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 filter 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
prefilter(s) and final filters for all air to the Aerobell
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. RPM-417 and
RPM-418 filters 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 filter element becomes plugged. Replace the
filter elements when the visual indicator becomes
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.

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 filters by replacing the
filter 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 flush cleaning cycle.
To reduce the risk of fire or explosion, the solvents
used for exterior surface cleaning must have flash
points above 100°F (37.8°C). Since electrostatic
equipment is involved, these solvents must also
be non-polar.
Solvents used for equipment flushing should have
flash 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 flush cycle. Flushing should be done
before any down time or break in production. A bell
flush 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 flushing through the bell.
2. If there is any remaining paint build-up on any
areas of the bell after flushing, 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.
