Description
The Promaks Tribo PTAG07 automatic powder spray gun uses friction
(the tribo effect) to electrostatically charge powder coating particles as they
are forced through the spray gun by compressed air. The spray gun is used
with a PTAU07 controller and powder pump.
The gun mount is used with a
/
-in. diameter mounting bar to mount the
5
8
spray gun to a reciprocator or oscillator, or to a fixed gun stand. An optional
gun holder adapter allows existing PTAG07 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 PTAG07 automatic spray
gun
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.
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 spray 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.
