AIR FILTERS / ELEMENT
REPLACEMENT
Ransburg Aerobell systems should include a
pre-filter(s) and final filters for all air to the Aerobell
168 unit. The final filter is for bearing air only. All
filters contain elements that must be replaced on
a regular basis to assure clean air. HAF-508 and
RPM-418 filters also contain an automatic drain
and pressure differential indicator.
The pressure differential indicator provides a visu-
al indicator that pops up (becomes more visible)
as the filter element becomes plugged. Replace
the filter elements when the visual indicator be-
comes visible, don’t wait until it pops up fully. As
the elements become plugged, their efficiency
drops. The frequency of filter element change
will depend upon the quality of the plant air. It is
recommended that all elements be replaced at
least every 4 to 6 months.
In plants where heavy amounts of oil and moisture
vapor are present in the air lines, a refrigerated
air dryer may be necessary.
The Aerobell 168 is designed to give dependable
service and extended life. One of the most import-
ant factors in realizing long life is the quality of air. It
is therefore essential for the user to closely monitor
the quality of their air and to properly maintain the
air filters by replacing the filter elements as often
as necessary. (Replace elements at least every
4-6 months or more often.)

† To reduce the risk of fire or explosion.
Solvents used for cleaning must have a
flash point at minimum of 5° C (9°F) greater
than the ambient temperature. It is the end
users responsibility to insure this condi-
tion is met. Since electrostatic equipment
is involved, these solvents should also
be non-polar. Example of non-flammable,
non-polar solvents for cleaning are: amyl
acetate, methyl amyl acetate, high flash
naphtha, and mineral spirits.
† Use a solvent compatible with the coat-
ing being applied to clean the exterior of the
applicator . Use VM & P Naptha as a final
wipe to remove surface conductivity.
† When using a rag to hand wipe the
Aerobell, the turbine air should be off, but
leave both the shaping air and bearing air
turned on. Ensure that rotation has come to
a complete stop.

† Introducing air which contains oil, mois-
ture, and dirt may cause wear and damage
to the bearings. It is the user’s responsibility
to monitor the quality of air and to replace
the filter elements as often as necessary.
Turbine failure caused by poor air quality
will not be covered under warranty.
