Description: Genuine Bendix AD-9 Air Dryer
Condition: New
Brand: Bendix 
Part Number: 065647, 065647BXW

Voltage: 12 V

The Bendix® AD-9® and AD-9® PG (with PuraGuard®
coalescing filter) air dryers each consist 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 of engine “turbo” boost pressure during the
purge cycle of the Bendix AD-9 and AD-9 PG air dryers.
For ease of serviceability, the desiccant cartridge and
discharge check valve assembly are screw-in types. The
purge valve housing assembly–which includes the heater
and thermostat assembly–and the discharge check valve
assembly, are serviceable from the exterior of the air dryer;
servicing the screw-in desiccant cartridge requires removal
of the air dryer assembly from the vehicle.
The AD-9 PG air dryer appears identical to the standard
AD-9 air dryer, but contains a coalescing media at
the inlet of the desiccant bed. This coalescing media
provides a higher level of oil removal over the standard
AD-9 air dryer. The AD-9 PG air dryer has all the same
functions of the standard AD-9 air dryer, and is used
where oil is contaminating downstream components.
The Bendix AD-9 PG air dryer can be identified by the
PG label (shown in Figure 1) located on the air dryer
housing.
