Airmix® Review
Airmix® is different from Air Assisted Airless by
the method of incorporating the air into the fluid
p
pattern.
With Airmix®, the air is injected
before the p
point of atomization, it
results in a very stable fan and a
perfectly even film build.
With Air Assisted Airless systems,
the air is injected
j
into or beyond
y
the
point of atomization. It creates
turbulent air flows, more over spray
and reduced finish quality
quality.

Airmix® Review
Paint velocityy has a direct impact
p
on p
performance.
When the velocity is high, the over spray and bounce back is
increased. The result is lower transfer efficiency and a more
polluted environment
environment.
The particle speed with Airmix® is much lower than with other
atomization technologies

Airmix® Evolution
Kremlin is well known for being
g the leader in Airmix®
technology. The new Xcite™ gun is the result of years
of market research and product development.

New Features of XciteTM
Performance Improvements
New VX24 (HVLP) air cap - 132.720.020:
New Airmix® air cap for superior finish quality.
Choice of Fine or Xtra™ fine fluid tips for superior
finish.
Anodized aluminum air cap : compatible with water
based products.
86%
The best nonnon-electrostatic manual spray gun transfer efficiency!!
5
New fan reduction symbol
New fan width adjustment
The adjustment of the fan width
has been improved
2 ¼ turn knob instead of the ¾
turn knob on the MVX.
What is the improvement?
It allows for a finer fan
j
adjustment.
Paint savings
Width of the fan is adjusted to
fit the parts to be painted.
Time savings
No need to change the tip to
adjust the pattern size.
6
New fan width adjustment
The reduction of the fan width is more effective.
From 9.4” to 5.1” (24 -13 cm) at 1,015 psi (70 bar)
5% more effective than the MVX gun.

Why Buy the XciteTM Gun?
Highest finish quality
Airmix® creates a uniform pattern whereas Air Assisted Airless has a turbulent uneven
pattern.
Highest transfer efficiency
Airmix® has a lower p
particle velocity
y and less turbulence than other spray
p y
technologies.
Lowest energy consumption
With Airmix® less air is needed, just 1.7 CFM, than with other spray technologies.
Hi h application
li ti efficiency
ffi i
Higher
With Airmix® more coating can be applied without defects than with other spray
technologies.
Ergonomic design
The XciteTM gun is optimally balanced, less weight, and with a more comfortable feel,
leading to less spray operator fatigue.
Delivers extremely fast payback
With more material being applied to the part, using less air, have less to clean up, and
lower solvent emissions, the XciteTM gun will pay for itself.
