There are many methods of compressing gas, each different. All are quite complicated. They can be powered by either combustible fuel or electricity, depending of application.
Centrifugal Compressors:
Centrifugal compressors use a rotating disk or impeller in a shaped housing to force the gas to the rim of the impeller, increasing the velocity of the gas. A diffuser (divergent duct) section converts the velocity energy to pressure energy. They are primarily used for continuous, stationary service in industries such as oil refineries, chemical and petrochemical plants and natural gas processing plants. Their application can be from 100 horsepower (75 kW) to thousands of horsepower. With multiple staging, they can achieve extremely high output pressures greater than 10,000 psi (69 MPa).
Many large snow-making operations (like ski resorts) use this type of compressor. They are also used in internal combustion engines as superchargers and turbochargers. Centrifugal compressors are used in small gas turbine engines or as the final compression stage of medium sized gas turbines.
Reciprocating Compressors:
Reciprocating compressors use pistons driven by a crankshaft. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines. Small reciprocating compressors from 5 to 30 horsepower (hp) are commonly seen in automotive applications and are typically for intermittent duty. Larger reciprocating compressors well over 1,000 hp (750 kW) are commonly found in large industrial and petroleum applications. Discharge pressures can range from low pressure to very high pressure (>18000 psi or 180 MPa). In certain applications, such as air compression, multi-stage double-acting compressors are said to be the most efficient compressors available, and are typically larger, and more costly than comparable rotary units. Another type of reciprocating compressor is the swash plate compressor, which uses pistons which are moved by a swash plate mounted on a shaft.
Gas compressors work by increasing the pressure of a gas, which reduces its volume. This is typically achieved by using a piston, rotor, or impeller to compress the gas within a chamber. As the gas is compressed, its molecules move closer together, resulting in a higher pressure and temperature. This compressed gas can then be used for various applications such as powering machinery or refrigeration.
Compressors work by reducing the volume of a gas to increase its pressure, which makes the gas more energy-dense. This is achieved by squeezing the gas into a smaller space, which causes the gas molecules to collide more frequently and increase in pressure. The compressed gas can then be used for various applications, such as powering tools, refrigeration, or air conditioning.
Rotary compressors use rotating motion to compress air within a closed system, while centrifugal compressors rely on centrifugal force to increase gas pressure. Rotary compressors are typically more compact and can provide higher pressure ratios, while centrifugal compressors are better suited for high-volume applications with relatively low pressure ratios.
An air compressor is used to compress air, typically for tools or inflation purposes, while a gas compressor is used to compress gases such as natural gas, hydrogen, or nitrogen for various industrial applications. Gas compressors are designed to handle specific gas compositions and are used in processes like gas transmission, storage, and processing, while air compressors are more commonly used in general-purpose applications.
Hermetic compressors rely on refrigerant gas for cooling. When drawing deep vacuums during the recycling or recovery process, there may not be enough refrigerant gas circulating to adequately cool down the compressor. This can lead to overheating of the compressor and potential damage to the equipment.
Adiabatic compression is a process in thermodynamics where the volume of a gas is reduced without any heat being added or removed from the system. This leads to an increase in the temperature and pressure of the gas. This process is often used in compressors and pumps.

This category covers firms primarily engaged in manufacturing air and gas compressors for general industrial use, and non-agricultural spraying and dusting equipment.
The gas compressors cost a lot more to maintain. While the electric units will cost a lot less, and also be able to lift a lot more than the gas units.
The term CNG stands for Compressed Natural Gas. This is compressed by special compressors for use in automobiles, household and other less-polluting substitute fuel applications in industry.
what is the meaning of compressor.and how does compressor work.and how many types of compressors
Not much. Both compress gas: the one "air", t'other some freon-based gas.
Rotary compressors use rotating motion to compress air within a closed system, while centrifugal compressors rely on centrifugal force to increase gas pressure. Rotary compressors are typically more compact and can provide higher pressure ratios, while centrifugal compressors are better suited for high-volume applications with relatively low pressure ratios.
