Air compressors convert energy, created by a motor or engine, into kinetic energy in the form of compressed air. The air compressor’s engine forces air into the tank until it reaches a specific pressure point and then shuts off. When the air compressor is used, and thus this built-up pressure is released, it turns itself back on to repressurise once the pressure gets below a specific point. Air compressors can be used for various inflation jobs such as inflating tyres. They are also used in construction applications like powering drills and other functions such as spray painting.
