1.2 Short description
The spray gun is using compressed air to
coat surfaces. The coating material is fed
through lines.
The following factors influence the spray jet
and the result:
nAlignment of the air cap
The alignment of the air cap determines
the alignment of the spray pattern.
nAtomizer air pressure
The higher the atomizer air pressure, the
higher the atomizing and the finer the
spray jet
nHorn air pressure
The higher the horn air pressure, the
more oval is the spray jet.
nControl air pressure
Opens the needle and controls the mate-
rial flow.
nMaterial pressure
Product overview
06/2023EcoGun AS AUTO Mini FS - MSG00006EN4/36

The higher the material pressure, the
higher is the material flow.
Control air pressures and the atomizer air
pressure are controlled externally via valves.
You can set the horn air pressure on the
spray gun. If you attach a connection for
external jet control instead of the horn air
regulation Ä 11.3 “Accessories”, you can
control the horn air pressure via an external
valve.
You can also regulate the material flow via
the regulator on the spray gun, if it is not to
be controlled externally.
