1.2 Short description
The spray gun is intended for surface
coating without compressed air. It is suitable
for Airless Applications in the high pressure
area. The material to be atomized is fed
through high pressure lines and atomized
with a pressure of up to 300 bar. The spray
gun is hand-held.
Use a nozzle with a suitable diameter,
depending on the requirement. If there is a
blockage, you can rotate and flush the
nozzle through without disassembly.
The following factors influence the spray jet
and therefore the result
Material pressure
The higher the material pressure, the
higher the material flow and thus the finer
the atomization. The lower the material
pressure, the higher is the efficiency and
the smaller is the overspray generated.
Nozzle
The larger the nozzle, the more material
comes out. The greater the angle, the
wider is the spray pattern.

safe operation
The following conditions must be observed
for safe operation with inflammable mate-
rials:
Ground spray gun and work piece.
Only use conductive hoses.
Ensure that static electricity can be dis-
charged.
2.3 Residual risks
Explosion
Sparks, open flames and hot surfaces can
cause explosions in explosive atmospheres.
Serious injuries and death can be the conse-
quence.
Before carrying out any work, ensure a
non-explosive atmosphere.
Do not use sources of ignition and open
light.
Do not smoke.
Ground the product.
Ground the work piece.
Only use conductive lines.
Flammable coating materials and their deter-
gents and cleaning agents can cause a fire
or an explosion.
Ensure that the flashpoint of the fluid is at
least 15 K above the ambient tempera-
ture.
Note explosion group of the fluid.
Follow safety data sheets.
Ensure that forced ventilation and fire
protection equipment are in operation.
Do not use any sources of ignition and
open light.
