Sandblasting, also known as abrasive blasting, is a technique for surface finishing. The sandblasting machine forces out abrasive particles under high pressure to blast whatever is on the surface, off. It creates a smoother texture and evens it out as well.
For sandblasting, choose an air compressor with a CFM of at least 10-20 and a PSI of 90-100. A smaller machine with a lower CFM (2-6) works fine for small jobs, and CFMs of 35 or above are perfect for heavy-duty or industrial work.
Overall, the Central Pneumatic 30 Gallon is the best air compressor for sandblasting. While it is not as powerful as the Industrial Air unit, it is powerful enough and yet very affordable. With an ideal sandblasting CFM range of 18-19.5 and a maximum PSI of 180, you’ve got the best in terms of power and performance. A good alternative is the Ingersoll Rand SS3J5.5GH.

Other Blasting Applications
Of course, sandblasting is just one use for air compressors.
Soda blasting is a type of abrasive blasting that utilizes sodium bicarbonate (or baking soda) instead of sand. Most air compressors that work for sandblasting are also sufficient for soda blasting.
The Quincy QT-54 is an excellent choice, as is the Ingersoll Rand Electric Stationary Air Compressor. With 5 HP and a CFM of 18 at 90 PSI, this 60-gallon model is perfect for your soda blasting needs.
Vapor blasting uses a mixture of compressed air, water, and gentle detergents to help remove corrosion and oxidized metal. You typically need a compressor with a bit less power, since this process is gentler.
Look for a model with around 15 CFM and 40-60 PSI. The Central Pneumatic 30 Gallon 420cc Truck Bed Air Compressor works, as does the Campbell Hausfeld 5-HP 80-Gallon Two-Stage Air Compressor. It offers 12 CFM at 90 PSI, reduced noise, and a pump life of up to 5,000 hours.
How Does A Sandblaster Work?
In order to choose the right size compressor for your sandblaster, you should know how they work. There are actually a few types of sandblasters available and each one provides air in different ways:
These sandblasters have two hoses. When the air flows through the first hose, pressure is created and sand is pulled from a tank through the other hose. The air and sand then are released together through the gun.
This gun is connected directly to a canister that contains sand. The air and sand are then blown through the canister and gun at the same time.
This sandblaster has a hopper on top of a pressure gun. The hopper will open when it senses the compressed air and the air being pulled will allow sand to be drawn through the hopper and out of the barrel along with air.
Nozzle Size & Pressure
The key to figuring out what size air compressor you need is to know what size sandblast nozzle you are going to use along with the pressure you’re going to need.
If your nozzle has a larger opening and higher pressure coming from it, you will need more air from the compressor.
Once you have determined the size of the nozzle, you will then need to acquire CFM information. CFM stands for cubic feet per minute and it’s essentially the speed at which air leaves the compressor.
If your air compressor has a higher CFM rating, it means that more compressed air is going to come out at the desired PSI. If you are operating a sandblaster that has a high air volume requirement, you need a compressor with both a high CFM and PSI rating.
Additionally, different nozzles will require different CFM standards, but most are in the 2.6 CFM range. Once you know the CFM, a good rule of thumb is to have an additional 30% to 50% compressor capacity.
There are many individuals who choose to use a low-duty compressor that has low demands. If this is an option you are looking for, then you may want to take a look at a two-stage compressor rather than a rotary. Rotary compressors constantly run, but they become more of an inconvenience if it’s not operating consistently.
In terms of PSI, you should use a tank that disperses a minimum of 100 PSI for maximum efficiency. If your compressor has a low PSI, you are going to spend more time on the project than you want to because it’s going to reduce your blasting pressure by half. It may even increase your project time by four times.
CFM and horsepower go hand-in-hand. The more horsepower a compressor has, the higher the CFM will be. This is another consideration that you need to make when choosing an air compressor for sandblasting.
Make sure you take a look at voltage type as well when choosing an air compressor. If the voltage on the compressor doesn’t match the voltage from the power source, the compressor is going to be a dud.
Single-stage compressors will utilize a standard power supply that is found in homes, apartments, and even smaller businesses.
f you don’t have another choice for a power supply, then a single-stage compressor would work, but it does come with restrictions. Single-stage compressors can only go up to 7.5 HP. If you need a stronger motor than that, you may have to look at a three-phase compressor.
Three-phase units are more commonly found in commercial or industrial applications. These are more efficient and bring smoother power, but it costs a pretty penny to install than a traditional compressor would out of the box. However, if your building already has a three-phase power hookup, then this type of compressor would work well.
As you can see, there are a ton of considerations you have to make before choosing the right air compressor for sandblasting.
You really need to think about the CFM rating, size of the nozzle, PSI, and HP ratings. Without the right compressor for the job, you aren’t going to receive the best performance.
