We all want to put a lot of work and more detail into our artwork and DIY projects. But the process of using a brush and paint can take hours, thus making the whole process tiring and not enjoyable. Thus, the gravity feed spray gun is the best option for more detailed and precise artwork. Not only is this gun suitable for a variety of projects, but it also gives a fantastic finish that is compared to none. So, how does it work?

 

 

 

Defining a Gravity Feed Spray Gun

The main difference between the two types of spray guns is how the paint gets released into the airbrush spray gun. Gravity-feed spray guns are well known for having a cup that is found on top of the gun. As the name suggests by itself, paint uses gravity to flow into the airbrush sprayer. Thus, paint is loaded into the nozzle for it to be used. On the other hand, siphon-feed guns have a paint cup that is attached below the spray gun. Thus, the gun uses pressure to pull the paint. These guns are suitable for large-scale projects because the spray gun can pull a large amount of paint into the cup.

Thus, the main difference rests on how the paint is loaded into the nozzle. This might be a small detail, but it plays an important role in how the spray guns work. We will look at the best spray guns below:

 

 

HVLP Gravity Feed Spray Guns

HVLP (High Volume, Low Pressure) is the most common system used by gravity feed spray guns. These spray guns operate at low pressure, but they release a large quantity of paint. The low pressure gives you control when using the spray gun. Finer details can be created since less paint will be over-sprayed. Because of the low pressure, this spray gun is not suitable for large-scale projects. Thus, it is only suitable for small and more precise projects.

Why Choose a Gravity Feed Paint Sprayers?

The most usable and incredible gravity feed spray guns have a lot of benefits. They are suitable for small projects and are mostly preferred by hobbyists or anyone doing basic DIY projects around their homes. The following are some of the benefits you gain when using the best gravity feed spray gun:

  • Gravity feed spray guns operate under low pressure. Thus, they are suitable for beginners since they are not too complicated to handle. This low pressure that is close to the compressor makes the spray gun easier to use.
  • These guns are not wasteful because they use low pressure in the process of atomizing paint. This is because less paint will be released at each time, thus preventing wastage.
  • Because of the few over sprays, it also means there will be less mess. This is because an airbrush causes a lot of mess when it is operating, thus a gravity feed spray gun is mess-free. It is most suited for people who do indoor projects.
  • These guns offer high levels of precision that allow you to have much control over the gun. The spray gun will produce a fine finish since it will be controlled when doing finer details. For this reason, the spray gun is most suited for small projects and models which require a lot of finer details.
  • This gun also makes the process of changing paint quite easy. You just empty the top-loading cup, use the color to spray the gun clean, and then add your new paint.
  • Besides making the process of changing colors easy, you can also mix the colors with much ease. This will enable you to create the best color transitions and the most intense color details when you are airbrushing.
  • This gun is quite easy to clean as compared to the pressure gun.
  • The gun is quite small and easy to carry around. You can easily pack it for traveling and use it for a variety of uses.
  • The spray gun can handle a small amount of paint. This means that you can load a small amount of paint for the best quick touchups. This is quite a difficult process if you are using a large paint sprayer.

Drawbacks of Gravity Feed Paint Sprayers

Besides having a lot of benefits as listed above, these gravity feed spray guns have their drawbacks too. The following is a list of some of the drawbacks associated with using a gravity feed spray gun:

  • The paint cup is quite small; thus, you will not be able to carry large amounts of paint when working as compared to using a siphon-feed gun. Thus, the gravity-feed spray gun is not suitable for large-scale projects since you will be forced to do a lot of refilling all the time.
  • These guns work best with thinner paints. So, you cannot use them with heavier paints. Or else you might need to thin down the paint before use.
  • The gun is not suitable for spraying at different angles because the paint must flow down from the cup that will be on top of the gun. The design of the gun is not suitable for spraying upside-down or from the side.

Factors to Consider when Buying a Gravity Feed Spray Gun

Getting the correct gravity feed spray gun is quite an important process and it should be taken seriously. The whole process depends on specific situations because most of the gravity spray guns look alike. Thus, we have come up with a list of some of the specific features you can look for when buying one:

 

Size of the Cup

The paint cup used by the spray gun is an important aspect to consider. The amount of paint is determined by the size of the cup. Thus, determining how long you can use the spray gun. It is advisable to stick to a paint cup size of 600cc. Thus, the correct cup size can carry enough paint for easy use. However, some artists and painters prefer a small-sized cup for smaller projects, and others prefer big-sized cups for bigger projects.

 

Size of the Nozzle

The size of the nozzle matters a lot because it is the part of the spray gun that expels paint. The size of the paint stream is affected by the nozzle size. Moreover, it also affects how the paint will be atomized. Big-sized nozzles are perfect for bigger projects while the opposite is true for the small nozzles.

You can use a small nozzle for thin and more detailed lines. It is best to use a nozzle size of 0.3mm to 0.5mm. These sizes are perfect for a variety of uses. Other spray gun models come with adjustable nozzles that you can change and use the size you want at any time.

Airflow Adjustment

The spray gun should give you enough control over the airflow. This is because airflow affects the outcome of the spray pattern. If you can adjust the airflow to suit your preferences, then the spray gun will be easier to use. You will also get excellent and precise results.

 

Dual-Action or Single-Action Trigger

There are two types of triggers associated with gravity feed spray guns. The single-action trigger is only capable of pulling in one way. This means that it is only capable of delivering an amount of paint spray that is fixed. On the other hand, you can pull the double-action trigger in two directions and you can adjust the paint flow size. This type of trigger can be used in a variety of ways and the spray control pattern can be adjusted. Most painters prefer the dual-action trigger, but it requires a bit of experience to be able to control the paint sprayer without making a mess.

 

Weight and Size

Most of the gravity feed spray guns are quite small, thus working with a heavier machine can be tiring unless if you are working on a large project. However, choose a lightweight paint sprayer that is compact enough to make the painting process much easier.

 

External/Internal Mixing

You should choose between an internal or external mixing system when you are choosing the right gravity feed spray gun. This is the atomization point where the air mixes with paint. Most sprayers use an internal mixing system, and it is used by most serious and professional users. The external mixing system is perfect for small applications.

 

 

What are Gravity Feed Spray Guns Used For?

These spray guns are not suitable for large projects since they use lower pressure when they are spraying paint. They are best suited for small paint applications, DIY jobs, touch-ups, and so on. This depends on the cup size too. Gravity feed spray guns are also perfect for normal home users and painters.

 

Cleaning the Paint Sprayer

The spray gun must be cleaned after every session. This also goes for when you are changing colors. You must clean the gun whenever you change colors. Thus, gravity feed systems are quite easy to clean. If you are doing a thorough clean you have to take the gun apart first and then clean it. You must do this process with a proper cleaning kit or an airbrush.

Cleaning the spray gun is important! Do not joke around. Consider the cleaning kit when you are purchasing a gravity feed spray gun as this will be one of the processes you will be doing regularly. Do a quick clean when you change your paint to a new color.

This will prevent unwanted color mixes which might result in strange colors being expelled. You can do this quick clean by spraying water or a cleaning solution until the spray is clean. The one that is easier to clean is the spray gun that has a paint cup on top.
