Smoking must never be allowed in the spray area.
The high voltage supplied to the atomizer must be
turned off prior to cleaning, ushing or maintenance.
Spray booth ventilation must be kept at the rates
required by NFPA-33, EN 16985, country, and local
codes. In addition, ventilation must be maintained
during cleaning operations using ammable or
combustible solvents.
Electrostatic arcing must be prevented. Safe
sparking distance must be maintained between the
parts being coated and the applicator. A distance of
1 inch for every 10KV of output voltage is required

Spray Area /
High Voltage
Equipment
There is a high voltage device
that can induce an electrical
charge on ungrounded objects
which is capable of igniting
coating materials.
Inadequate grounding will
cause a spark hazard. A
spark can ignite many coating
materials and cause a re
or explosion.
Parts being sprayed and operators in the spray
area must be properly grounded.
Parts being sprayed must be supported on
conveyors or hangers that are properly grounded.
The resistance between the part and earth ground
must not exceed 1 megohm. (Refer to NFPA-33,
EN 16985.)
Operators must be grounded. Rubber soled
insulating shoes should not be worn. Grounding
straps on wrists or legs may be used to assure
adequate ground contact.
Operators must not be wearing or carrying any
ungrounded metal objects.
When using an electrostatic handgun, operators
must assure contact with the handle of the applicator
via conductive gloves or gloves with the palm section
cut out.
NOTE: REFER TO NFPA-33, EN 16985 OR
SPECIFIC COUNTRY SAFETY CODES
REGARDING PROPER OPERATOR
GROUNDING.
All electrically conductive objects in the spray area,
with the exception of those objects required by the
process to be at high voltage, must be grounded.
Grounded conductive ooring must be provided in
the spray area.
Always turn off the power supply prior to ushing,
cleaning, or working on spray system equipment.
Unless specically approved for use in hazardous
locations, all electrical equipment must be located
outside Class I or II, Division 1 or 2 hazardous
areas, in accordance with NFPA-33.
Avoid installing an applicator into a uid system
where the solvent supply is ungrounded.
Do not touch the applicator electrode while it is
energized.

Tells how to avoid the hazard.
High voltage equipment is
utilized in the process. Arcing
in the vicinity of ammable or
combustible materials may
occur. Personnel are exposed
to high voltage during operation
and maintenance.
Protection against inadvertent
arcing that may cause a re or
explosion is lost if safety circuits
are disabled during operation.
Frequent power supply shut-
down indicates a problem in
the system which requires
correction.
An electrical arc can ignite
coating materials and cause a
re or explosion.
Unless specically approved for use in hazardous
locations, the power supply, control cabinet, and all
other electrical equipment must be located outside
Class I or II, Division 1 and 2 hazardous areas in
accordance with NFPA-33 and EN 16985.
Turn the power supply OFF before working on the
equipment.
Test only in areas free of ammable or combustible
material.
Testing may require high voltage to be on, but only
as instructed.
Production should never be done with the safety
circuits disabled.
Before turning the high voltage on, make sure no
objects are within the sparking distance.
Electrical Discharge
Electrical
Equipment
Certain materials may be
harmful if inhaled, or if there
is contact with the skin.
Follow the requirements of the Safety Data Sheet
supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the air
free of accumulations of toxic materials.
Use a mask or respirator whenever there is a chance
of inhaling sprayed materials. The mask must be
compatible with the material being sprayed and its
concentration. Equipment must be as prescribed
by an industrial hygienist or safety expert, and be
NIOSH approved.
Chemical HazardToxic Substances
Spray applicators require that aluminum inlet ttings
be replaced with stainless steel.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum
equipment during spraying, ushing, or cleaning.
Read the label or data sheet for the material you
intend to spray. If in doubt as to whether or not a
coating or cleaning material is compatible, contact
your coating supplier. Any other type of solvent may
be used with aluminum equipment.
Halogenated hydrocarbon
solvents for example:
methylene chloride and 1,1,1,
- Trichloroethane are not
chemically compatible with the
aluminum that might be used
in many system components.
The chemical reaction
caused by these solvents
reacting with aluminum can
become violent and lead to an
equipment explosion.

INTRODUCTION
GENERAL DESCRIPTION
The Ransburg Aerobell 268 is a high speed bell type
atomizer for electrostatic applications of conventional and
high solids coating materials. It is available in several
congurations. Contact your Ransburg representative for
assistance in atomizer bell selection.
The Aerobell 268 turbine assembly incorporates precision
air type bearings for extended turbine life.
FEATURES
Features which make the Aerobell 268 advantageous for
use in rotary atomizer electrostatic applications include:
•Fast color change due to center feed uid delivery and
integral air brake, integral solvent and air valves
•Sleek conguration to facilitate cleaning of
the exterior
•Braking air capability
•Field repairable turbine assembly after the warranty
period
•Machine mountable
•Non-hollow wrist robot mountable
•30mm dual shape air conguration for optimum
pattern control
•65mm Mono Flex and Dual Flex shaping air
conguration for optimum pattern control
•30 and 65mm Bell cups are electroless nickel coated
aluminum and titanium
•Proven long life air bearing spindle
Figure 1: Aerobell 268
•Speed control: This unit has exibility in speed
sensing capability. Both magnetic and light sensing for
speed reading and control can be utilized
•Internal and external bell cup wash capability
•Lightweight
•ATEX approved when properly congured.
•Power supply has di/dt function to shut down if current
of the system rises too quickly.
•Power supply may be controlled either locally or
remotely by PLC or other control feature.
•Congurable manifold for up to 3 individual colors or
materials, (Primer, Base, Clear) if compatible.
