PROBLEM TO BE SOLVED: To provide an air compressor system using a rotary type air compressor, preventing deterioration of lubricant oil to keep a long life, even if it is used in high temperatures and high humidity environment. SOLUTION: The rotary type air compressor 30 is operated by operation of a motor 31, and sucks atmospheric air and discharges compressed air. Lubricating oil mixed in the compressed air is separated by an oil separator 32. The compressed air from which oil is separated is cooled by an after-cooler 33, and after it is dehumidified in a dehumidifier 34, it is sent to an original air reservoir 36 to be stored. A bypass pipe line 5 in which a throttle valve 6 is interposed connects the branch point 2 of a pipe line 1 to the junction 4 of a suction pipe line 3. Therefore, a part of dried air is sucked into the air compressor 30 by passing through the bypass pipe line 5. As a result, the air compressor 30 sucks the mixed gas of the atmospheric air with high temperatures and high humidity and the dried air having passed through the bypass pipe line 5.
