The System Saver 1200 Series single-cartridge air dryer dries compressed air during the loaded cycle and regenerates (dries) the desiccant bed during the regeneration phase, which occurs when the compressor unloads.

Note that there is no system regeneration valve used on the “P” series air dryer and port 22 is drilled and tapped for connection to the purge tank.
