 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
