AIR DRYER AND RESERVOIR SYSTEM (MODEL: BENDIX AD-
IS)
DESCRIPTION
EN0680202C100001
TABLE 1 - PORT DESIGNATIONS
The function of the Integrated Solution Air Dryer (AD-IS

) and Reservoir System is to provide heavy vehicles with an inte-
grated vehicle air dryer, purge reservoir, governor and a number of the charging valve components in a module. These have
been designed as an integrated air supply system.
The AD-IS

air dryer and reservoir system collects and removes 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. The necessity for daily manual draining of the reservoirs is eliminated.
