Spray areas must be kept clean to prevent the

accumulation of combustible residues.

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

at all times.

Test only in areas free of combustible material.

Testing may require high voltage to be on, but only

as instructed.

Non-factory replacement parts or unauthorized

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.

AREA

Tells where hazards

may occur.

HAZARD

Tells what the hazard is.

SAFEGUARDS

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.
