DESCRIPTION

The function of the  Integrated Solution Air Dryer (AD-IS®)
and Reservoir System is to provide heavy vehicles with an
integrated 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.
