The Tribomatic 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 gun is used with a
Tribomatic Magnum control unit.
See Figure 1. The gun consists of a chargetube (4), diffuser (1), and a
spacer (5). The gun mount (3) is used to mount the gun to a reciprocator,
oscillator, or a fixed gun stand.

Flow-rate air pumps powder out of the feed hopper and forces it through
the feed hose into the diffuser. Diffuser air mixes with the powder and
increases its speed. The powder and air mixture then passes through a
group of spiral tubes inside the chargetube. The collision of the powder
particles with the walls of the tubes electrostatically charges both the
powder particles and the tubes’ inner surface.
