DESCRIPTION
The function of the Bendix ® AD-9 ® and AD-9 ® IPC Integrated
PuraGuard ® Coalescing air dryers is to collect and remove
air system contaminants in solid, liquid, and vapor form
before they enter the brake system. They provide 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-9 and AD-9 IPC Integrated PuraGuard
Coalescing air dryers consists of a desiccant cartridge
and a die cast aluminum end cover secured to a cylindrical
steel outer shell with eight cap screws and nuts. The end
cover contains a check valve assembly, a safety valve,
three threaded air connections, and the purge valve
housing assembly. The removable purge valve housing
assembly incorporates a purge valve mechanism and a
turbocharger cut-off feature that is designed to prevent loss
