Abstract: A system including an electrostatic tool including a handle, a first trigger configured to move between a first trigger position and a second trigger position, wherein the electrostatic tool is configured to be inactive when the first trigger is in the first trigger position and to spray a coating material when the first trigger is in the second trigger position, an electrostatic activation system configured to activate and deactivate electrical charging of the coating material, and wherein the first trigger and the electrostatics activation system may be separately and simultaneously engaged with a single hand.

Abstract: A system includes an air cap configured to mount to a head of a spray device, wherein the air cap comprises at least one air passage having a curved flow path. A system may include a spray head having a first curved air passage that turns inwardly toward a central axis of the spray head, and a second curved air passage that turns inwardly toward the central axis of the spray head, wherein the first and second curved air passage are configured to direct first and second air flows inwardly toward a spray to shape the spray. A system may include a spray device having a liquid passage leading to a liquid outlet, and a curved air passage that gradually curves toward an air outlet.

Abstract: A system includes an electrostatic tool having a turbine generator to generate electrical power for charging an electrostatic spray. The electrostatic tool also includes a compressed air shutoff unit that automatically blocks flow of air to the turbine generator based on a sensed inactivity of the electrostatic tool.

Abstract: In accordance with one embodiment a system is provided that includes an aerosol spray can, a receiver configured to electrically insulate the commercially available aerosol spray can, and a nozzle headpiece configured to couple to a neck portion of the aerosol spray can. Further, the nozzle headpiece is configured to electrostatically charge the aerosol spray can, and the nozzle headpiece includes an electrostatically charged passage.

Abstract: A system, in certain embodiments, includes a spray device including a frame having a receptacle configured to receive a self-contained spray can. The spray device further includes a first conductive element configured to contact the self-contained spray can, and a first electrical conductor extending between the first conductive element and an earth ground such that a first electrical potential of the self-contained spray can is substantially equal to a second electrical potential of the earth ground while the self-contained spray can is in contact with the first conductive element. The spray device also includes a corona-charging electrode positioned adjacent to a spray nozzle of the self-contained spray can. The corona-charging electrode is configured to emit a stream of ions toward the self-contained spray can such that a spray of fluid from the spray nozzle passes through the stream of ions and becomes electrostatically charged.
