Specially adapted rubber bushes prevent any
significant vibration transfer to the bodywork.
Ensure that rubber bushes are installed
correctly!
Both halves of the metal box housing are
fitted with a seal. This seal is essentially for
soundproofing. As the compressor sucks and
vents the air out of the metal box, it is
designed to allow a certain degree of leakage.
The air supply unit
The following components are contained in a
metal box inside the air supply unit:
– the V66 compressor with integrated air
dryer and discharge valve N111,
– transverse check valves N150 and N151,
– control unit J197
– and the relay for compressor J403
The components listed above are housed in a
special polyurethane foam (PUR foam)
insulation mat to ensure vibration and
acoustic damping. The insulation mat is
designed to fix the positions of the individual
components within the metal box.
