Air Compressor for Sandblasting

Sandblasting is one of the common uses of air compressors. Sandblasting is a process in which compressed air is used to impact abrasive materials such as fine sand on the workpiece to remove paint, rust, oxide scale, grease, and oil stains. The power of compressed air allows you to quickly clean, smooth, and shape surfaces.

However, just because it doesn’t mean every air compressor is equally suitable for the job. In this article, we’ll look specifically at air compressors from the perspective of someone who primarily works in sandblasting. We hope this article helped you learn more about sandblasting and find the best air compressor for your needs.


Important factors to consider when purchasing an air compressor for sandblasting

When it comes to sandblasting, the air compressor is a vital piece of equipment. If you are considering purchasing an air compressor for your sandblasting project, there are some important factors to keep in mind.

Compressor type

The type of compressor you need depends on the specific sandblasting project. For example, portable air compressors are great for small one-time projects, like removing paint from furniture. However, if you plan to use the air compressor for more industrial applications, a stationary installation air compressor will be a better investment.

Compressor size

The size of the compressor is just as important as the type. Units that are too small will not provide the power needed for blasting, while units that are too large are more expensive to run and can be difficult to transport. The best way to determine the ideal size for your needs is to consult a sandblasting professional.

Tank size

Another important factor to consider when choosing an air compressor for sandblasting is tank size. The larger the tank, the more air the compressor can store and the longer it can run before it needs to be refilled. Therefore, you will need a compressor with a larger tank to avoid frequent stops and starts for large sandblasting project.


Another important factor to consider when choosing an air compressor for a sandblasting project is horsepower. The higher the compressor’s power rating, the more powerful it is. If you are working on a sizeable sandblasting project, you will need a compressor with a higher horsepower rating to get the job done efficiently and quickly.

Pressure rating

Air compressor pressure ratings are expressed in pounds per square inch (PSI). The higher the PSI, the more powerful the unit. For blasting applications, you will need an air compressor rated at least 90 PSI.


Airflow rate in cubic feet per minute (CFM). The higher the CFM, the more power the device has. For sandblasting applications, you will require an air compressor with a minimum 9 CFM flow rate.


Portability is an important factor to consider if you have plans to use your air compressor for blasting projects at different job sites. Some air compressors are designed to be portable, while others are not. If you need a portable air compressor, choose one with wheels and handles for easy transport.

Noise level

Another factor to consider when choosing an air compressor for sandblasting is noise level. Some air compressors are louder than others, and if you work in a sensitive area, such as near a residential area, you’ll want to choose the quietest air compressor.


Of course, the cost is always an important factor to consider when choosing any equipment. Air compressors for sandblasting projects vary in price, so it’s important to choose an air compressor that fits your budget.

Maintenance Requirements

All air compressors require essential maintenance, such as regular oil and filter changes. However, some units are easier to maintain than others. If you don’t want to spend too much time and money on maintenance, look for an air compressor with a simple design and few moving parts.


Finally, consider the warranty when choosing an air compressor for sandblasting. Some manufacturers offer more extended warranties than others, so it’s essential to find one that provides a warranty that meets your needs. BISON provides one-year warranty service and lifetime technical support.

air compressor for sandblasting FAQs

This depends on several factors, such as the type and size of the sandblaster, how fast you’ll be using it, and the pressure you’ll be operating at.

In general, you need 3 to 15 CFM to operate a sandblaster effectively. The bigger the sandblaster, the more powerful it is, and you’re probably on the high end of the range. If you use the blaster for light sanding work or infrequent use, you can get close to 3 CFM; however, if you use the sandblaster for heavier work, then 15 CFM.

The amount of PSI required for sandblasting can vary based on a number of factors, such as the type of blasting machine used, the type of media used, and the desired results. However, most experts agree that a PSI of at least 80 is required for any sandblasting project.

An air compressor first draws in air from the surroundings and then compresses it. A piston in an air compressor compresses air. The piston is connected to a crankshaft that is turned by an electric motor. As the piston moves up and down, it compresses the air inside the cylinder.

The compressed air is then sent to the sandblasting equipment through a hose. The air compressor powers the operation of the sandblasting equipment. Air compressors are an important part of the sandblasting process and help ensure the equipment is working properly.

SCFM stands for standard cubic feet per minute, whereas CFM stands for cubic feet per minute. CFM is calculated at a higher pressure than SCFM, making the air volume smaller and, therefore, always smaller than SCFM.

To connect 2 compressors, plug each airline into the coupler of each air compressor, then use a T-connector to connect the 2 airlines. Of course, these 2 airlines can also be shortened according to personal preference.

Sandblasting with an air compressor is a relatively simple process, but you will need some preparation. Here, we’ll walk you through the steps of sandblasting with an air compressor so you can start your project.

  1. Choose the right air compressor for your project. If blasting large areas, you will require a high CFM air compressor. For smaller projects, a lower CFM air compressor will suffice.
  2. Set up your air compressor according to the manufacturer’s instructions. This usually involves connecting an air hose to the compressor and plugging the compressor into the outlet.
  3. Connect the blast gun to the air compressor. Most blast guns have a universal connector that fits most air hoses.
  4. Fill the blast gun with sand. Pour sand into the gun until it is about half full.
  5. Put on your safety gear. Sandblasting can be dangerous, so it’s important to wear protective clothing, including goggles, masks, and gloves.
  6. Point the blast gun at the surface you want to clean. Press the trigger to start the blasting process.
  7. Move the gun back and forth while blasting. Again, you’ll want to hold the gun about 6 inches from the surface for best results.
  8. After blasting, turn off the air compressor and disconnect all hoses and wires. Empty any remaining sand from the gun and clear the work area.

Follow these steps, and you will be able to blast quickly and easily with an air compressor. Be sure to take all necessary safety precautions to avoid injury.
