From the Latin compressor, a compressor is what compresses (presses, oppresses, reduced to a lower volume). The term is used to denote any machine which, thanks to an increase in pressure, is able to move compressible fluids such as gases.
Advantages of using air compressor:
The compressor not only manages to move fluids, but also changes the density and temperature of the compressible fluid. Compressors are used in different fields, such as in conditioners (air conditioning units), refrigerators, turbojets and some power generation systems.
Depending on the energy exchange method, compressors can be grouped into different types, such as reciprocating or piston compressors (whose valves open and close to suck or compress gas), rotary compressors (with rotating screws) or centrifugal compressors (which use a dynamic rotor), among others.
On the other hand, by compressor is meant any computer program (software) making it possible to reduce the size of a digital file. To achieve compression, this software looks for possible redundancies in the files in order to eliminate them, which makes it possible to delete information while reducing the weight (the size of the files) without loss of quality.
Finally, an audio compressor is an electronic sound processor capable of reducing the dynamic range (or range) of a signal. These compressors work by attenuating the electrical signal to a certain number of decibels to protect certain equipment / devices from possible signal peaks or to conceal the error of an overdriven sound.
These compressors are used in concerts (direct sound) and musical recordings. If a bassist hits the strings with a finger during a live performance, the effect generated can damage the amplifier in the absence of a compressor.
A word of advice:
If you are going for large fluid-aire dynamics in your garage from used air compressors, you will definitely want to invest in mounting a quality air hose reel, in a central location, for ease of use and organization.
