#Air compressor free#
Oil free rotary screw air compressors are the ones which are air cooled and water cooled and also provides the same flexibility as that of an oil flooded rotaries whenever the oil free air is required. The rotary screw air compressors which are found to be oil free, utilizes the specially designed air ends in order to compress the air without the presence of oil in the compression chamber in order to yield true oil free air. There are various advantages of using a rotary screw compressor which includes smooth, pulse-free air output in a compact size along with a high output volume over a long life. As soon as the capacity of the compressor is reduced, the slide valve gets opened by passing a required portion of the compressed air back to the suction. There is also found a slide valve which is located inside the casing.
The capacity control of such compressors is accomplished by the varying speed as well as the varying compressor displacement. Rotary screw air compressors are found quite easy to maintain and operate. Due to the internal cooling system, these are the air compressors which are designed for continuous use and also range in power from 5 horsepower to 350 horsepower. The air which gets trapped within the two opposing rotors, is responsible for building up pressure within the housing.
These are the compressors which generate energy via two internal rotors which gets turned in the opposite direction. These compressors are found to be typically large as well as industrial-sized machines which can either be lubricated with oil or can even run oil-free. These are some of the easiest types of air compressors in terms of taking its care, as these are the machines which are equipped with an internal cooling system and does not require high maintenance. Rotary screw compressors are referred to as those compressors which are a common type of displacement compressor.
