THE RANSBURG ELECTROSTATIC

PROCESS

This process is a method for electrostatically applying

coatings to objects. A power supply produces a high

voltage charge which is supplied to the applicator,

creating an electrostatic field between the applicator

and the target object. The target is electrostatically

grounded through its support which may be either

stationary or moving.

A regulated fluid system delivers coating material to

the applicator, where it is atomized forming a spray

mist. There, under the influence of the electrostatic

field, the atomized coating becomes electrostati-

cally charged. The charged particles are attracted to

and deposited on the grounded target object. The

forces between the charged particles and the target

are sufficient to turn overspray around and deposit it

on the back surface of the target. Therefore, a higher

percentage of the spray is deposited.

Evolver 303 Dual Purge Robotic Atomizers - Introduction

EVOLVER™ 303 DUAL PURGE

SOLVENTBORNE SPRAY

APPLICATORS

The Evolver

303

Dual Purge Spray Appli-cators System

will allow for the use of spray applicators or bell ap-

plicators with minimal required down-time during

the switching process. This system can also operate

as a spray applicator system only that later can be

upgraded to allow for bell applicators having "Unilink

Technology"to be used. This system can allow a user

currently possessing an RMA-303 bell system to use

spray applicators as well, with minimal conversion

required. Lastly, this system is a true dual purge

system in that paint can be sprayed with full voltage

on, while simultaneously color changing the second

paint line. The Evolver 303

Dual Purge Solventborne

Applicator line consists of both 60

° and 90° single

and dual-headed 100kV automatic electrostatic ap-

plicators. Developed for use on robot, the Evolver

303 Dual Purge spray applicator incorporates a

unique 1/3 turn quick-disconnect spray head and a

one piece slide over manifold cover, providing the

user an efficient tool for the electrostatic application

of coatings.

There are two single-head models of the Evolver 303

Dual Purge Applicators (see Figure 1). Each model

differs in the applicator to axis orientation of the spray

head. These models are:

A12374-0XX 60

° Single-Head

A12374-1XX 90

° Single-Head

Two dual-head versions of the Evolver 303 Dual Purge

Applicator are also available (see Figure 1). The dual-

headed applicators are primarily used where high

volume fluid delivery is required. The dual-headed

applicator is available in two different configurations

as follows:

A12374-2XX 60

° Dual-Head

A12374-3XX 90

° Dual-Head
