From time immemorial the air compressors have been part and parcel of electro mechanical industry and have been facilitating a number of important functions in the field of automobile industry, mechanical industry, and other commercial fields. These are an important part of the commercial and residential areas where these air compressors are used into important electrical and mechanical systems like refrigerators, coolers, air conditioners and also the bike you ride. These equipments are popular because they offer clean, convenient, safe and flexible natural resource which can be used permanently in different applications to increase the efficiency and functionality of the equipment.The equipment is very convenient in facilitating the change of state of air from gaseous state to kinetic energy and therefore finds useful application in many devices. This change of state is done by the compressing of the air in gaseous state after which it is again released but in sudden gushes of air which surely means the change has been done into the kinetic state. For making this process more manageable and convenient the air can be easily stored into well structured compressor tanks. In the mechanical industry high pressure compressors are used in various machines and equipments which require quick conversion of the change of this natural source so that the various functions in the machines are better facilitated and equipped. There are various types of compressors available in the market which can be used by the professionals according to the different needs and requirements. These include the oil free compressors too. In these oil free compressors the used air is easily compressed with the help of the given screws and there is no application of an oil seal. These compressors have a much low maximum discharge capability. These are used in medical research and also in the manufacturing of semiconductors.Contrary to oil free compressors the high pressure compressor is used for quick air cooling where the change in energy state results in change in temperature of the room. Thus these compressors are very useful to attain good results. Compact air compressors are also used for personal usage by many consumers as they are easier to carry around and keep safely far away from the reach of the kids I the house. The compact ones function without the traditional storage tanks which are a very important feature in the usual compressors which are used for industrial purposes.
