Spray painting is the easiest way to paint a surface with an even coat. Spray guns produce even, uniform, fine finishes which are flawless in a very short period of time compared to brushes and rollers. Basically, there are two types of spray guns; Suction-feed and gravity-feed.
Suction feed spray guns use that air which passes over the coating to draw material through suction cup’s tube as well as the nozzle. They are easy to use. Since they automatically have the correct atomization air pressure set by a pressure high enough, you lack the power to control the atomization like you can in gravity feed spray guns. Besides this, many people have noted that suction feed spray guns do not allow for quick colour changes so easily. The finish is not so fine since it requires larger fluid nozzles and it is difficult with heavy-bodied coatings. Suction feed spray guns are best when used in adhesive applications for less viscous coatings or in paintings where finish quality isn’t such a huge concern.
Gravity feed spray guns on the other hand are quick and easy to clean up. Best in painting smaller batches of coatings, they are known to provide fine atomization and can also be used with all types of spray guns (HVLP, Conventional etc.). The main downside of a gravity-feed spray gun is that it requires material to be able to flow on its own. This means heavy body coatings will not spray well with this type of gun. A gravity feed spray gun has a myriad of advantages over a suction feed spray gun.
- It is easy to disassemble and clean
- Gravity feed spray guns are very affordable compared to suction feed spray guns
- You easily achieve a fine finish with these spray guns
- Can handle slower fluid amounts which are ideal for touch up work and other smaller projects
- Can change colours easily with a disposable insert liner
- Has better control of atomization of air compared to suction fed spray gun
- Offers less air pressure which reduces overspray and results in less
They are commonly used in automotive painting, wood finishing on smaller projects (like painting individual cabinets or other furniture pieces) touch up painting of metal fabrications and colour matching in high production facilities or inserts like Dekups.
As you can judge by yourself, a gravity feed spray gun is the best if you need the best results. However, each design aspect has some advantages over the rest, which makes settling on a given gravity feed spray gun more complicated. What do you consider when buying a gravity-feed spray gun?
- Prominent features. One of the things you need to look out for when choosing a gravity feed spray gun is its prominent features. These include its design, the mix system, trigger adjust flow and its feed type. The design enhances or reduces the final outcome. Ensure its construction is solid, has a vast customization since you do not know which details will be needed in the different works you will be doing.
- Mixing system can in a gravity spray gun can install either internally or externally. If you are looking forward to detail works, then the best system to go is the internal mix. However, if you don’t need much effort especially for the small areas then you can go for the external mix. Another feature is the trigger of the gun. It can be dual action or single action. A single action trigger automatically pushes down and pulls away when paint auctioning while with a dual action trigger you do it yourself, which makes a single action trigger a better pick.
- An adjustable flow makes spray painting so easier. Due to this, you should go for a gravity feed spray gun that allows fluid adjustments as you might be required to paint slowly for perfect finishing while in some instances you only need to cover the surface with paint, nothing more.
- The cup size. Gravity feed spray guns come with cups. While many people believe that having a big cup hinders maneuverability and tires your hands sooner, you should not forget that it allows you to cover a large surface in a single application without having to go back and forth adding more paint. Most advice on a 600cc cup which is neither too big nor too small. Check the spray gun’s filters as they prevent dust particles from mixing with ejected paint, this ensures a smooth coating.
- This is a consideration in every purchase we usually make. The market has very many gravity feed spray guns at varied prices. Once you have checked out all the gravity feed spray guns, you should now look at the cost. A newer and more advanced gravity feed spay gun will cost more. You however need to know that the most expensive spray gun isn’t necessarily the best for you, since some other cheap basic gravity feed spray guns might be offering what exactly you are looking for.

However, you can fully rely on buyers who have bought the item before you. It is advisable that you read what they say about an item, the complaints and the applause they give.
