WAGNER expands its portfolio in the
automatic liquid coating sector
with a new, universally applicable
airspray gun
has an additional wear-resistant and low-friction coating. The optimised, particularly durable packing and
the specially coated needle support uninterrupted operation. "Even after one million switching operations,
there were no leaks in the field test. Accordingly, the number of maintenance operations is considerably
reduced. Thanks to the modular and service-friendly design, the wear and spare parts can then be replace
very quickly. This increases productivity and at the same time reduces maintenance and spare part costs,

The new automatic airspray
gun TOPFINISH GA 1030
for industrial liquid coating
convinces with excellent
atomizing properties and a
high-quality spray pattern.
The universal unit for
automatic applications is
particularly low-wear, which
reduces spare part costs and
halves maintenance costs.
This enables process-safe
coating in continuous operation.
The TOPFINISH GA 1030 from WAGNER
impresses with its high reliability, minimal
overspray and particularly low paint mist.
Due to its modular design, the automatic
airspray gun can be used for a wide variety
of applications for coating work pieces made
of wood, metal or plastic where a perfect
appearance with high-quality surfaces is
essential. “Thanks to a particularly large
material passage of the nozzle, water and
solvent-based media can be applied just as
easily as low to high viscosity materials and
paints with a high solids content. Especially
for coating with UV and highly abrasive
materials, the automatic gun is available
as TOPFINISH GA 1020 version with
membrane seal - for switching times of less
than 20 milliseconds and particularly fast
position changes in the coating process,”
explains Peter Neu, Senior Product Manager
Industrial Solutions at WAGNER.
Modular design for all
coating requirements
The new gun can be converted into different
variants in no time at all. Several air caps
and nozzles are available for applying
different paints. In order to keep storage and
investment costs low, these and the needles

are identical to the spare parts of the manual
TOPFINISH airspray gun GM 1030P. The
TOPFINISH GA 1030 can optionally be
supplied with several circulation variants, with
and without flushing valve and with various
base plates. Optional rear or side connections
support optimal movement. Several adapters
are available depending on the type of
mounting required and for robot mounting.
In addition, there is a robot version with fixed
needle stroke without air valves.
Efficient material use
Overspray and thus material consumption are
minimised by the optimised design of the air
duct. This allows a transfer efficiency of up
to 85 percent to be achieved. The material
flow is regulated very precisely via a needle
adjustment knob with micrometer screw.
The gun is available with internal and external
air regulation, via buttons on the gun or
remote control. No matter which version of
the TOPFINISH GA 1030 a user chooses:
For a reliable coating process, the air supply
to all variants of the new airspray gun is
automatically interrupted during the coating
process as soon as the needle closes.
Long maintenance intervals
and low spare part costs
Just like the manual TOPFINISH GM 1030P,
the automatic TOPFINISH GA 1030 is
equipped with a two part nozzle consisting
of nozzle head and nozzle nut, saving costs.
In case of wear, only the nozzle head has
to be replaced. All parts in contact with the
material are made of durable stainless steel
and the needle has an additional wear-
resistant and low-friction coating. The
optimised, particularly durable packing
and the specially coated needle support
uninterrupted operation. “Even after one
million switching operations, there were
no leaks in the field test. Accordingly, the
number of maintenance operations is
