The System Saver 1200 Series single-cartridge wabco 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 wabco air dryer and port 22 is drilled and tapped for connection to the purge tank.

A cross reference listing means that this wabco air dryer is a suitable replacement for the part numbers listed. Some changes in plumbing and/or installation may be required.
