How can you save time on a do-it-yourself paint project? One of the more popular ways is to use an air spray gun. Not only does a paint sprayer do the job in less time, but it can also do it more efficiently. One special type of air spray gun is the gravity paint gun. This simply means the paint cup that holds the paint is situated on top of the spray gun. To help you choose the best gravity feed spray gun, we have put together a basic guide.



What Is a Gravity Feed Spray Gun?

When referring to a spray gun, it is a general term as there are various kinds available. The general description includes a spray gun with a trigger, once the trigger is applied, the compressed air atomizes the released paint which moves through the nozzle. Two of the more common types include the siphon and gravity spray gun.

HVLP Gravity Feed Spray Guns

Both of these perform a similar function by spraying paint onto surfaces, the difference is in the way the paint is dispensed. Siphon feed spray guns are the most well-known and have a paint cup placed at the bottom of the spray gun. Enough pressure must be produced so that the paint is sucked up into the spray nozzle.

These were widely used and popular in the autobody repair industry.

A gravity feed air spray gun came after the siphon spray gun and is considered easier to work with. They also waste less paint when spraying and cleaning them is a little easier. There are two main types including the High Volume Low Pressure (HVLP) Gravity Feed Spray Guns and the Low Volume Low Pressure (LVLP) gravity paint gun. You can also use the term pneumatic paint sprayer, as the paint sprayer uses compressed air to spray the paint. This means you will need a compressor or a turbine to apply the paint with a gravity paint gun.

A gravity feed paint sprayer has a paint cup placed on top of the air spray gun. Gravity then helps to drive the paint into the spray gun. The gravity or pneumatic paint sprayer offers quite a few advantages.


The Advantages of Using a Gravity Spray gun

The first advantage of a gravity feed paint sprayer is the fact that it uses less air pressure and will give you a high-quality finish. Since they produce less overspray, clean-up is easier. When using less air pressure, you also use less paint, so you do not waste as much as other paint sprayers. This also provides more control over the whole process, without the paint flying everywhere. Below are a few more advantages.

  • Offers a more controlled system that provides an even spray and a finer finish
  • Offers good-quality paint cover
  • Requires less air pressure than a siphon paint sprayer
  • Painting is done a lot faster than other methods
  • Less air pressure ensures there is less overspray, which means less clean-up
  • Widely used and support and training is easy to come by
  • Saves money as you use less paint
  • HVLP gravity feed spray gun can complete larger projects in a shorter time
  • LPLV (Low-Pressure Low Volume) is a lightweight and affordable option, great to use for do-it-yourself projects at home. Can be used for precision work


The Disadvantages of Using a Gravity Spray Gun

There is also a small number of drawbacks when using a gravity spray gun. So, depending on the job you want to do and if you are going to be using the paint sprayer regularly, you will need to decide if it is what you are looking for. Below are some disadvantages for both the HVLP gravity feed spray guns and the LVLP (Low-Pressure Low Volume) spray guns.

The Cons of HVLP (High Volume Low Pressure) Spray Guns

  • Prone to clogging and then spraying an uneven pattern
  • Should not be used with thick paints, you will have to thin paints
  • Might take longer to clean the spray gun as you will have to disassemble the nozzle, clean the cup and filter inside
  • Has a shorter hose and you may need to carry everything around
  • Overspray is more, which wastes paint


The Cons of LVLP (Low Volume Low Pressure) Spray Guns

  • Again, thicker paints cannot be used unless they are thinned
  • You will need to refill paint more often
  • Has no real power and takes longer to complete painting
  • It can take time to learn and operate the sprayer effectively

To say one paint sprayer is better than another is difficult, as they all have pros and cons. However, a professional might choose the siphon-feed spray gun for what it can offer. The gravity feed paint sprayer, on the other hand, is better for smaller jobs and is best for novice painters.


The Differences Between an HVLP and LVLP Gravity Feed Spray Gun

Air spray guns might be similar in appearance and perform a lot of the same functions, but there are a few differences. The HVLP (High Volume Low Pressure) spray guns are perfect for thinned paint, for example, spraying latex paint with a gravity feed gun. It performs faster than the LVLP (Low Volume Low Pressure) and can be used for spraying cabinets, furniture, and walls.

The LVLP (Low Volume Low Pressure) is good for detailed applications, which makes it a better option for more professional painters. Many professionals prefer using the LVLP (Low Volume Low Pressure) for automobiles as it provides a finer and smoother finish. Next, is a table showing you the differences more clearly. Note, cfm describes the cubic feet per minute and psi indicates pounds per square inch.

When Is a Gravity-Fed Spray Gun the Best Option?

Gravity-feed paint sprayer systems are ideal for small projects, it will take you some time to do larger surfaces as it is much slower than the airless paint sprayers. The paint cups also tend to be smaller, so if you paint a larger area, you will be re-filling many times. Thinner mediums are also better for gravity spray guns. Thicker paints such as latex or primers can also be used, however, you will need them to get the proper viscosity that will work. Some of the more well-known applications for a gravity spray gun are as follows.

  • Applying finishes to furniture
  • Painting molding, gutters, and trims
  • Doors, cabinets, shutters, and walls
  • Automobile applications
  • Painting appliances, shelves, and pipes



Guide to Purchasing the Best Gravity Feed Paint Sprayer

If you are a seasoned professional with knowledge and experience, it is a little easier to know what to look out for when purchasing hvlp gravity feed spray guns. However, if you have just begun to use a paint sprayer, things can seem a bit confusing and intimidating. You will need to consider several things like the cup size, the type of pressure gauge, or what type of spray pattern does the paint sprayer produces? In the end, you will need to select a spray gun that does the job you want. Let us have a look at a few more important factors when it comes to purchasing the right gravity paint gun for you.

Pneumatic Paint Sprayer


Gravity Feed Paint Sprayer Features

Always consider the different features and choose a paint sprayer that suits your requirements. Have a look at the design, is it easy enough to move around or will it tire you out easily as you work for longer periods. Also, choosing a paint sprayer that can be customized can help you save on future projects. More features to look out for include:

  • Trigger action: Dual-action where you push down for air and back simultaneously for paint, a single action does this in one movement
  • Mixing systems: Is it an internal or external mix? This is the mixing of the air and paint either inside the nozzle or outside the spray gun
  • Feed type: Gravity feed or siphon feed
  • Flow rate: High Volume Low Pressure or Low Volume Low Pressure
  • Bleeder-type paint sprayers: These provide a continuous flow of air while the turbine or compressor is on. Versus the non-bleeder option which only releases air once the trigger is pulled


Adjustable Settings

You need to look at paint sprayer systems that allow you to adjust the settings like the air pressure or flow. This will help to make the spray system more versatile, and you can use it on different projects for adjustable precision painting. The best feed type is a combination of HVLP and standard.

Air Spray Gun


Nozzle Size

The spray gun can come in various size nozzles, and some will provide you with various sizes in a set. Sizes can be from 1.0 mm to the larger 2.0 mm. The correct nozzle size is important for the type of job you are doing. The smaller more precise painting will require a smaller nozzle and, vice versa, a larger area needs a larger nozzle.

The fluidity is also affected, thinner and thicker paints will react differently.


Cup Size

The larger the cup, the less maneuverability you will have and if you work for a long time, it may tire your hands. However, the bigger the cup, the more paint you have, so you do not waste time refilling. So, it is up to you how you feel and what the paint job involves. The different sizes vary from 600 CC, which is 0.6 liters or 20 fluid ounces, and 1000 CC, which is one liter or 33 fluid ounces.

Best HVLP Gravity Feed Spray Gun



Makes sure you look around and read reviews to find the best gravity feed spray gun. You do not want to purchase a low-quality product that will not last and does not provide a good finish. There are expensive options and more reasonably priced options available. What you buy will depend on your needs but choose wisely and do some research and do not go out and buy the first option you see.

Considering a well-known and popular brand can also be a way of choosing something worthwhile.


Ease of Use

The handle needs to be comfortable to hold for long periods and consider a non-slip grip so that you do not accidentally drop the sprayer. Again, the weight of the air spray gun should be considered. A heavier paint sprayer might provide a little more control, but over a long period, it will become uncomfortable to work with.

Basic Guide for Using a Gravity Feed Paint Sprayer

When using a gravity feed paint sprayer for the first time, it can be a bit difficult. You should practice handling the paint sprayer and you will learn to produce the best finish. Before you even start to use the air spray gun, you will need to prepare the paint itself. There are spray guns that have filters, however, many do not which is why you need to run the paint through a filter yourself. This helps to lower the risk of clogging.

Gravity Feed Paint Sprayer

Always read the product instructions when it comes to thinning the paint. Each system can be different, so it is best to check, however, the highest level for paint thinner is 20 percent. Do not go over this percentage. You will need an air compressor or turbine, and this should then be connected to your gravity spray gun. Set the air pressure to the specific spray gun specifications. Next, add paint to your cup which is attached to the top of your spray gun. You will then need to switch the compressor on to activate the system.

Always test out your air-spray gun on a separate surface like a piece of cardboard before painting your actual surface.

When testing the sprayer out and you notice clots of paint, this will not produce a smooth coat and you might need to add more paint thinner. If you observe thin lines appearing at the top or bottom of the cardboard, the paint might be too thin, and you will need to thicken the paint. Once you have achieved the correct levels and spray patterns, you should be able to get a smooth and even application. Move the spray gun in a smooth, sweeping motion, and apply thin coats. You can always pass over a section more than once. Several thinner layers are better than thick coats to achieve an even finish.

How to Clean a Gravity Spray gun

So, the spray painting project is done and now you are left with an air spray gun that is full of paint. You might be thinking that the fun is over, and the hard work is now looming in front of you. However, if you follow the steps for cleaning an HVLP gravity feed spray gun, it should not be that difficult. Cleaning your spray gun is important, as you want it to last a long time.

Just like most things, you need to apply good maintenance for the best results.

The first thing you need to do is to make sure you start the cleaning process as soon as possible. You do not want the paint to dry as this will make the job more difficult. Any paint that clogs the spray gun, will affect the spray gun if used again and if not cleaned properly, the spray gun will not function properly. Begin the cleaning process straight after you have finished painting, once you have learned the clean-up process, the next time it must be done, it will be much faster and easier.

Disassembly of the spray gun is not complicated if you do a little research on your specific gun. You should be able to get information from the user instruction manual, or you can have a look online where there is plenty of resources. Each spray gun is made differently, and you will need to familiarize yourself with the components. Careful not to damage any of the parts as reassembly will be difficult or impossible.

When cleaning, try to keep the more delicate and smaller parts separate from the larger parts.


Material Needed for Cleaning

When cleaning your air spray gun, you will need a few things to complete the process. Some of these items should already be available, or you can purchase a cleaning kit, which should have everything you need. Some of the gravity spray gun products also come with cleaning brushes and even a wrench to help with disassembly. Some of the things you will need for cleaning will include the following.

  • Warm water and soap
  • Protective gear: Goggles and gloves
  • Thinner for paint
  • Rags and paper towels
  • Cleaning brush
  • A plastic bucket
  • Toothpicks
  • Wrench


Taking the Gravity Paint Gun Apart

Remove the paint holder from the spray gun body and leave it to dry. You can then take the paint gun apart. Unscrew the air cap and carefully unscrew the paint needle. This is spring-loaded, so hold it in place or it will spring out. Take the wrench and unscrew the inside section of the air cap. As you disassemble, place the smaller spray gun parts separately from the larger ones.

Cleaning the Paint Cup

The cup will have a lot of paint on it, so this will need to be cleaned thoroughly. Fill the cup with cleaning solution and replace the cap, shake, and pull the trigger. Face the paint sprayer towards your bucket so that the paint can spray into it. This will also allow the paint cleaner to run through the paint gun to loosen and remove most of the paint. Take your rag or paper towel and dip it into the paint cleaning solution, use to wipe the inside of the cup. Wear gloves for safety purposes.

Make sure to also clean the inside of the cap.


Cleaning the Spray Gun Parts

Once everything has been taken apart, you can now submerge all the parts in a cleaning solution or paint thinner. You can also use soap and water for this process. The important thing is to handle the parts carefully, you do not want to damage anything. So, take the larger parts like the gun body and the cap parts and submerge them in a bucket together. The smaller and more delicate parts like the needle in a separate container.

Once it has all soaked for a few minutes, you can remove everything from the cleaning solution and place it onto some paper towels. Now you can use the brush as well as the toothpick to get all the stubborn paint off. You can use the toothpick carefully for smaller grooves and ridges. Take a rag with some cleaning solution and wipe the spring and fluid needle gently until properly cleaned.


Assembling the Spray Gun

The last step is to put everything back together. Your first step is to place the spring and needle back into their proper place. Replace and screw the inner cap then the outer back on. Take the paint cup and place it back onto the body of the spray gun. Once you have done the entire cleaning process once or twice, it should become easier and faster the next time you have to do it.

Frequently Asked Questions


Are Gravity Feed Spray Guns the Best Choice?

A gravity feed paint sprayer uses less pressure when spraying, which does make it easier to use. This also means there is less paint wasted when spraying. There are also quite a few advantages to using a gravity paint gun. However, a gravity feed paint sprayer will not handle larger jobs as effectively as other paint sprayers. So, it depends on your project and preferences when choosing a paint sprayer. One is not necessarily better than another, it is more about choosing the features that suit your needs.


What Makes a Gravity Feed Gun Different From a Siphon Feed Spray Gun?

The main difference is the method the paint is fed into the paint gun nozzle. The gravity feed paint cup sits on top of the spray gun, while the siphon-feed paint cup fits in at the bottom. The siphon feed spray gun needs quite a lot of air pressure to suck the paint up, while gravity and air help with the gravity feed spray guns.


Do You use More Paint When Using a Paint Sprayer?

When using the best gravity feed spray gun, the amount of waste should be less than other paint sprayers, as more paint reaches the surface and there is less overspray. However, when spraying paint, you might need to buy more paint when compared to using a brush or roller. You do get a better finish and the painting is done much faster with a paint sprayer.


Are you Able to Spray Latex Paint with a Gravity Paint Gun?

Spraying latex paint with a gravity feed gun is possible. You will need to use a nozzle size that is 2.0 mm or more for the latex paint to move freely through. Anything smaller will clog the nozzle and you will not get a smooth finish. You might also have to thin the latex paint for it to work with a gravity spray gun.
