On this page, we are going to take a closer look at the Harbor Freight spray gun range. Harbor Freight has been around since 1977, and has around 30 million customers. They do not actually manufacturer most of the tools that they sell. Yet they still have a reputation for selling high quality tools, for a competitive price.

Their approach is to buy from the same factories that make tools and equipment for the top brands. They then sell them at a lower mark up than their competitors do. Therefore, a Harbor Freight spray gun is an excellent way to get your hands on a top quality paint spraying head, and do so for a relatively low price, which is why we have included their products on this site.

Below we review their top three spray guns. However, before we get into the nitty gritty of which one is best for you, we think it would be helpful for us to explain why you may need to buy a new spray gun.

The right spray gun saves you time and money

Provided you buy a good quality spray painter, and learn how to use it, you will save yourself a lot of time and money. Painting and decorating becomes something you enjoy, and look forward to doing.

With the right sprayer in your hand, a job that would have taken you all day only takes you a few hours. Plus, the finish is every bit as good as a professional’s is, with the advantage that you are not faced with a big bill.

Paint sprayers really are great, but like any tool, you need to maintain yours. As parts wear out you have to replace them. Perhaps the most important part of your paint sprayer is the spray gun.

What happens when your spray gun starts to fail?

This part delivers the paint, lacquer or stain to the area you are covering. If it is not kept in good condition, the spray nozzle becomes more prone to clogging. This results in an uneven distribution of paint.

If the seals between the spray gun head and the paint delivery pipe or the container or pot start to wear, the pressure delivered in no longer consistent, or strong enough. When that happens, the amount of paint delivered to the nozzle is no longer consistent. This means that some areas end up with too much paint on them, while others are practically bare.

Simply put, a poorly maintained, worn, or aging spray gun can render an otherwise good spray painting system useless. Therefore, you will need to consider replacing this part of your HVLP or airless paint sprayer, every few years.

Harbor Freight 4oz Detail Spray Gun

For anyone using a spray gun evenly coating detail areas like the frame of a door, a trim feature on a car or a carved surface is tricky to say the least. Because the paint hits the surface at different rates, it is hard to get an even amount of material to adhere across the item. In this situation, control is of paramount importance, which is why you want to be able to adjust the spray width, and the rate at which the paint is delivered.

This Harbor Freight detail spray gun allows you to do exactly that. It is made from metal, so is strong, yet at just 0.8lbs is also lightweight, which makes it easy to control. The flow rate can be adjusted from a small circle, which is just 88mm across up to a circular pattern of 101mm.

If you are spraying cars or are an artist producing murals this detail spray gun is a very good option. If you are a homeowner who wants to spray paint their wooden window frames or panel doors, it is also handy to have in your toolbox.

Harbor Freight 20oz Gravity Feed Spray Gun

This Harbor Freight gravity fed spray gun is extremely versatile. It can be used for priming or painting. You can load the 20 fl. oz. cup with paint (including metallic paint), primer, lacquer, urethane and enamel, so it is extremely versatile.

It is a high volume, low-pressure (HVLP) spray gun, which can be used at a psi of between 20 and 70. As a result, it delivers a good supply of paint, but not so much that overspray is a big issue. The fan pattern is adjustable, as is he flow rate of the fluids being used, so it produces a high finish, and can be used for a huge range of spraying jobs.

The manufacturer of this Harbor Freight branded spray head is Central Pneumatic. They have been making equipment for Harbor Freight for decades, and have a reputation for making high quality products that are well engineered.

This spray gun is ideal for use in a spray shop, or for the hobbyist. In addition, it is also a good option for someone who is working on a large DIY project.

As mentioned earlier, this brand is manufactured by companies that make other products. If you’re considering this 20 ounce sprayer on Amazon, this is an exact copy of the 20 oz. model from Central Pneumatic, which may be a better buy for Amazon Prime members.

Harbor Freight 64oz Professional HVLP Spray Gun Kit

If you are a professional who is spraying every day, for long periods, this is a great spray gun kit. This spray gun has a paint transfer rate of 75%, which means it is extremely efficient. With this HVLP spraying gun, you should use up to 40% less paint, lacquer or stain, than normal.

The fact that it has a 64floz cup allows you to cover large areas without the need to pause, which make it ideal for use in a body shop. It is quite heavy to hold and handle, so some hobbyists and DIY users may find it a bit more difficult to control than a standard spray gun.

There is a definite knack to using this type of paint spray head, but once you get used to it you can work fast. The two 80” hoses ensure that you have good reach and the flexibility to get into all of the tight or awkward spots.
