A regeneration passage (14) is branched from a connection point (5A) on a discharge/supply pipeline (5), the connection point (5A) being located between the air dryer (6) and the compressor (2), and is connected to the supply route (12). A regeneration open/close valve (15) that allows moist air, which is obtained after dryer regeneration, to circulate at least from the connection point (5A) toward the supply route (12) is provided on the regeneration passage (14).
