The oil content of compressed air is reduced by using the less oil, half oil and no oil machine, but the life of the damaged parts is reduced, the corrosion of the machine and the pipe system and the side effects of the air compressor in the period of running in, the wear stage, and the oil content of the reduced load period. This is a threat to the pursuit of high reliability of automated production line. It should also be stressed that out: from air compressor to oil in the system is not good in any case.
