What is an air compressor?

An air compressor is a device that converts power (usually from an electric motor, a diesel engine, or a gasoline engine) into kinetic energy by compressing and pressurizing air. The compressed air can power pneumatic tools, inflate tires and perform other purposes. Here is a general overview of how an air compressor works:

  • The electric motor, gasoline engine, or diesel engine powers a piston or a rotary-screw mechanism, which begins to compress the air.
  • As the air is compressed, it is forced into a storage tank or cylinder.
  • The compressed air is held in the tank until it is needed.
  • When the compressed air is needed, a valve opens and allows the pressurized air to flow out of the tank and through an air hose to the tool or device being powered.
  • As the compressed air is used, the pressure in the tank decreases. When the pressure drops to a certain level, the air compressor will automatically start up again to restore the pressure.

There are several types of air compressors, including reciprocating (piston) compressors, rotary-screw compressors, and centrifugal compressors. The specific design and operation of the compressor will depend on the type of compressor it is.

Types of air compressors

Here is a brief overview of the different types of air compressors:

  • Reciprocating (piston) compressors: These compressors use pistons to compress the air. They are commonly used in small- to medium-sized applications, such as powering tools in a workshop or inflating tires.
  • Rotary-screw compressors: These compressors use two interlocking helical screws to compress the air. They are more efficient and have a longer lifespan than reciprocating compressors, and are often used in industrial and manufacturing settings.
  • Centrifugal compressors: These compressors use a spinning impeller to accelerate and compress the air. They are used in high-volume applications, such as in natural gas processing and power plants.
  • Diaphragm compressors: These compressors use a flexible diaphragm to compress the air. They are often used in applications where the compressed air needs to be kept free of oil, such as in the food and beverage industry.
  • Scroll compressors: These compressors use a pair of spiral-shaped plates to compress the air. They are relatively small and quiet, making them a popular choice for use in residential air conditioning systems.
