There are many types of air compressors in existence. The type of air pump in the compressor is what distinguishes it from others. Whatever the case, it is important to note that some air compressors are portable while others are stationery. A portable air compressor can be used for spray-painting purposes whenever you need paint repairs away from the workshop. The compressor can also be used to fix punctured tires off-site. Most mobile mechanics have portable compressors.
It is important to note that portable compressors usually have smaller cylinders for storing compressed air. They also have pumps that are powered by a gasoline engine. After all, there might not be an electric socket outlet to power an electric motor by the roadside. Portable air compressors may also have wheels to make it easier for the user to move the compressor from one point to another.
