AIR FILTERS / ELEMENT
REPLACEMENT
> Introducing air which contains oil, mois-
ture, and dirt may cause wear and damage
to the bearings. It is the user's respon-
sibility to monitor the quality of air and to
replace the lter elements as often as nec-
essary. Turbine failure caused by poor air
quality will not be covered under warranty.
Ransburg Aerobell systems should include a
prelter(s) and nal lters for all air to the Aerobell
unit. The nal lter is for bearing air only. All
lters contain elements that must be replaced on
a regular basis to assure clean air. RPM-417 and
RPM-418 lters also contain an automatic drain
and pressure differential indicator.
The pressure differential indicator provides a visual
indicator that pops up (becomes more visible) as
the lter element becomes plugged. Replace the
lter elements when the visual indicator becomes
visible, don’t wait until it pops up fully. As the
elements become plugged, their efciency drops.
The frequency of lter 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.

REPLACEMENT ELEMENTS
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 is designed to give dependable
service and extended life. One of the most
important 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 lters by replacing the
lter elements as often as necessary. (Replace
elements at least every 4-6 months or more often.)
Atomizer Bell Assembly
Inspect the atomizer bell assembly for any damage,
wear, or paint build-up every day.
BELL CUP CLEANINGS
Always verify that high voltage is off and that the
atomizer bell is spinning before performing any
type of bell ush cleaning cycle.
To reduce the risk of re or explosion, the solvents
used for exterior surface cleaning must have ash
points above 100°F (37.8°C). Since electrostatic
equipment is involved, these solvents must also
be non-polar.
Solvents used for equipment ushing should have
ash points equal to or higher than those of the
coating material being sprayed.
1. The atomizer bell will normally be fully cleaned
during a bell ush cycle. Flushing should be done
before any down time or break in production. A bell
ush cycle may also be required while spraying
batch parts of the same color. Verify that high
voltage is off and that the atomizer bell is spinning
before ushing through the bell.
2. If there is any remaining paint build-up on any
areas of the bell after ushing, the bell should be
removed for hand cleaning. The bell's leading
edge, splash plate, and serration cuts are some
examples of areas for special attention.
