Mixing Module
All gun models employ the concept of impinge-
ment mixing through the use of a single-part
MIXING MODULE. This system is cleaned by
a mechanical self-cleaning process, eliminat-
ing the need for solvent or air purging between
dispenses.
The gun can be assembled with two styles of
mixing components; their selection is depen-
dent upon the type of system sprayed. The
Set-Up Charts on pages 44 and 46 show sev-
eral of the more common sets of these config-
urations.
The Mixing Module, in combination with a Pat-
tern Control Disc (PCD), produce a thoroughly
mixed chemical and reliable spray patterns.
The module can be set up to spray at its maxi-
mum rated output. Additionally, by changing to
a smaller PCD the module can spray at the low
outputs and pressures that are required for
detail work.
