Gravity-feed guns rely on gravity to cause the paint to flow down. HVLP (which stands for high-pressure, low-volume) guns use both siphon and gravity-feed technology. No matter what method your spray guns uses, it should be able to get the job done, though some methods are better-suited for certain applications than others.
How does a gravity spray gun work?
HVLP and Gravity Spray Guns use gravity in a cup to feed the sprayer. This means you use way less air to atomize the paint into a mist of spray. The cup sits on top of the actual spray gun. So even without air, if you squeeze the trigger with material in the gun, it will squirt.

How Does A Spray Gun Work?
As we have covered above, a paint gun atomizes the paint into minuscule droplets. There are some components in the guns that allow the device to achieve this effect.
How does a paint sprayer work?
In all the variants of a paint sprayer, there is a method to deliver the paint fluid. For example, the liquid is pressurized in pressure spray painters, allowing the paint to flow out. In siphon guns, the paint is kept inside a reservoir where air movement creates a siphon, which pushes the color through the nozzle.
What is a spray gun?
A spray gun is a tool that is used for spreading and spraying paint in a controlled motion. There are many different types of paint sprayers, and depending on the type, the working principle may vary. However, the most commonly used tools use compressed air that atomizes the paint and directs the particles towards the intended surface.
What is a HVLP sprayer?
HVLP spray painters or High-volume Low-pressure units use low air pressure to create a large volume of paint. In HVLP units, you get a drastically reduced overspray, and as a result, the delivery of paint is highly efficient. Almost all of the automotive paint guns use HVLP technology.
What is the needle on a spray gun?
Fluid Needle. The final part of the spray gun that you need to understand is the fluid needle. It is attached to the trigger of the unit and controls the flow of the painting material. When you press on the trigger, it opens the air valve and retracts the needle. The harder you press on the trigger, the more of the fluid can pass through it.
What is the most important part of a paint sprayer?
Air Cap. The air cap is the most crucial part of the spray gun. Factors, such as spread patterns and the flow of paint, depends on this part of the paint sprayer. It comes with drilled holes that are precisely positioned to create the design of the paint that spreads on the surface.
What kind of air do you use to paint?
However, the most commonly used tools use compressed air that atomizes the paint and directs the particles towards the intended surface.
How much pressure should I use for a paint gun?
Make sure to read the paint can and gun instructions to see what the recommended PSI is. Usually, water based paints need less air than lacquer or enamel paints. The average range used is 40-80 PSI. You can set the PSI on your compressor or with an air regulator that can be attached to your gun or air hose.
How far away should you hold a spray gun?
When you are happy with the quality of spray during your testing, it's time to SPRAY for real! You want to hold the gun about 5-8" away from the surface you're spraying (that's about a fist or spread out hand's distance). Hold the gun perfectly perpendicular to the surface. If it's tilted, you'll get uneven coverage.
What does a fan do in spray gun?
The fan determines the width of the spray. Set the gun to a wide fan for larger pieces to be sprayed and smaller fan for smaller pieces. If you use a wide fan for a small piece, you'll have a lot of over spray which wastes paint and money.
How to connect a compressor to a gun?
Turn your compressor on. Attach a coupler to the plug you added to the gun. I recommend a quick connect to the end of your air hose. This will make a HUGE difference. It allows you to easily and quickly connect/disconnect your gun from your air hose. You can also attach one to the other end of the air hose to make connecting to the compressor easy too. Set ithe compressor to the proper PSI. Make sure there are no air leaks from the hose or the gun. If there is, see the Troubleshooting page.
How much air pressure do you need for water based paint?
Usually, water based paints need less air than lacquer or enamel paints. The average range used is 40-80 PSI. You can set the PSI on your compressor or with an air regulator that can be attached to your gun or air hose. Ask Question.
How to pour paint in a gun?
Place your gun in the gun holder (if you purchased one) so you can pour your paint in. Fill the cup 1/2-3/4 full. Don't fill it to the top because it will definitely splash out; plus the gun will be heavier and your arm will get tired faster. Place the lid on and make sure it's tight, you don't want paint dripping out from under the lid and ruin your work.
What is a gravity feed gun?
This particular type of gun is called a gravity feed or cup gun. It means the paint cup is above the gun and gravity allows the paint to go into the gun. There are a few different types of guns, but this type is my favorite (I'm honestly not sure why lol. I think starting out it was the easiest one for me to use).
How is paint sprayed?
All paint sprayers function based on the same core principle: they turn fluid paint into numerous atomized, tiny droplets, which are then sprayed onto a surface. However, different spray guns use different methods to achieve this. There are four major types of paint sprayers: siphon, pressure, HVLP and gravity-feed guns.
What are the parts of an airless paint sprayer?
Parts. An airless paint sprayer is made up of four parts: a hose, a tip, a pump and the gun itself. The hose has two distinct ends. The narrower ends goes into the paint while the wider nozzle will connect to your sprayer. The gun controls the flow of paint while the size and shape of the tip controls the amount of paint that actually comes out.
What is a HVLP spray gun?
HVLP (which stands for high-pressure, low-volume) guns use both siphon and gravity-feed technology. No matter what method your spray guns uses, it should be able to get the job done, though some methods are better-suited for certain applications than others. What’s often more important is the type of gun itself.
How does a siphon gun work?
In siphon guns, paint is pulled out of the tool’s reservoir using a siphon created inside the gun. With pressure guns, the fluid flows out when pressurized. Gravity-feed guns rely on gravity to cause the paint to flow down. HVLP (which stands for high-pressure, low-volume) guns use both siphon and gravity-feed technology.
