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.

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
