Abstract

A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.
