system is to collect and remove air system contaminants
in solid, liquid and aerosol form before they enter the brake

Both air dryer and reservoir systems provide 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.
