FIGURE 1 - BENDIX® AD-RP™REMOTE PURGE AIR DRYER
DESCRIPTION
The function of the Bendix® AD-RP™remote purge air dryer
—and theAD-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.
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.
