Conventional vs Electrostatic Paint Spray Guns - Graco Inc.

The Faraday cage effect can happen when spraying into corners or recessed areas with an electrostatic gun. Since charged paint spray is attracted to the grounded area closest to the applicator, the paint coats the part’s edges instead of going into the recessed area.

To compensate for the Faraday cage effect:

• Some painters use a conventional gun to coat the recessed area and then use electrostatics to finish the rest of the part.
• Others reduce or turn off the voltage of their electrostatic applicators and increase the air pressure, allowing shaping air to direct the paint into the corner.

If you’re here, we understand that you are ready to tackle a painting project but selecting the right spray painting gun may feel a bit overwhelming. Manual or Automatic Paint Guns – which is the ideal choice? 

Both get the job done, but they cater to different needs and skill levels. In this blog, we will do a side by side comparison of Manual and Automatic spray guns to help you pick the perfect partner for your painting project.

Working: 

• Manual Paint Gun: A manual paint gun is based on an external air compressor to create pressurized air. You pull the trigger, and the air mixes with paint in the gun, propelling it out of the nozzle and onto your surface. By adjusting the air strain and spray tip, you control the flow, pattern size, and finish of the paint.
• Automatic Paint Gun: An automatic paint gun also makes use of compressed air, however the paint feed is automated. An electric motor or compressed air powers the system to eliminate the need for you to constantly pull the trigger. This allows for faster application and less arm fatigue.

Choosing the Right Paint Spraying Gun:

• Manual Paint Guns: For small projects, detailed work, or if you’re a beginner, a manual paint gun is a great choice. It offers affordability, control, and is perfect for learning the ropes.
• Automatic Paint Guns: For large areas, high-production environments, or if speed and efficiency are your priorities, automatic paint guns are the way to go. They excel in consistent finishes and minimise fatigue.

No matter your choice, Patvin Engineering offers a variety of high-quality manual paint guns as well as automatic paint guns from trusted brands such as Graco, DevilBliss, Ransburg, and more.
