To provide a purge system which reduces the frequency of regeneration operation of a drying agent in an air dryer.SOLUTION: A purge system includes: a main tank; a compressor; an air dryer which has a purge valve and supplies, to the main tank, air discharged from the compressor; a governor which supplies an instruction pressure from the main tank and stops the supply of the instruction pressure according to a tank pressure as a pressure in the main tank; an electromagnetic valve which switches between the closing and the opening of piping connecting the governor and the purge valve; and a control section which allows the electromagnetic valve to close the piping when there is satisfied at least one of conditions that prescribed operation is detected, that the amount of the air supplied to the air dryer by the compressor in a prescribed period is determined to be less 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 equal to or longer than a reference period of time.SELECTED DRAWING: Figure 1

    【課題】エアドライヤでの乾燥剤の再生動作の頻度を少なくす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、コンプレッサから吐出されたエアをメインタンクに供給するエアドライヤと、メインタンク内の圧力であるタンク圧に応じて、メインタンクからの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、ガバナとパージバルブとを接続する配管の閉塞および開放を切り替える電磁弁と、所定の操作を検知したこと、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の閾値よりも少ないと判定したこと、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以上であることの少なくともいずれかが満たされた場合、電磁弁に配管を閉塞させる制御部とを備える。【選択図】図1
