Overview
Usage
The Graco ProMix™ II is an electronic two-component paint proportioner. It can blend most two-component solvent
and waterborne epoxy, polyurethane, and acid-catalyzed paints. It is not for use with “quick-setting” paints (those with
a potlife of less than 15 minutes).
•
Can proportion at ratios from 0.1:1–30:1 in 0.1
increments.
•
Has user selectable ratio assurance and can main-
tain up to +/-1% accuracy, depending on materials
and operating conditions.
•
Models are available to operate air spray,
air-assisted, or airless systems with a capacity of up
to 3800 cc/min.
•
Color change options are available for low pressure
(300 psi [2.1 MPa, 21 bar]) air spray and high pres-
sure (3000 psi [21 MPa, 207 bar]) systems with 2, 4,
or 6 color change valves.
•
Gun Flush Box option is also available.
Component Identification and Definition
. 1 for the ProMix™ II system components.
Component
Description
EasyKey™ Display
Used to set up, display, operate, and monitor the ProMix™ II system. The EasyKey™
Display accepts 85-250 VAC, 50/60 Hz line power and converts that power to accept-
able low voltage and optical signals used by other system components.
Smart Fluid Panel
Includes air control solenoids, pressure and flow switches, fluid flow meters, and the
fluid manifold assembly to control and monitor fluid dispensing.
Fluid Manifold
Fluid component assembly mounted on the Smart Fluid Panel. It includes:
•
Pneumatically Operated Dispense Valves for component A and B
•
Purge Valves for solvent and air purge
•
Sampling Valves for calibrating the flow meters
•
Shutoff Valves for component A and B to close their fluid passages to the mix
manifold
•
Mix Manifold, which includes the fluid integrator and static mixer.
➜
Fluid Integrator is the chamber where component A and B align at the
selected ratio and begin to mix.
➜
Static Mixer has 24 elements to uniformly blend the materials downstream of
the fluid integrator.
Color Change Valves
An optional component of the Fluid Manifold assembly. It is available as a color
change valve stack for either low or high pressure with 2, 4, or 6 color change valves.
Each stack includes one additional valve for solvent to clean the fluid line between
color changes.
