Short description
The spray gun is intended for surface
coating. Compressed air is used to apply
material. The coating material is fed through
lines. The operation can be done with paint
circulation or tap line.
Use a suitable nozzle set, depending on the
requirement.
Flat jet nozzle set: Generates round and
flat spray patterns (spray pattern width up
to 35 cm).
Round jet nozzle set: Generates round
spray patterns, marking painting and
painting with a directed fine jet. Suitable
for narrow surfaces (up to about 4 cm)
with very low over-spray component e.g.
for glass industry, over-painting of weld
and solder seams.
Rotary jet nozzle set: Generates round
spray pattern. Applies materials with a
very high viscosity (e.g. glue) with high
spraying air requirement. Coated parts
with difficult-to-access shapes and
recesses, for which the dense misting
creates a cover.
The following factors influence the spray jet
and therefore the result:
Alignment of the air cap (only if using a
flat jet nozzle set)
The alignment of the air cap determines
the alignment of the spray jet.
Atomizer air pressure
The higher the atomizer air pressure, the
higher the atomizing and the finer the
spray jet.
Horn air pressure (only if using a flat jet
nozzle set)
The higher the horn air pressure, the
more oval is the spray jet.
Control air pressure
Opens the needle and controls the mate-
rial outflow.
Material pressure
The higher the material pressure, the
higher the material flow.
Control air pressure is controlled externally
via valves.
If the horn air pressure and atomizer air
pressure are not controlled externally, they
can be adjusted on the horn air control (F)
and the atomizer air control (R). The
spraying air pressure (A) is controlled exter-
nally via valves.
You can also regulate the material flow via
the material flow control, if it is not controlled
