Air dryer
The compressed air system is equipped with an air dryer. It
separates damp from the air, which prevents valves in the
system from freezing. Depending on the bus model, the air
dryer has either ”one tower” or ”two tower”. In other words it
has either one or two drying agent reservoirs. The illustrat-
ed air dryer has a drying agent cartridge under a cover. The
cover is held in place with four screws.
Separated water is automatically drained away. Dehumidi-
fication of the compressed air occurs through the ceramic/-
a filter. It/they should be changed every other year or when
oil or water is found after draining the compressed air tanks.
See the previous page.
The best time for inspection of the air dryer is late summer,
in good time before the start of the winter period.
Changing drying agent reservoir.
The air dryer is located in front of the left drive wheel. When
changing, please follow the instructions supplied with the
new drying agent reservoir/s carefully.
