Review Summary:

Quality LVLP spray guns that are capable of handling various paint viscosities tend to cost quite a bit, especially if they are designed for avid professionals. The Astro 4008 is a good choice for people who are planning on tackling a big project that requires a steady and consistent spray gun performance. This particular model is great for a variety of things including painting a fence, furniture, carpentry, and even cars, regardless of user’s expertise and experience. It’s relatively simple and easy to use, but that doesn’t mean it will always yield impressive results. In order for that to happen, one has to dive deeper into the features and capabilities of the said gun.

In case you’re interested in purchasing one for yourself, go ahead and read some of the details we were able to draw from our review so that you know what to expect. It isn’t the best model on the market by any means, but it’s definitely a worthy investment for people who are looking to get an affordable tool that doesn’t require a lot of experience.

Specifications:

  • Two-piece construction with an exclusive air valve design
  • Adjustable fan pattern control
  • 1-quart capacity dripless cup
  • 8mm nozzle
  • Requires 7-12CFM / 3HP compressor

The Basics


As far as the basics of this particular spray gun go, it offers pretty much everything you’ll need in such a tool. It’s a great solution for many applications, but you should keep in mind the fact that it does not do well with thick paints. Therefore, make sure you always use thinners when operating this gun or else the whole project might come to a halt once the unit malfunctions.

The adjustable spray pattern is a neat addition which allows you to fine-tune the coating and keep it evenly distributed. It allows you to adjust up to an 11″ fan size from an 8″ distance which isn’t particularly impressive per se, but it’s worth mentioning.

The Features


The Design


The design is pretty neat, although quite conventional. In other words, there aren’t many things that would make it look or feel special. However, the anti-spill air feed line is definitely something worth mentioning. It allows the user to hold the gun in any position or angle without worrying about spilling the paint from the cup. The gun itself is pretty ergonomic, which sounds somewhat irrelevant, but it’s actually quite an important feature, especially if you’re planning on tackling a big project. The ergonomic design prevents fatigue and allows you to use the tool for long periods of time.

The overall weight of the unit is about 3 pounds (1.4kg) which is definitely not the lightest one around, but its weight shouldn’t cause too many issues. However, you should keep in mind that it weighs more once the cup is filled. Either way, there could be some issues with fatigue if one is working on a particularly large project, but it isn’t a primary concern.

The air compressor is required to have at least 3HP and be capable of keeping the operating pressure at 50-60 PSI. Anything less than that can and most probably will cause some sort of a predicament. Therefore, it’s essential that you check the specifications of your air compressor before investing in this gun. In case you don’t own and are planning to buy one, make sure it’s sufficiently powerful. Needless to say, the requirements aren’t particularly hard to meet, so you shouldn’t run into any major issues.

Maintenance


Unlike with kits in which the user gets all the necessary tools for maintenance, you will have to use your own set of tools for this particular gun. However, there’s no need to worry about it as it doesn’t require any proprietary or specific tools. The best course of action here is to read the instructions and user manual to see the proper way of dealing with maintenance. Make sure you clean and wash the gun after every use or else it may malfunction.

What we liked about it


The design and quality are pretty good. Even though it’s not the best thing on the market by any means, one wouldn’t expect this kind of quality considering the affordable price. Speaking of the price, that’s also one of the things we liked about this product. The paint gun market is quite saturated with all kinds of different units, and a worrying number of them aren’t worth investing in. That’s why most people refer to the price when figuring out whether a unit is of good quality. However, that’s clearly not the case with this particular model because while it’s quite affordable, it’s still a high-quality tool.

The ergonomic shape of the gun is also a pleasant sight, especially if you’re a devoted painter that uses spray guns on a daily basis.

Struggles with thicker paints

What We Didn’t Like


The trigger control is too crude for lacquers and topcoats. That doesn’t mean it’s impossible to achieve decent results with this gun, but it’s certainly not recommended. While poor trigger control is usually a common issue with affordable units, it’s still worth mentioning so that you know what to expect. The spray pattern can be quite faint even with highly thinned paint. It’s not a regular occurrence, but make sure you follow the thinning instructions in the user manual in order to avoid such scenarios.

Conclusion


If you’re looking for a good spray gun with decent features, then this model might be a worthy choice. It does have a few drawbacks, but it’s nothing one should be worried about too much. It’s important that you check your compressor’s specifications in order to make sure everything will work fine. In case you don’t have a compressor, make sure to buy an appropriate one for the occasion.

The biggest advantage of this unit is its affordable price. In simpler terms, you won’t get the best thing on the market, but you’ll definitely get your money’s worth.
