The AcuKote HVAF gun generates a large jet, about 3/4-inch in diameter, with shock "diamonds" visible at 10-12 inches off the nozzle - a distance far greater than the usual stand-off distance during spraying (5-7 inches). In spite of such "powerful" appearance, the gaseous jet does not heavily heat a coated work piece, since combustion is practically completed in the chamber, and no afterburning occurs in the jet itself.

The diameter of a spray powder jet does not exceed 1/4-inch, i.e., the spray powder is well enveloped by the gaseous jet along the entire spray distance, providing good protection against the in-flight oxidation of the spray material. This concentrated powder jet has evident advantages in spraying small-target parts as well as hard-to-reach areas and confined spaces. However, it requires robotic or automated applications to provide an even coating thickness.
