9. HALDEX CONDENSER - SEPARATOR
The Consep Air Condenser-Separator is located
in the rear wheelhousing, fore of drive axle
(Figure 16). When present, the Consep is
mounted in the air line between the compressor
and the air dryer. It condenses, separates and
removes 90% of the oils, liquids and other
contaminants. It reduces corrosion and possible
failure of air brake system components caused
by contamination and significantly increases the
air dryer desiccant life.

FIGURE 17: CONSEP OVERVIEW
The automatic heated drain valve installed on
the Consep ensures that liquids are removed
upon each brake application for optimum
performance. The drain valve’s integrated filter
prevents damage from large debris.
The automatic drain valve activates when the
rear stop lights turn ON, with the prerequisite
conditions of having a vehicle speed greater
than 2 mph and the engine running.
The solenoid remains energized simultaneously
with activation of the rear stop lights to heat up
air output to prevent it from freezing. However,
Multiplex programming will ensure that the
solenoid remains energized for at least of 45
seconds but not longer than 5 minutes.
9.1 PERIODIC INSPECTION
The Consep requires little maintenance during
its long service life. The Consep must be
inspected periodically for proper operation. The
interval between inspections is determined by
the type of service. High compressor duty cycles
and high temperatures can cause a buildup of
carbon in the condenser, drain valve and filter.
This contamination must be removed for proper
operation.
For more information on the periodic inspection,
refer to Haldex Consep Condenser Separator,

CD.
10. AIR LINES
Nylon-reinforced tubing and flexible hoses are
used to connect the units in the pneumatic
system, including air brake system, suspension
system and accessory systems such as the
entrance door, air as, etc. Furthermore, the
nylon tubing is color coded to ease identification.
Refer to the following table for the complete color
identification code. Service instructions for each
type of air line are also provided under the
applicable headings.
