Compressed Air System
The compressed air system is comprised of
multi-air storage tanks
. The
primary tank
stores and supplies
air for the
rear brakes
, the secondary tank stores and supplies air for the
front brakes
.
When air is compressed it becomes hot. As it cools, condensed moisture forms in the system. The air system is
equipped with an air dryer to remove most of this moisture. The dryer has an automatic moisture ejector that
releases the trapped moisture back into the atmosphere. However, some moisture will form in the system
beyond the dryer, and make its way into the storage tanks. As moisture collects in the
primary
and
secondary
tanks, it displaces the area needed for air storage, thus requiring that the tanks be
drained periodically
.
The air system is equipped with
air tank drains
conveniently located in the compartment with the DEF tank.
Each drain is attached to a different
tank. These drains should be
opened regularly
for a few seconds to
remove
any moisture trapped in the tanks.
Air Dryer
The Tiffin PowerGlide chassis air brake system features a Haldex Purest air
dryer (Figure 3-3), which removes the condensed moisture from
compressed air. The air dryer is equipped with a desiccant cartridge that
needs to be changed
every 36 months.
The dryer is located on the driver's
side (LH) frame rail (behind the rear axle).

Warning
Air tanks should be bled of all pressure any time you perform work on the air system.
