Oil Free Air Compressors are those compressors that do not use oil for lubrication of different parts and hence eliminate the chances of contamination due to oil. These consist of air and only air that is compressed for use and hence are much smaller and lighter as compared to other conventional tools.
These come with lesser number of parts as a result of which they require lesser maintenance and have a long life. A number of options are available and water or air is used to cool instead of oil. They are a complete and comprehensive source of air and can easily power a variety of tools at a much lower cost.
As they do not use oil, there is no requirement to regularly check the oil level and refill oil, which may cause a delay in completing the job at hand. Some of the companies specializing in Oil Free Air Compressors are as follows:
Ingersoll Rand Compressors – The name has a global presence due to its superior technology and it prides in manufacturing the best of air compressors. Its Rotary Screw Compressors are manufactured for industrial applications as they can operate for sustained periods of time and come with a low initial cost for installing.
