The principles of pneumatics are the same as those for hydraulics, but pneumatics transmits power using a gas instead of a liquid. Compressed air is usually used, but nitrogen or other inert gases can be used for special applications. With pneumatics, air is usually pumped into a receiver using a compressor.
Why is fluid power used?
In these cases, fluid power – whether hydraulic or pneumatics – is used because it can deliver linear and rotary motion with high force and torque within a smaller, lighter package than is possible with other forms of power transmission. A cement mixer, for example, illustrates how different methods of power transmission may be used.
What is fluid power?
Fluid power is a term describing hydraulics and pneumatics technologies. Both technologies use a fluid (liquid or gas) to transmit power from one location to another. With hydraulics the fluid is a liquid (usually oil but can be water) whereas pneumatics uses a gas (usually compressed air).
Why are pneumatics better than hydraulics?

Why is filtration important?
Filtration is essential to prevent damage from solid particles like dust and dirt. Solid particles traveling through a system can score and abrade surfaces, enlarge critical clearances, promote internal leakage and, in hydraulics, even act as a catalyst to chemically break down the fluid. Particulates come from several sources, including built-in debris left over after manufacturing components; by-products of normal internal wear and tear during operation; and dirt ingested from the outside environment. Filters trap such contaminants, but the necessary level of filtration varies with the application and system.
Why are filters installed in pneumatic systems?
In pneumatic systems, a number of filters are usually mounted throughout a circuit to protect individual machines and processes. They’re often installed in conjunction with regulators and sometimes lubricators, comprising an FRL. Keep in mind that contamination that is damaging in one system may be harmless in another.
Does running a system cleaner than necessary hurt the system?
Running systems cleaner than necessary does no harm to a system, but it wastes money. Also specify the right filter size. Select a filter for minimal pressure drop at the highest flow. Most manufacturers supply pressure and flow curves to rate pressure drop and dirt-holding capacity.
Is water a contaminant in a fluid power system?
Dry systems work best. Water is also a damaging contaminant in fluid power systems. Water vapor in the air is routinely drawn into compressors that raise the air’s pressure, temperature and dew point increase. Any subsequent cooling downstream can cause the water vapor to condense and liquefy.
