What are Screw Compressors?
If an air compressors do not make use of oil, then you have an oil free or a screw air compressor. This type does not have the benefit of an oil seal and operates through the action of screws.

There are other uses of oil free compressors including medical research, and the food industry where it is unacceptable to have oil spills and run-offs. These types of compressors are also used in construction, auto manufacturing and repair industries to a certain degree.
The lifespan of screw air compressors are shorter than that of oil air compressors.
