Editing Compressor (section)

==Applications==
Gas compressors are used in various applications where either higher pressures or lower volumes of gas are needed:
* In [[pipeline transport]] of purified natural gas from the production site to the consumer, a compressor is driven by a motor fueled by gas bled from the pipeline. Thus, no external power source is necessary.
* In maritime cargo transport and cargo operations by [[gas carrier]]s.
* Petroleum refineries, natural gas processing plants, petrochemical and chemical plants, and similar large industrial plants require compressing for intermediate and end-product gases.
* [[Refrigeration]] and [[air conditioner]] equipment use compressors to move [[heat]] in [[refrigerant]] cycles (see ''[[vapor-compression refrigeration]]'').
* Gas turbine systems compress the intake [[combustion]] air.
* Small-volume purified or manufactured gases require compression to fill high pressure cylinders for [[medical]], [[welding]], and other uses.
* Various industrial, manufacturing, and building processes require [[compressed air]] to power [[pneumatic tools]].
* In the manufacturing and [[blow moulding]] of PET [[plastic bottles]] and containers.
* Some aircraft require compressors to maintain [[cabin pressurization]] at altitude.
* Some types of [[jet engine]]s—such as [[turbojet]]s and [[turbofan]]s—compress the air required for fuel combustion. The jet engine's [[turbine]]s power the combustion air compressor.
* In [[underwater diving]], [[self-contained breathing apparatus]], [[hyperbaric oxygen therapy]], and other life support equipment, compressors provide pressurised [[breathing gas]] either directly or via high pressure gas storage containers, such as [[diving cylinder]]s.<ref name=evil>{{cite journal |title=Compressed breathing air – the potential for evil from within |vauthors=Millar IL, Mouldey PG |year=2008 |volume=38 |issue=2 |pages=145–51 |journal=Diving and Hyperbaric Medicine |publisher=[[South Pacific Underwater Medicine Society]] |url=http://archive.rubicon-foundation.org/7964 |access-date=2009-02-28 |pmid=22692708 |url-status=usurped |archive-url=https://web.archive.org/web/20101225063245/http://archive.rubicon-foundation.org/7964 |archive-date=2010-12-25 }}</ref><ref name=oxyhackers >{{cite book |author=Harlow, V |title=Oxygen Hacker's Companion |publisher=Airspeed Press |year=2002 |isbn=0-9678873-2-1}}</ref> In [[surface supplied diving]], an air compressor is generally used to supply low pressure air (10 to 20 bar) for breathing.
* [[Submarine]]s use compressors to store air for later use in displacing water from buoyancy chambers to adjust buoyancy.
* [[Turbocharger]]s and [[supercharger]]s are compressors that increase [[internal combustion engine]] performance by increasing the mass flow of air inside the cylinder, so the engine can burn more fuel and hence produce more power.
* [[Rail transport|Rail]] and heavy [[road transport]] vehicles use [[compressed air]] to operate [[Air brake (rail)|rail vehicle]] or [[Air brake (road vehicle)|road vehicle]] brakes—and various other systems ([[door]]s, [[windscreen wiper]]s, [[engine]], [[gearbox]] control, etc.).
* Service stations and auto repair shops use compressed air to fill pneumatic [[tire]]s and power pneumatic tools.
* [[Fire piston]]s and [[heat pump]]s exist to heat air or other gasses, and compressing the gas is only a means to that end.
* Rotary lobe compressors are often used to provide air in pneumatic conveying lines for powder or solids. Pressure reached can range from 0.5 to 2 bar g.<ref>{{cite web|url=http://www.powderprocess.net/Equipments%20html/Blowers.html|title=Blowers (Roots)|work=Engineering resources for powder processing industries|publisher=www.powderprocess.net|access-date=15 August 2017|url-status=live|archive-url=https://web.archive.org/web/20170814175023/http://www.powderprocess.net/Equipments%20html/Blowers.html|archive-date=14 August 2017}}</ref>
