Description
Introduction
The Nordson extended Tribomatic II automatic powder spray gun uses
friction (the tribo effect) to electrostatically charge powder coating particles
as compressed air forces them through the spray gun. The spray gun is
used with a Tribomatic II controller and powder pump.
See Figure 2-1. The spray gun consists of a diffuser (1), extension (2),
charge module (3), and various optional sprayheads (4). The standard
spray gun has a PTFE charge module for use with organic powder coatings.
The spray gun mounts to a reciprocator or oscillator, or to a fixed gun stand.
An optional gun holder adapter allows existing Tribomatic gun holders to be
used with gun mounting bars.
The spray gun uses the same wide variety of optional nozzles and
sprayheads available for use with the original Tribomatic automatic powder
spray gun. Options are listed in Table 2-1.
Table 2-2 lists the characteristics of the PTFE and Tivar materials used in
the Tribomatic II powder spray guns. Use this table to identify the materials
used in your spray gun.

Part 334691B03 E2006 Nordson Corporation
Operation
Flow rate air pumps powder out of the feed hopper and forces it through the
feed hose to the diffuser. Diffuser air mixes with the powder and increases
its speed. The powder and air mixture then passes between the inner and
outer wear sleeves inside the charge module. The collision of the powder
particles with the walls of the wear sleeves electrostatically charges both the
powder particles and the wear sleeves.
The wear sleeves are grounded through the gun body, ground wire, and
control unit. The charge picked up by the sleeves is displayed in
microamperes at the control unit. The display indicates how well the
powder is charging. The higher the number, the stronger the charge the
powder is receiving. The strength of the charge the powder receives will
vary depending on many factors, including the powder type and its speed
through the spray gun.
Options
Table 2-1 lists the options are available for the extended Tribomatic II
automatic powder spray gun. Unless otherwise noted, refer to Options on
page 7-9 in the Parts section for part numbers and ordering information.

Section 4
Operation
WARNING: Allow only qualified personnel to perform the following tasks.
Follow the safety instructions in this document and all other related
documentation.
WARNING: All electrically conductive equipment in the spray area must be
grounded. Ungrounded or poorly grounded equipment can store an
electrostatic charge which can give personnel a severe shock or arc and
cause a fire or explosion.
WARNING: Make sure the spray gun is grounded before spraying powder
or cleaning the spray gun with compressed air. Without a ground
connection the spray gun will become electrostatically charged. Personnel
touching the spray gun could receive a shock.
Introduction
Each automatic powder spray gun is controlled by one gun control unit
which houses electrical controls, a digital display, and regulators and
gauges for flow rate and diffuser air. Refer to the control unit manual for
operation instructions.
Operation
Powder volume, velocity, and atomization are controlled by the flow rate and
diffuser air pressure settings. As a starting point, set air pressures to
Flow rate (ejector) air pressure 1.8 bar (26 psi)
Diffuser (atomizing) air pressure 2.5 bar (36 psi)
Keep the flow rate air pressure as low as possible. Maintain the same ratio
of diffuser air-to-flow rate air without reducing the charging level. Reduce
the diffuser air pressure if powder is being blown out of recesses. Build
coating thicknesses slowly. Reduce air pressures to keep overspray to a
minimum.
Experiment with the part hanger configuration and part density. Reduce the
space between parts to keep overspray to a minimum. Keep the air velocity
through the booth as close to the minimum required by law as practical
without violating safety.

Operation
4-2
Part 334691B03 E2006 Nordson Corporation
Operation (contd)
Use different sprayheads for different part shapes. Select the appropriate
nozzle for the parts being coated:
SPinpoint nozzles for penetration
SEight-orifice nozzles for flat surfaces
SCylindrical nozzles for general purpose coating
Angle the nozzles to meet and follow the parts as they move through the
booth. Typical nozzle-to-part distance is 20−25 cm (8−10 in.). Coat the
inside surfaces and recessed areas first, then coat the outside surfaces and
open areas.
Daily Maintenance
WARNING: Make sure the spray gun is grounded before spraying powder
or cleaning the spray gun with compressed air. Without a ground
connection the spray gun will become electrostatically charged. Personnel
touching the spray gun could receive a shock.
1. Remove the powder feed hose from the pump and the air tubing from
the pump and diffuser. Use an OSHA-approved air gun to clean the
hose, diffuser, and charge module with compressed air.
NOTE: Never blow powder through the feed hose back into the pump.
Turn on the booth exhaust fan, disconnect the hose from the pump, and
blow out the hose from the pump end into the booth.
2. Remove the diffuser from the extension. Disassemble the diffuser and
clean the parts with compressed air and a clean, soft cloth. Check the
powder contact parts for wear and replace worn parts.
3. Remove the rear connector and blow out the gun body.
4. Blow out the extension, charge module, and sprayhead.
5. Disassemble and clean the charge module. Check the powder contact
parts for wear and replace worn parts.
NOTE: Never use a knife or other sharp object to clean plastic parts.
Powder will build up on scratches on the powder contact surfaces. The
powder particles can fuse on impact and clog the spray gun.
WARNING: All electrically conductive equipment in the spray area must be
grounded. Ungrounded or poorly grounded equipment can store an
electrostatic charge which can give personnel a severe shock or arc and
cause a fire or explosion.
6. Make sure all conductive equipment in the spray area, including the
spray guns, are connected to a true earth ground. The resistance from
part to ground, through the hangers and conveyor, must not exceed
one megohm. For best results, the resistance should be less than
500 ohms.
