Vector Solo AA90 Applicators - Operation
Ransburg
20 AH-08-04.2
† Ransburg recommends the use of a fluid
filter in addition to the filter in the applicator
fluid line to reduce nozzle clogging.
PREPARATION
Paint
A selection of the proper paint mixture is essential
to electrostatic operation. Paint test equipment
may be obtained through your Ransburg repre-
sentative. For further paint formulation and test
procedures, consult your Ransburg representative
and/or your paint supplier.
Fluid Nozzle
Because of the design of the AA90 applicators,
the fluid nozzle precision is paramount to proper
function. Ransburg makes every effort to assure
that all production of this part will meet the critical
design standards necessary for all applications.
The selection of the best nozzle to apply a given
coating to a specific article with maximum effi-
ciency is not an exact science. Testing is usually
necessary and wide experience with many types
of coating applications helps. Your Ransburg
representative uses such experience and actual
laboratory testing when recommending a nozzle
for your application needs.
However, if parts, paints, or conveyor speeds are
changed, a different nozzle may be required for
best results. The following discussion and guide

will assist the user in making their own nozzle
selection whenever it becomes necessary. Se-
lection should always be verified by actual tests
to determine optimum efficiencies.
Refer to "Nozzle Selction Guide" in this section for
the choice of spray width and spray characteristics
appropriate to the size and type of target. The
maximum nozzle flow capacity depends on the
orifice size, the fluid pressure, the paint viscosity,
and the spraying temperature. Always remember,
for maximum paint economy any nozzle selected
should always be operated at the lowest fluid
pressure, which will give good atomization and
the required flow rate.
