BPW Shock absorber 5

General

PDC
The BPW PDC ( Pneumatic Damping Control ) shock
absorber improves driving properties and comfort – O
whatever the load.
The best damping, better road safety, lower maintenance
costs – given all these reasons, you don’t need to think SL
long and hard before fitting or retrofitting BPW air
suspension systems with PDC.

Function
The disadvantage with conventional shock absorbers is AC
that their characteristics can only be optimally adapted to
one loading condition (usually fully laden). PDC detects
the actual loading condition via the air suspension and
adapts itself smoothly. This improves driving safety at
the same time as reducing the strain on the chassis and
the vehicle, in particular when the trailer is empty or only
partly laden.
PDC is virtually essential in high-value vehicles and when
carrying sensitive cargoes. Vehicle maintenance costs
are reduced.
The cargo and the carriageway are also subjected to
fewer shock loads.
PDC is connected to the BPW air suspension system and
does not require any electronic control systems.

 When using PDC shock absorbers, a washer must ! " # $ ! " # $
be installed between the support or spring seats
and each PDC, also shorter lock nuts must be
used.
