An air compressor is a medium that changes electricity (utilizing gasoline engine, electric motor, diesel, etc.) into potential power supplied in the coerced air known as compressed air. Its primary object is to transmit the cooling in the system under force, distilling the heat it holds. With the compressor, the pressure of low gas changes into the high-pressure gas. There is a wide range of authentic, fuel-efficient, and inexpensive effectual industrial air compressors, for all low, medium or high-pressure devices available in the market with a complete variety of oil-facilitated and oil-free compressors. Air compressors come in allotted devices with quality, custom-make and organized results for the aquatic, railway system and pharmaceutical industries.

Types of Air Compressors

There are four types of air compressors.

  • Reciprocating air compressors are useful displacement devices, that means by reducing the volume, they increase the pressure in the gas. There is a plunger in the rounded shape to help in compressing and replacing the component. When the compressor uses one side of a piston, it is known as single acting whereas if it uses both sides of a disk; it is called double acting.
  • Rotary screw compressors are also positive displacement compressors. The single step spiral or helical lobe oil flooded screw is the most common rotational air compressors. Rotary screw compressors are simple to sustain and work. Variable displacement and speed help in controlling the capacity of this compressor.
  • Centrifugal compressor is a powerful compressor which is entirely contingent on transmitting of power from a moving vane to the air. This compressor makes high-pressure ejection by transforming sharp-cornered impulse divided by the moving blade (dynamic displacement). To accomplish it competently, centrifugal compressor moves at high speed than any other compressors, and it is designed as an oil-free compressor.
  • Scroll compressors are also called scroll pump, radial compressor, and scroll vacuum pump and are used to air compressors. It is widely used in air-conditioned instruments, as an automobile supercharger which is known as a scroll-type supercharger.

Power and fuel alternatives in compressors

Air compressors can work using electricity or are operated through an engine that runs on inflammable power sources such as diesel or gasoline. Mostly, electrical air compressors are used because of the importance of eliminating weary smoke or where gas and diesel are not needed. On the other hand, fuel is used in spite of electrical compressors because of the noise caused by them. Some air compressors are also powered and operated using water which avoids the fuel or electricity issues.

Uses of air compressors

Air compressors have so many uses that are:

  • Aerating the balloons to save power, efforts and time
  • Pumping tires with air to have dense and mobile compressors in the cars
  • Delivering oxygen to patients in hospitals
  • Delivering energy to machines with the help of a large power plant
  • Delivering oxygen to the Scuba divers kit when they are below the sea level
