYDRAULIC POWER
THE LOSSES TEND TO BE GREATER IN PNEUMATICS BUT THIS IS DUE TO ENGINEERING RATHER THAN CHARACTERISTICS.
Pneumatics are much easier to configure for control applications
I disagree with answer 3 above, it depends on the application.XD

Pneumatic machines use the power of compressed air to perform work.
Hydraulic machines use the incompressibility of water under pressure to perform work.
What else can I help you with?
The main difference between pneumatic cylinders and hydraulic cylinders is that hydraulic cylinders?
Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
How the correlation between hydraulic motor and hydraulic pump?
Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.
How can you tell the difference between a hydraulic lifter and a mechanical lifter on a Chevy 350 engine?
Take a pushrod and push down on the plunger in the lifter. A hydraulic lifter is spring loaded.
Where is the throttle valve in a hydraulic system?
In a hydraulic system, the throttle valve is typically located in the hydraulic line, often between the pump and the actuator (such as a hydraulic cylinder or motor). It regulates the flow rate of the hydraulic fluid, controlling the speed and power of the actuators. By adjusting the throttle valve, operators can fine-tune the system's performance to meet specific operational needs.
What is the difference between a hydrostatic and a hydraulic system?
By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".

Difference between hydraulics and pneumatics?
hydraulic is liquid based, pneumatic is air.
What is the difference of pressure between pneumatic and hidraulic?
Any pressure difference is irrelevant. The distinction is in the operating fluid. In pneumatic systems, it's a gas. In hydraulic systems, it's a liquid.
What is the difference between pneumatic elevator and hydraulic elevator?
Pneumatic elevators work on air pressure (similar to a bank's drive through suction tubes) and hydraulic elevators work on oil/water pressure.
What is the Difference between pneumatic cylinders and hydraulic cylinders is?
Working fluid. In one it's gas (air) and in the other it's liquid. This is a much bigger difference than it might seem at first, because gases are compressible and liquids, to a very good approximation, are not.
What is the difference between hydraulic and pneumatic symbols?
It all comes under Fluid dynamics/mechanics, and it's the same set of symbols for circuits. Many hydraulic symbols will include a drain to the tank. Pneumatic circuits use the atmosphere as their "tank".
What's the difference in performance between a pneumatic and a hydraulic rotary actuator?
Hydrolic are faster and more powerful. They use comressed air.
What is the main difference between pneumatic cylinder and hydraulic cylinders?

How are pneumatic and hydraulic systems different?
the main difference between hydraulic and pneumatic system is that hydraulics uses fluid to power their system and pneumatic uses air (in that case air is not a fluid) All matter is made up with all particles. thanks you can see more answer in this web i put these all answer.
What is the difference between a valve and actuator?
actuator is a mechanism that will responds to hydraulic,pneumatic and electrical signal ,it is used to control the valve that to be in open or close condition.
Difference between Pneumatic and hydraulic test?
There are many differences, and here are a few: Pneumatic systems use gasses which are compressable - hydraulic uses liquids that are non-compressable. Hydraulics' motion is slow and smooth - pneumatics' motion is quick. Pressure can range from 500 to 5000 psi - pneumatics operate at around 100 psi.
What is the difference between single action actuating cylinder and double acting cylinder?
Single action actuating cylinder means that fail action (open or close) is accomplished by spring mounted on the opposite side of pneumatic cylinder and normal operation by airDouble acting cylinder means that both, opening and closing, manoeuvres are accomplished by pneumatic cylinder.
