Tells what the hazard is.
Fire Hazard
Improper or inadequate
operation and maintenance
procedures will cause a re
hazard.
Protection against inadvertent
arcing that is capable of causing

Tells how to avoid the hazard.
Fire extinguishing equipment must be present in the
spray area and tested periodically.
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.
When using solvents for cleaning:
• Those used for equipment ushing should have ash
points equal to or higher than those of the coating
material.
• The ash point of the cleaning solvent shall be at
least 15° C (27° F) above the ambient temperature.
Otherwise, the cleaning process must be carried
out in an area with forced air ventilation. It is the end
users responsibility to insure this condition is met.
Spray booth ventilation must be kept at the rates
required by NFPA-33, OSHA, 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
equipment modications may cause re or injury.
If used, the key switch bypass is intended for use only
during setup operations. Production should never be done
with safety interlocks disabled.

Certain material may be harmful
if inhaled, or if there is contact
with the skin.
Explosion Hazard –
Incompatible Materials
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.
Follow the requirements of the Material 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.
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.

ATEX REQUIREMENTS
Atex Requirements
This product provides an direct charge to water
based materials that will improve the transfer
efficiency over non-electrostatic products.
Because this product uses water based materials
only, there may be no requirement for an Atex
approval except for the hose test. As long as
the material being used meets the ammability
denition as stated in EN 50 059: 1991**, there
is no hazardous area that must be zoned around
the applicator. No Atex approval is required. It is
the end users responsibility to insure all of these
conditions are met.
FM REQUIREMENTS
Requirements
**EN 50 059: 1991 Denition of
non-ammable spraying material

hand held spraying equipment and which cannot
be ignited, when in any mixture with air, by an
energy source less than 500 mJ.
When this product is installed in a system, the
maximum discharge energy must be less than
350 mJ. (EN 50 059: 1990)
These applicators are FM approved when the
product setup is congured to drawings shown on
page 8. This product is approved for use only with
non-ammable water based materials when the
materials meet the FM denition for a water based
spray material*. It is the end users’ responsibility
to insure the material that is sprayed meets this
requirement.
* FM 7260 water based spray material - a material

The RansFlex is an air atomizing applicator powered
only by a pressurized air source. Pressurized air creates
rotation of a turbine generator that powers a cascade.
The cascade generates a high voltage DC charge to
the electrode creating an electrostatic eld between
the atomizer and the target.
One of the many features of the RansFlex applicator
system is that the electrical energy, which is available
from the resistive charging electrode, is limited to the
optimum level of safety and efciency. The system is
incapable of releasing sufcient electrical or thermal
energy during normal operating conditions to cause
ignition of specic hazardous materials in their most
easily ignited concentrations in air.
As the applicator electrode approaches ground,
applicator circuitry causes the high voltage to approach
zero while the current approaches its maximum value.
This performance is validated by independent test
agencies that give ATEX EN 50 050 approvals of FM
7260 approvals.
RANSFLEX NEW FEATURES
• Light weight and easy to maneuver.
• Ergonomic handle design to reduce
operator fatigue.
• Three phases of turbine protection:
- Divorced turbine air supply cartridge
- Sealed nozzle/Atomization passages
- Strategic turbine location
• DeVilbiss spray technology integration
into atomization.
This RansFlex model is designed specically for direct
charge water base applications only. The design requires
the need for isolation equipment normally needed for
use with electrostatic waterborne applications.
The water base materials must be classied as nonamable spray material. This means the mixture with air
cannot be ignited by an energy source less than 500 mJ.
Operating Voltage: 65kV DC (-) maximum
Current Output: 120 microamperes maximum
Paint Resistance:* Water base paint only

For proper safe function of the applicator, the
79727-XX or 80558-XX Air Hose Assembly must be
used
(either standard or quick disconnect style).
Filters
1. Install an air lter assembly on the outlet of the
main air regulator. The lter should be 5 micron
with a maximum working pressure of at least 100
psig (6.9 bar). For Class 3 air quality, which is a 5
micron size and has a dew point of -4°F (-20°C),
the relative humidity (RH) of the air should be 5%.
2.
Ransburg recommends that a uid lter be installed
at the output of the uid supply (pressure pot,
pump, circulating system, etc.). It is the end user's
responsibility to install the proper lter that meets
their system's requirements.
