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.
