Overview

Overview

Usage

The Graco ProMix 2KS 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 to 50:1 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 or
air-assisted systems with a capacity of up to 3800
cc/min.

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.
