Best Air Compressors For Sandblasting (7+ Top-Rated in 2024)

Sandblasting can be a necessity when it comes to restoring old metal projects or preparing surfaces for painting. It can remove rust, heat marks, and even paint from any metal surface to give it a new look.

However, you’re going to need a proper air compressor to deliver the optimal air volume to your sand blaster.

I’ll explore the best air compressor for sandblasting, the different types of air compressors, and much more. Let’s dig in!

In a hurry? The best air compressor for sandblasting is the NorthStar 20-Gallon Air Compressor because of its mix of power and affordability.

Quick Answer: Here are My Favorites! 👇

Things to Consider When Purchasing an Air Compressor

When purchasing an air compressor, it’s critical to consider several factors before putting any money down.


Price is the first thing I recommend considering when purchasing an air compressor for sandblasting. Although there are plenty of affordable options out there, the strongest air compressors will cost thousands of dollars.

Well-known brands like DeWalt and CRAFTSMAN make amazing electric air compressors, but they aren’t always the most affordable.

You may also want to look for sale opportunities on more expensive products. Although they don’t happen too often, it’s critical to be ready. Father’s Day, Christmas, and Labor Day are all excellent times to hunt for an air compressor sale.

If you want a quality project, you may need to spend a good chunk of money on a quality air compressor. It’s worth it to spend more now, rather than creating additional expenses if you have to fix a failed sandblasting project.


Another item to consider is the CFM, or cubic feet per minute.

CFM is critical because it can impact the effectiveness of your sandblasting. The lower the CFM, the less air pressure your compressor will produce making it more difficult to get the right air flow for your job.

Air compressors can be all over the place when it comes to this value. It’s critical to remember that just because an air compressor is large does not mean it has a high CFM.

The low end of the CFM spectrum hovers around three to five. You want to aim for at least ten CFM – and even that may not be enough for the most effective job. Ideally, your air compressor of choice should be at least twenty CFM.

Sandblasting requires a high-intensity output of air. The higher the CFM, the more effectively you can get the job done. Don’t settle for anything weaker than ten CFM if you want an easy job.

Gas or Electric

Another item to consider is whether the air compressor is gas or electric.

This can make a big difference when dealing with the operation and maintenance of the machine. There are advantages and disadvantages to both, particularly with sandblasting.

Many people love electric models for a few reasons. They don’t require as much of a cleanup thanks to their lack of fuel. They also cost less, as there is minimal maintenance required. There are no dangerous fumes in the air with an electric-powered air compressor. 

On the other hand, some people prefer gas-powered systems. They might cost more than the electric option, but they are often a more powerful air compressor that will make your job easier. Gas air compressors typically boast high CFM, PSI, and horsepower.

Of course, it’s up to you to determine what you value most in an air compressor. Do you want to gas avoid fumes in the air? Do you want the convenience of just plugging in your air compressor and starting? Or do you want a compressor that offers maximum air pressure and power?

Nozzle Size


Nozzle size is another factor many people overlook when selecting an air compressor for sandblasting.

If you want a high CFM, there needs to be enough room for the air to come out of the tank. The larger the nozzle, the more pressure you will find coming from your compressor.

Here are a few examples of nozzle size and the CFM you can expect:

  • #2 Nozzle: ⅛ inch orifice, 18.5 CFM
  • #3 Nozzle: 1/16-inch orifice, 41 CFM
  • #4 Nozzle: ¼ inch orifice, 74 CFM
  • #5 Nozzle: 5/16-inch orifice, 126 CFM

The pressure continues to rise as the diameter of the nozzle increases.

The more CFM, the better when dealing with a sandblasting project.

It’s critical to determine the size and needs of your work to decide on the minimum CFM necessary for a successful project. Once you have a number, you can determine the air compressor that fits your budget and needs. Nozzle size is often forgotten – but I think it’s vital to success.


If you want to complete a sandblasting project, you need to be ready for a lengthy process. Unfortunately, even if you are prepared, many air compressors are not because of capacity issues.

If your compressor has a low tank capacity, you might find yourself waiting for it to fill back up. This can longer than you’d like if your compressor isn’t powerful.

I think capacity is one of the most critical components of an air compressor, especially when sandblasting.

The higher the capacity, the better off you will be. Of course, it’s critical to note that a high capacity air compressor may not be as portable and they also tend to be more expensive than their counterparts.


Horsepower is another factor many people consider when purchasing an air compressor for sandblasting. It falls in the same ballpark as CFM – without high horsepower, you may have trouble getting the job done. However, many consider CFM to be a better indicator of power than horsepower.

It’s critical to note that horsepower ratings have shifted over time. An older model might look a little different than a newer model in operation, even if they have the same horsepower out of the box.

While horsepower is important, I don’t thinks it’s necessarily a dealbreaker as long as the unit offers a solid CFM rating.

Use Time

How often are you planning on using your air compressor? Will it be something that goes to work several times a year, or will it be a one-time thing? It’s vital to consider your use time to determine which air compressor is worth your money.

The more often you plan on using the air compressor, the higher the duty cycle. If you only plan to use it a few times a week, you can invest in an air compressor option with a 50/50 duty cycle.

Putting thousands of dollars into a tool you will use many, many times will be well worth the investment. If you only want to use it once, get one that will work just well enough to get the project done. There are different price points associated with various uses.

Types of Air Compressors

There are several types of air compressors out there. It can be tricky to tell the difference!

Reciprocating Air Compressor

The first type is the reciprocating air compressor.

This type takes advantage of positive displacement to operate. That process involves taking in air, placing it in a small chamber, then pressurizing the added air. It’s an effective mechanism that works well in an air compressor.

Reciprocating air compressors need a piston to power the process. This tool works to take in the air and compress it before dispelling it for whatever function that’s needed. There are also spring-loaded valves that open when the proper differential presses against them. 

The compression ratio needs to be accurate for a reciprocating air compressor to function properly. If the absolute discharge pressure or absolute intake pressure is too much, there could be an excessive discharge temperature from the imbalance.

Reciprocating air compressors, also known as piston compressors, are one of the most popular styles of compressor used on the market today. You will find most major tool companies with at least one reciprocating air compressor in their lineup.

Single Stage Piston Air Compressor

Next is the single-stage piston air compressor. This variety occurs when a piston only uses one side for the process of compressing air. It might seem like this wouldn’t be ideal, but there are plenty of benefits to a single-stage piston air compressor.

A single-stage air compressor works in a few steps. The air is first drawn into the system. From there, it is compressed with one movement of the piston. The average single-stage piston air compressor can hit up to 150 PSI with this singular motion.

Often, a single-stage piston air compressor allows more CFM than a two-stage air compressor. While it might seem like two is better than one, the utilization of a single side of a piston permits more air to be drawn and compressed with each rotation of the compressor.

Many companies have single-stage piston air compressor options in their lineup. DEWALT is perhaps the most notable with at least four options currently available.

Two Stage Piston Air Compressor

The two-stage piston air compressor is like the single-stage piston air compressor except it uses both sides of the piston to compress air and create power for sandblasting. It typically does not have as much CFM as the single-stage air compressor.

There are two steps to the compression process with a two-stage piston air compressor. The air is brought into the system and pushed into a slightly warmer temperature. Then, the air goes inside an intercooler to cool and is compressed again.

The best two-stage piston air compressors can hit up to 200 PSI. Although many single-stage piston air compressors can hit higher PSIs, two-stage piston air compressors are more effective thanks to the cooling stage in the middle. 

Rotary Air Compressor

Rotary air compressors are another type of positive displacement air compressor. The most common is known as a single-stage helical, which has two rotors in a casing with no piston. These compressors are simple to work on and don’t need much maintenance from the owners. They can go on almost anything that can hold their weight.

Most rotary air compressors work by lowering the air temperature with air or water, allowing the machine to create a continuous form of cooled, pressurized air. It’s an effective and portable system.

You can pick a rotary air compressor without oil or with oil. There are benefits and disadvantages to both choices. Oil-based options are very efficient, but they require more maintenance and cleanup as you use it. Oil-free is less work for you.

Centrifugal Air Compressor

A centrifugal air compressor is what is known as a dynamic air compressor. They are an oil-free option on the market, designed for minimal maintenance. Centrifugal air compressors work by changing the direction and pressure of the air.

This type of compressor works continuously. They only have a few parts that move, so they’re excellent for high-volume situations – especially oil-free choices.

Most of the time you will find centrifugal air compressors in a professional, industrial situations. They have a higher flow rate and stronger horsepower than other air compressors on the market. These factors mean it’s more expensive to purchase a centrifugal air compressor and nearly impossible to locate at small hardware stores.

Centrifugal air compressors are designed and built for massive projects. Unless you work in a large shop, it’s not the right choice for your sandblasting project.

Safety Tips for Sandblasting with a Compressor 

It’s critical to stay safe when sandblasting with your air compressor. Even if you feel like an expert, safety should still be at the forefront of your mind.

Keep the Environment Safe

It’s critical to consider your environment when sandblasting. You may be working on one project, but you can’t forget about what’s around you.

When thinking about the environment, you should consider the following:

  • Getting rid of falling hazards: If there is anything on the floor you could fall over, remove it. You don’t want to slip as you’re sandblasting.
  • Creating a working blasting space: Ensure everything is in working order before beginning the process. Create ventilation and check all working components.

When you sandblast, it’s critical to ensure you have the safest environment to prevent injuries and potential damage to your workspace and project.

Wear Protective Gear

Protective gear is a must for sandblasting with an air compressor to protect from toxins and particles shifting through the air. If you don’t take on protective gear, there is a chance you could suffer internal or external injuries.

Here are two forms of protective gear you should have:

  • Protective garments: There needs to be gloves, helmets, clothing, footwear, and protective eyewear to make sandblasting as safe as possible.
  • Respiratory equipment: Workers need a respirator that covers the head, neck, and shoulders. Anything less would expose them to dangerous toxins.

Examine your protective gear before and after every use to determine if there is any surface damage. If there is, repair or replace the product as soon as possible to stay safe on the job.

Examine Equipment First

It’s vital to examine the equipment before beginning sandblasting. If there is something out of place, it needs to be addressed as soon as possible for the safety of you and everyone around you.

Here are a few ways to keep your equipment in check:

  • Examine the blast hose: Check for any leaks or cracks that may have appeared in the hose.
  • Test carbon monoxide and breathing filter items: Ensure all filtration systems prevent breathing in toxic fumes.
  • Try non or less-toxic abrasives: Go for abrasive choices that don’t have as many toxins inside to prevent excessive exposure. 
  • Check for damage: Ensure your equipment is free from damage ahead of time, such as cracks or leaks.

Sandblasting can be a dangerous task if you don’t take the proper precautions. I always going through these safety steps to ensure everything goes as smoothly as possible.

Cleanup Properly

It’s critical to clean up after the sandblasting process to remove dangerous chemicals from your space.

Here are a few things to consider for proper cleanup:

  • Don’t use concentrated air methods: Avoid compressed air. It will dispel dust in the air and cause dangerous breathing conditions.
  • Clean the location with water: Use a HEPA vacuuming system and water-based tools to clean up the results of sandblasting.

Purchase Wisely

Finally, it’s critical to purchase wisely. Find an air compressor that fits your area so you don’t end up tripping over it.

You should also take care of protective equipment. Purchase quality items to keep yourself safe and out of harms way.

How To Maintain Your Compressor

Like any tool, you need to maintain your compressor to keep it in quality shape over time. It isn’t too tricky to maintain the tool – all it takes is a little work after several uses.

Ensure you examine the user manual to determine the specific directions for your compressor. From there, ensure the machine has proper lubrication to work properly. Run clean air through the system after every use to ensure there are no blockages that could lead to further damage.

The more money you spend on your compressor, the more critical it is to maintain the tool.

Final Thoughts on the Best Air Compressor for Sandblasting

When it comes to choosing the right air compressor for sandblasting, there are a few things you’ll want to consider: the price, the capacity, and the CFM rating.

Ultimately, I recommend the Northstar 20-Gallon Portable Compressor for sandblasting thanks to its medium capacity tank, portability, and overall power. It’s a great compressor for the money.

If you want something a little less expensive, I recommend the DEWALT Pancake Compressor. It’s an affordable option that’s still very high quality.
