FIGURE 1 - AD-IP™INTEGRAL PURGE AIR DRYER

DESCRIPTION

The function of the Bendix® AD-IP™integral purge air dryer is to collect and remove air system contaminants in solid, liquid and vapor form before they enter the brake system. It 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 AD-IP™air dryer consists of a desiccant cartridge secured to a die cast aluminum end cover with a single, central bolt. The end cover contains a check valve assembly, safety valve, heater and thermostat assembly, three pipe thread air connections and the purge valve assembly. The removable purge valve assembly incorporates the purge valve mechanism and a turbo charger cutoff feature that is designed to prevent loss of engine “turbo” boost pressure during the purge cycle of the AD-IP™air dryer. For ease of serviceability, all replaceable assemblies can be replaced without removal of the air dryer from its mounting on the vehicle.

The AD-IP™air dryer has three female pipe thread air connections identified as follows:

Air Connection Port ID	Function/Connection
CON 4	Control Port (purge valve control
	& turbo cutoff).
SUP 11	Supply Port (air in).
DEL 2	Delivery Port (air out).
