Compact Air Processing Unit - Integrating air dryer,
multi-circuit protection valve and oil pre-separator

Building on WABCO’s reputation for
robust and state-of-the-art air
processing technology, the new
Compact APU from WABCO meets
today’s market need for a small, totally
integrated one-body APU solution
offering multiple functionality and high
performance at optimum cost.

It can be used for standard truck and
bus applications requiring up to two
pressure levels. Due to the modular
design, the Compact APU can be
tailored to meet customers’ specific
requirements. Furthermore, it
enables vehicle manufacturers to
implement only one variant for a whole
vehicle platform.

The integration of air dryer and multi­circuit protection valve in one compact
body, simplifies the piping which
reduces assembly costs and increases
the reliability of the entire system.

The Compact APU features an
innovative upstream oil pre-separation
unique to WABCO. Making use of

centrifugal forces and impact effects,
it filters out the bigger oil and water
droplets before compressed air reaches
the air drying cartridge, improving
its efficiency.
