Section 2
Description
Introduction
The Tribomatic II purgeable automatic powder spray gun uses friction (the
tribo effect) to electrostatically charge powder coating particles as they are
forced through the gun by compressed air. The spray gun is used with a
Tribomatic II controller and powder pump.
See Figure 2-1. The spray gun consists of a charge module (3), diffuser (1),
in-line ball mount (2), and various optional sprayheads (4). The charge
module and diffuser are threaded into the body so that all parts stay
together under purge air pressure.
The gun mount is used with a 5/8-in. diameter mounting bar to mount the
spray gun to either a gun mover or fixed gun stand. The spray gun uses the
same wide variety of optional nozzles and sprayheads available for use with
the original Tribomatic automatic spray gun. Options are listed in Table 2-1.

Description

Part 1014255A02 E2003 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 sleeves electrostatically charges both the
powder particles and the sleeves.
The 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 depends on many factors,
including the powder type and its speed through the spray gun.
Options
The options listed in Table 2-1 are available for use with the Tribomatic II
purgeable automatic spray gun. Unless other wise noted, refer to Options

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.
Introduction
Each automatic spray gun is controlled by a spray gun control unit that
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.
Purging is controlled through either the spray gun control unit or powder
feed center. Refer to your controller or feed center manual for more
information.
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.
Daily Operation
Table 4-1 Operating Recommendations
Operating
Parameter
Recommendation
Air
Pressure
Settings
Powder volume, velocity, and atomization are controlled by the flow rate and diffuser air
pressure settings. As a starting point, set air pressures to
SFlow rate (ejector) 1.8 bar (26 psi)
SDiffuser (atomizing) 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.
Part
Hangers
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 as practical to the minimum required by law without compromising safety.
Sprayheads 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.

Operation
4-2
Part 1014255A02 E2003 Nordson Corporation
Maintenance
When used with a powder feed center, the spray gun will be internally
purged when you perform the powder feed center color change and
maintenance procedures. Refer to your powder feed center manual for
more information.
Perform the following procedure periodically.
WARNING: Make sure the spray gun is grounded before cleaning it with
compressed air or spraying powder. 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 compressed air from an OSHA-approved air
gun to clean the hose, diffuser, and charge module.
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.
CAUTION: 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.
2. Remove the diffuser from the gun body. 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. Blow out the charge module and sprayheads. Disassemble and clean
the charge module. Check the powder contact parts for wear and
replace worn parts.
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.
4. 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 .
