Electrostatic spray guns
Electrostatic spray guns have a high voltage difference of 40,000 to 85,000 volts depending on the model, between the spraygun and the work being sprayed; this charges the paint particles leaving the spraygun, attracting them strongly to the work, encircling it and drawing the particles to surfaces not directly visible from the spraygun, ensuring a good coating of them all. Electrostatic spray will not penetrate holes, which cause a charge free zone because of the Faraday cage effect. The strong attraction of the paint particles almost eliminates any overspray, so electrostatic spray is also often in situations where spraying would not otherwise be allowed. Electrostatic spray cannot be used in anything other than a very light wind, depending on the spraygun model, so is mainly used in inside situations, but a temporary enclosure can be used to shield it from the elements, eg when spraying railings and gates. The electrostatic voltage is often generated by an external unit with a high voltage cable connected to the spraygun; one manufacturer Graco has the voltage generator built into the spraygun.
Graco Pro Xp electrostatic sprayguns
Graco Pro Xp electrostatic spray guns are air-assisted airless (AA) sprayguns with the high voltage generator built into the spraygun, eliminating the need for a high voltage cable to it and reducing the effective weight of the gun. Three of them are low material pressure sprayguns up to 7 bar (100 psi), so not strictly AA, and two are full airless material pressures up to 210 bar (3,000 psi). Smart controls with an LED display are available for the 60kV and 85kV models.
There are several different Graco xP electrostatic spray gun to suit different equipment and work, so please call us for more information
