ABSTRACT:
Electrostatic spray guns are connected in series to a pressurized source of liquid spray material. Each gun has an attached pressure regulator for evening the pressure of liquid supplied to the gun and the consequent spray pattern emitted from the gun. Each regulator is so constructed that it minimizes the pressure drop of liquid passing through the regulator to the next series connected regulator. Additionally, each regulator is made primarily from a low capacitance plastic material so that it cannot store and discharge an electrical potential sufficient to create a dangerous condition in a spray environment. Each regulator is so constructed that it may be manually adjusted to vary the pressure of liquid supplied from the regulator to the attached gun or may be easily converted to pneumatic control.
