Aerobell 168 - Maintenance

MAINTENANCE (continued)
! W A R N I N G
To reduce the risk of fire or explosion,
OSHA and NFPA-33 require that solvents
used for exterior cleaning, including bell
cleaning and soaking, be non-flammable
(flash points higher than 100
0 F/37.8 0 C).
Since electrostatic equipment is involved,
these solvents should also be non-polar. Ex-
ample of non-flammable, non-polar solvents
for cleaning are: amyl acetate, methyl amyl
acetate, high flash naphtha, and mineral spir-
its.
Use a solvent compatible with the coating
being applied to clean the exterior of the ap-
plicator . Use VM & P Naphtha 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.
AIR FILTERS / ELEMENT
REPLACEMENT
Introducing air which contains oil, moisture,
and dirt may cause wear and damage to the
bearings. It is the user’s responsibility to moni-
tor the quality of air and to replace the filter
elements as often as necessary. Turbine fail-
ure caused by poor air quality will not be cov-
ered under warranty.

Air Filter
Ransburg Aerobell systems should include a
pre-filter(s) and final filters for all air to the Aer-
obell 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 indica-
tor.
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 in-
dicator 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 ele-
ments be replaced at least every 4 to 6 months.
In plants where heavy amounts of oil and mois-
ture vapor are present in the air lines, a refrig-
erated air dryer may be necessary.
The Aerobell 168 is designed to give dependa-
ble 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 nec-
essary. (Replace elements at least every 4-6
months or more often.)
