This is to announce that the desiccant cartridge used in all new AD-4 and AD-9 Air
Dryer assemblies has been reduced in height by approximately ¾”. The height
reduction was achieved by bringing several internal cartridge components closer
together. Formerly unused air space within the cartridge housing has been eliminated
by this redesign and allowed the ¾” reduction in height. The amount of desiccant used
in the cartridge remains unchanged.

By reducing the cartridge height, an increase in usable purge volume was achieved,
along with a slight weight reduction. The old and new cartridge designs are completely
interchangeable. The part numbers for new service and re-manufactured exchange
cartridges, for both the AD-4 and AD-9, remain the same. See the chart below for
reference. All service new cartridges will be the shorter version while either design
cartridge will be supplied for re-manufactured exchange purchases.
