How Does a Pressure Feed Spray Gun Work?


pressure pot feed spray gun

The spray gun is charged as well as the droplets of paint. Given the same charge, they repel each other and produce a fine spray.

The part you are spraying on is typically the opposite charge and therefore the droplets of paint attract to the body part. This produces an even coat with little waste.

In terms of electrons, the paint gun loses its electrons and becomes positively charged. The droplets of paint lose electrons too and also become positively charged.

The object to be painted gains electrons and become negatively charged. The paint gun and droplets repel each other whilst the droplets and the object to be painted are attracted to each other.


What Paint Jobs Are Pressure Feed Sprayers Good For?


A pressure pot feed spray gun is great for applying latex paints, stains, sealers, top coats, long life epoxies, zincs, and lacquers to wood or steel. It is particularly great for spraying and touching up cars.

The paint lasts longer and it will always look better than other types of spray guns.

A Honda Civic was painted in just under 70 minutes with no paint sanding necessary.

The key is in the preparation. Rust was removed a day before from the car, and body filler applied.

The entire car was sanded and a primer was used to perfect it. This took longer than the painting itself, but the preparation allowed this to happen.

It is also advised to practice your HLVP spraying technique before committing to a project. Practicing on a vertical surface and a horizontal surface first will make sure you can spray evenly without leaving a drip.

Buyers Guide To Pressure Pot
Feed Spray Guns


Buyers Guide To Pressure Pot Feed Spray Guns

Pressure pot feed spray guns are the best types of spray guns to control the paint. Due to the fluid and air pressure being controlled separately, you have the ability to produce smooth finishes to your project.

In addition, if a coating is viscous, you simply increase the pressure of the paint and you’ll be good to go.

Majority of the paint spray guns are HLVP and so require 2 – 50 gallons of paint depending on the tank size. You are able to leave the system with a coating in it as long as the coating doesn’t have a limited pot life.

However, the price of pressure tanks is around $950 compared to gravity or suction-fed guns. Clean up takes a bit longer and the extra hose can make working with the gun less comfortable.

When considering whether to purchase a pressure pot feed spray gun, the volume of the paint you want to spray has to be taken into consideration.

As seen in this guide, tanks can range from 2-50 gallons and if you’re working on a bigger project, you’re going to want a bigger tank.


More Considerations…


Your coating is another issue to contemplate. You need to determine if your coating needs to be agitated to be able to be sprayed.

Best bet is to consult your coatings provider or the data sheet. In addition, if your coating is waterborne, you may want to consider a stainless-steel pressure tank to avoid corrosion.

What is included in the package is also a must to consider. For example, in this guide, we have covered spray guns which include the tank and others which have not.

If you are looking for something that gets you spraying straight away, you may want to consider buying a kit to save you money, time, and effort.


Conclusion


In this review guide, we’ve reviewed the top pressure pot feed spray guns available on the market. From this, you need to evaluate your painting project and your requirements.

How much paint are you going to use? What kind of paint? What is your object and how big is it?

Do you want a full kit or to buy the parts separately for customization?

By answering those questions, you can pick out the perfect spray gun – be it one with a huge tank for a boat or a small one for a piece of furniture.

Either way, it is going to be quicker and more cost effective than using a roller.
