1.5. Important Recommendations
1.5.1. Paint Resistivity
Atomizer PPH 308 is used to spray liquid solventborn paints with a resistivity
WARNING : It is essential to ground the bulkhead union of the paint circuit inside the PPH 308
body.
WARNING : Product supply must be imperatively connected to the ground.
WARNING : The dump line must be imperatively connected to the ground with a sufficient dis-
tance of the atomizer in order to keep the potential (to limit the leakage current).
1.5.2. Compressed Air Quality
The air must be filtered to a level that will guarantee a long life time and prevent any pollution
during painting.
The filter must be installed as close as possible to the facility. The filter cartridges must be
changed regularly to ensure that the air is clean.
PTFE tape or glue should not be used between the filter and the bearing as glue residue or
pieces of PTFE may block the small holes of the air bearing and cause turbine failure.
The inside of hoses supplying air to the atomizer and the ports of the quick-disconnect plate
must be clean and free of any traces of paint, solvent or other foreign matter.
The guarantee does not cover faults caused by unclean, unfiltered bearing air resulting from
disregard of the previous recommendations.
WARNING : If the air is not correctly filtered, the bearing may become fouled resulting in a tur-
bine operating fault. The filtering system used must prevent particles greater than
5 µm in diameter from reaching the bearing.
WARNING : The guarantee does not cover damage caused by foreign matter such as paint,
solvent or other substances entering the air circuits of the PPH 308.
