6 Periodic maintenance work / 6.2 Cleaning the compressor during
operation
Pressurized air from the compressor casing (72000) of the turbocharger passes through the
pipe (02) to the water pressure vessel (27000). As soon as the valve activator (03) is activ-
ated, water is pressed into the pipe (01) and routed to the filter silencer or air suction
branch.
The water does not act as a solvent. The coating is removed by the mechanical action of the
impacting droplets.
