Due to adiabatic heating, air compressors require some method of removing waste heat. This is usually some form of air or water cooling, although some compressors (particularly rotary ones) may be oil cooled (which is in turn cooled with air or water).[5] Atmospheric changes are also considered during compressor cooling. The type of cooling is determined by considering factors such as inlet temperature, ambient temperature, compressor power and application area. There is no single type of compressor that can be used for any application.

Air compressors have a variety of uses, including: supplying clean, high-pressure air to fill gas tanks, supplying clean, moderate-pressure air to a submerged diver with surface supply, supplying clean, moderate-pressure air to drive some pneumatic HVAC control system valves of office buildings and schools, supplying a large amount of moderate-pressure air to power pneumatic tools, such as pneumatic hammers, filling high-pressure air (HPA) tanks, filling tires, and producing large volumes of moderate-pressure air. for large-scale industrial processes (such as oxidation for petroleum coking or cement plant bag purge systems).[6]​.

Most air compressors are reciprocating piston, rotary vane, or rotary screw. Centrifugal compressors are common in very large applications, while rotary screw, scroll[7]​ and reciprocating air compressors are preferred for smaller portable applications.

Air compressors are designed to use a variety of energy sources. While electric and gasoline/diesel air compressors are among the most popular, air compressors that use vehicle engines, power take-offs, or hydraulic ports are also commonly used in mobile applications.[8]​.

The power of a compressor is measured in HP (horsepower) and CFM (cubic feet per minute of intake air).[9]​ The gallon size of the tank specifies the volume of compressed air (in reserve) available. Gasoline/diesel compressors are widely used in remote areas with electricity access problems. They are noisy and require ventilation for exhaust gases. Electric compressors are widely used in production plants, workshops and garages with permanent access to electricity. Common workshop or garage compressors are 110-120 volts or 230-240 volts. Depending on the size and purpose, compressors can be stationary or portable.

To ensure that all types of compressors operate efficiently without leaks, it is imperative to perform routine maintenance such as monitoring and replacing air compressor accessories. Most air compressors can be operated following the instructions in the included manual,[10]​ in addition to having the appropriate spare parts for proper maintenance[11]​.
