BPW axles with air suspension

8 PDC shock absorber

B BPPWW PPDDCC sshhoocckk aabbssoorrbbeerr
BPW PDC shock absorbers permit load-dependent
damping and guarantee a constantly high level of
safety and driving comfort irrespective of the load-
ing condition.
The infinitely variable damping adaptation to the
particular loading condition is achieved by a pneu-
matically adjustable proportional valve on the shock
absorber.
The PDC system is based on standard air suspen-
sion and does not require any additional control
PDC air connection electronics, therefore PDC shock absorbers can be
(proportional valve)
integrated with, or retrofitted to existing BPW air
suspension units without difficulty.

The PDC shock absorber is available in two ver-
sions, matched to the bag pressures of BPW 30
and BPW 36 air bags. The installation must be
adapted to the shock absorber lengths.

Make sure there is sufficient clearance from the air
suspension hanger bracket during installation.

Shock absorbers should only be fitted and changed
as a complete axle set. A multiple axle vehicle can
be fitted with different units on individual axles.
