To provide a purge system capable of extending the life of a drying agent in an air dryer.SOLUTION: A purge system includes: a main tank; a compressor; an air dryer having a purge valve; an electromagnetic valve which supplies an instruction pressure to the purge valve and stops the supply of the instruction pressure; a governor which supplies the instruction pressure toward the electromagnetic valve and stops the supply of the instruction pressure according to a tank pressure as a pressure in the main tank; and a control section which controls the electromagnetic valve to allow the electromagnetic valve to supply the instruction pressure to the purge valve while bypassing the governor when there is satisfied at least one of conditions that prescribed operation is detected, that the amount of air supplied to the air dryer by the compressor in a prescribed period is determined to be equal to or greater than a first threshold, and that a period of time from a time when the governor starts the supply of the instruction pressure until a time when the governor stops the supply of the instruction pressure is shorter than a reference period of time.SELECTED DRAWING: Figure 1

    【課題】エアドライヤの乾燥剤の寿命を長くすることができるパージシステムを提供することを目的とする。【解決手段】パージシステムは、メインタンクと、コンプレッサと、パージバルブを有しするエアドライヤと、指示圧のパージバルブへの供給および指示圧の供給の停止を行う電磁弁と、メインタンク内の圧力であるタンク圧に応じて、電磁弁に向けた指示圧の供給および指示圧の供給の停止を行うガバナと、所定の操作が検出されたこと、所定期間におけるコンプレッサによるエアドライヤへのエア供給量が第1の閾値以上であると判定したこと、および、ガバナが指示圧の供給を開始した時刻からガバナが指示圧の供給を停止した時刻までの時間が基準時間未満であることの少なくともいずれかがの場合、電磁弁にガバナを介さずに指示圧をパージバルブに供給させるように電磁弁を制御する制御部と、を備える。【選択図】図1
