![]() Some air compressors hover around the 3-5 CFM range. Air compressors can vary wildly when it comes to this metric. Why is this the case exactly? Well, sandblasting works best when you are using an air compressor with a fairly high CFM output. ![]() However, it takes on special importance when trying to find an air compressor for sandblasting. If you have ever used an air compressor before, or if you are familiar with how they work, then you no doubt know what CFM refers to and why it is important.Ĭubic feet per minute is one of the most difficult important things to keep in mind when evaluating any air compressor. Like I’ve said before, air compressors have a lot of features and not all of them are of equal use when it comes to sandblasting. In this section of the article, I’m going to talk about some of the features that you should look for when buying an air compressor specifically for sandblasting. The only complaint I have is sometimes it takes a couple of tries for the Honda engine to get started. I understand that not everyone operates on the same budget, so sometimes you have to make do with sub-optimal tools in the name of making money. Likewise, it is also fairly cheap as far air compressors go. I have used the NorthStar, and while the power output is a slight problem for sandblasting, I also recognize that this is the best option for those who may need a truly portable unit. Motor: 163CC Gas Powered Honda Engine (Approximately 5 HP).This is a relatively small, well-built compact air compressor. The V-shaped cylinder orientation and oversized flywheel design keep the temperature of the unit well under control. It is a gas-powered portable air compressor with a 163CC Honda engine. This isn’t the most powerful compressor around (it only has a power output of around 14 CFM), but it is still a decent option overall.īut the key feature that makes this unit is attractive is its portability. If you are in a jam and need something that is both budget and space-conscious, then you might want to consider giving the NorthStar a try. Review Verdict: The 10HP 120-gallon DXCMH9919910 from Dewalt offers a fine balance between output air volume (CFM), size and price and is our top pick for the air compressor for sandblasting. ![]() The Dewalt that can deliver an output volume of 35 CFM at 100 PSI and a maximum air pressure of 175 PSI is good for most small and medium-duty sandblasting jobs. Here are the best air compressor for sandblasting that I found best for small and medium-size industries including automotive work. A larger diameter nozzle would require a higher volume of air (CFM) to successfully perform its task. Please note that similar to spray painting, sandblasting requires a continuous supply of air, and hence the tank capacity is also important.Īnother factor that many people often overlook is that, with the way sandblasting works, it is very common that the orifice of the nozzle gets worn out and becomes larger. Bigger jobs with #4 nozzle (1/4”) require 80 CFM 100 PSI and heavy-duty jobs the utilize #6 nozzle or more need 175 CFM and above at 90 PSI. For a small sandblasting work that uses #2 nozzle (1/8”), you need an air compressor that can deliver 20 CFM PSI. The size of an air compressor for sandblasting depends on three factors: the nozzle size of the sandblaster, CFM (air volume), and PSI (Air pressure). In this article, I’m going to look at air compressors specifically from the perspective of someone who is primarily going to be doing sandblasting. However, just because it is a common air compressor job, doesn’t mean that every air compressor is equally well-suited to doing said job. The power of the pressurized air allows you to quickly clean, smooth, and shape a wide variety of surfaces. Sanding blasting is the process of utilizing compressed air to hurtle fine abrasive materials such as sand on to the workpiece to remove rust, paint, scales formed by heat treatment, oil and grease stains, etc. Sandblasting, or abrasive blasting as it is often called is one of the more common uses of an air compressor.
