Paint Gun Perfection Air Shape Change
|
Only the air pressure was altered in these photos. Notice the effect on the shape of the material leaving the gun. With the pressure set at 20 psi (top) the fan is well shaped and the amount of fluid is even in the 4- to 6-inch "sweet spot" range. By the time the air pressure is cranked up to 30 psi (bottom) the pattern is blowing apart and the fan has rounded into a swallowtail shape. The air pressure is blasting the fluid farther from the nozzle in the middle, but it's not even across the fan. View Related Article
