Find Air Compressor Providers, Agents, Companies at Eworldtrade An air compressor converts power into potential energy. The difference between an air compressor and air pump is that an air pump simple pumps the air from one context to another. Air pumps are also much slower, and less expensive to own and operate. An air compressor holds the air in the tank until it is called into use. Most air compressors work with the help of a reciprocating piston. There are many types of air compressors that are commonly used in various industries. Every now and then, an air compressor needs to be replaced. The only trouble is, air compressors can sometimes be on the more expensive side and if you don't find a high quality one in the first try, you know you're going to need to replace it again soon as well.
