OTSON’s manual liquid electrostatic spray gun OTS-3000+G7 is a versatile and efficient way to apply coatings and lacquers. The gun utilizes air or high pressure to atomize the coating material and can be fitted with different air nozzles and caps to create different spiral spray patterns.

Key features:

  • Model number: OTS-3000+G7
  • Charged atomization: The coating material is atomized and given a negative charge, allowing the negatively charged droplets to be attracted to any earthed surface. This results in high transfer efficiency of up to 95% and minimized overspray.
  • Versatility: OTSON’s electrostatic technology can be used with waterborne paints, solvent paints, and lacquers.
  • Efficient atomization: The spiral effect created by the spray gun reduces the velocity of the lacquer particles, leading to efficient atomization of the coating material. This results in a smooth, even finish with no runs or drips.
  • Powerful attraction: The electrostatic attraction is so strong that in some cases, the coating spray can be observed to “wrap around” the object, providing complete coverage and preventing gaps or missed spots.
  • Longstanding expertise: With over 30 years of experience in research and development of electrostatic equipment, OTSON is a trusted and reliable brand in the industry.


  • High transfer efficiency: Up to 95% of the coating material is applied to the surface, resulting in less waste and a more cost-effective process.
  • Minimized overspray: The negative charge of the coating material helps to attract it to the surface, preventing overspray and reducing environmental impact.
  • Smooth, even finish: The spiral effect of the spray gun ensures a smooth, even finish with no runs or drips.
  • Complete coverage: The powerful electrostatic attraction provides complete coverage, even on complex shapes and surfaces.
  • Reliable and durable: OTSON’s manual liquid electrostatic spray guns are built to last, with a long lifespan and high performance.
Electrostatic Effect

Conventional spray guns charge the liquid droplets only by the movement of the liquid through the nozzle, and any charge that might be generated during the process is negligible. OTSON’s OTS-3000+G7 Manual Liquid Electrostatic Spray Gun, on the other hand, applies an electric charge to the liquid droplets as they are ejected from the nozzle. This is done by charging the paint or coating material to a high voltage.

The electrostatic effect causes the charged particles to be attracted to an earthed object, such as a car body or a piece of furniture. This results in a more efficient, precise, and consistent application of paint or coating material. The electrostatic attraction between the charged particles and the earthed object overcomes any natural tendency of the droplets to disperse or deflect, resulting in a highly controlled, even application.

The electrostatic effect also reduces overspray and bounce-back, which reduces waste and cleanup time. Overall, the electrostatic effect of the OTSON OTS-3000+G7 Manual Liquid Electrostatic Spray Gun produces a high-quality finish.

Here are some additional benefits of using the OTSON OTS-3000+G7 Manual Liquid Electrostatic Spray Gun:

  • It can be used to apply paint or coating material to a wider variety of surfaces, including those that are difficult to reach with a conventional spray gun.
  • It can be used to apply paint or coating material in a more environmentally friendly way, as it reduces the amount of overspray and waste.
  • It can be used to apply paint or coating material more quickly and efficiently, which can save time and money.

If you are looking for a way to apply paint or coating material more efficiently, precisely, and consistently, then the OTSON OTS-3000+G7 Manual Liquid Electrostatic Spray Gun is a good option to consider.
