IMPORTANT! When servicing, note that standard
AD-RP air dryers or air dryer cartridges may be
serviced with PuraGuard oil coalescing air dryers or
cartridges. The PuraGuard oil coalescing air dryers or
cartridges, however, must only be serviced with like
replacements.
Note: Unless otherwise stated in this manual, AD-RP
air dryer refers to both the standard and PuraGuard oil
coalescing remote purge air dryers.
The remote purge designation is used because the
AD-RP air dryer uses a small air volume, separate
from the air brake system, to perform the purge or
regenerative function.
The AD-RP air dryer consists of two major component
groups—a spin on desiccant cartridge assembly, and a
die cast aluminum body assembly. The desiccant cartridge
is self-contained and serviced as a complete assembly.
DESCRIPTION
The function of the Bendix ® AD-RP ™ remote purge air dryer
— and the AD-RP ™ remote purge air dryer with PuraGuard ®
oil coalescing technology — is to collect and remove air
system contaminants in solid, liquid and vapor form before
they enter the brake system. The dryer provides clean, dry
air to the components of the brake system which increases
the life of the system and reduces maintenance costs. Daily
manual draining of the reservoirs is eliminated.
The Bendix AD-RP PuraGuard oil coalescing air dryer
has an identical appearance to the standard AD-RP air
dryer but contains a coalescing media at the inlet of the
desiccant bed. The coalescing media provides a higher
level of oil removal over the standard AD-RP unit. The
AD-RP PuraGuard oil coalescing air dryer has all of the
same functions as the standard AD-RP air dryer and is
used in applications where lower oil concentration levels
are required.
