The device that converts energy through the method of air compression into kinetic energy that can trigger large blasts of air when needed is called an air compressor. Power usually comes from a diesel engines, an electric motors, or gasoline engines. Air compressors are popular and used in a variety of industries for the safe, clean, and convenient use of air. Air compressor types can be classified based on positive displacement or negative displacement. They are as follows: • Piston compressors or reciprocating compressors : These are the most common type of positive displacement compressors. Power ranges from fractional to very high. The air is fills into the chamber and then the volume of the chamber is reduced, creating compression and thus releasing energy. The internal components include valves, cylinders, crankshafts, pistons, and housing blocks. • Centrifugal compressors : This is not a positive displacement compressor, it uses impellers rotating at a very high speed, it acc
