. . . The benefits of using compressed air include low maintenance costs, easy storage and transportation, and the ability to be used in manufacturing processes that require a high level of cleanliness. Nine out of ten industries use compressed air daily. Compressed air is used in everyday operations of large-scale factories such as those in the aviation or automotive industries or smaller plants such as those operating in the food manufacturing industry. Additionally, tire repair and auto services providers, car mechanics, and dentist, among many others, also use air compressors. Compressed air acts as an energy source for a variety of tools and machinery, and it is often an important and well integrated part of many production processes. However, due to low system efficiency levels, using compressed air requires intensive energy use.
