Abstract
A fluid dispensing device includes an electrostatic discharge protection system. Accumulation and discharge of electrostatic energy created by operation of the device is reduced or prevented by the electrostatic discharge protection system without an earth ground connection. The electrostatic discharge protection system may include a number of features, such as a static wick, non-conductive components that electrically isolate the spray tip of the device, nonconductive isolation barriers, nonconductive fluid reservoir and suction tube components, a nonconductive coating of a control valve component, and a nonconductive spring retainer of the control valve.
