Best Air Compressor for Sandblasting and Industrial Jobs

The use of air compressors is diverse, ranging from spray painting ­­to abrasive blasting, and almost every sector makes use of them. The more common uses of these compressors include divers who need an air compressor tank to go on deep diving. But different compressors do different things, which is why you'll need the best air compressor for sandblasting that is suited for abrasive blasting because it too requires some specifications.

What is Sandblasting?

Sandblasting, also known as abrasive blasting, is one of the more common uses of an air compressor. Sandblasting is the process where you utilize compressed air to zap fine abrasive contents such as sand onto a workpiece to remove paint, rust, oil and grease stains, scales formed by heat treatment, etc. The power of the compressed air pressure quickly cleans, smoothens out, and even shapes various surfaces.

However, as pointed out, just because it's a common use of air compressors doesn’t mean that every air compressor is best suited for the job. When specifically looking at sandblasting, the size of an air compressor will depend on 3 factors: the sandblaster nozzle size, PSI (Air pressure), and CFM (air volume).

With that in mind, let's dive into the different air compressors for sandblasting that are best suited for the job.

Buying Guide for the Best Air Compressor for Sandblasting

A) CFM

If you've used an air compressor before, or are familiar with how it works, then no doubt you know what CFM rating refers to and why it's crucial. The CFM is one of the most important technical things you'll have to keep in mind as you evaluate what air compressor you want you to get. Sandblasting works best when you are using an air compressor with a fairly high CFM rating output.

Air compressors will vary wildly in this metric. Some air compressors will hover around the 3-5 CFM range. These are good enough for some activities such as nailing; however, for sandblasting, you'll want a sandblasting air compressor with a minimum of 10 CFM. Ideally, you'll find ones that go up to 20 CFM.

Overall, sandblasting is highly intense, so using an air compressor with a high CFM is vital.

B) Nozzle Size

The CFM rating will also depend on the diameter of the nozzle's orifice. The larger the nozzle hole diameter, the more the volume of air and air pressure capacity needed.

C) Electric or Gas

Like most power tools in the market, you will have to choose whether you want to go with a gas-powered air compressor sandblaster or an electric model. Electric air compressors have their advantages, including the cost and the convenience they come with, which include; no need to buy gas, no fumes, and relatively lower maintenance costs involved.

On the other hand, gas air compressors are generally a much better option when you need portable sandblasting. These gas air compressors are pricier, but they also come with a lot more power in the form of a higher CFM, PSI, and horsepower.

Frequently Asked Questions on the Best Air Compressor for Sandblasting

1. What air compressor size will I need for sandblasting?

For small sandblasting jobs that use a #2 nozzle (1/8-inch), you will need an air compressor to give a blasting pressure of 20 CFM at 100 PSI. Bigger sandblasting jobs with a #4 nozzle (1/4-inch) will require blasting pressure that's at least 80 CFM at 100 PSI. Lastly, heavy-duty sandblasting jobs that use a #6 nozzle or more will need at least 175 CFM and above at 90 PSI.

2. What is the difference between SCFM and CFM?

CFM in full is Cubic Feet per Minute, whereas SCFM in full is Standard Cubic Feet per Minute. CFM is calculated at a higher pressure than SCFM, making the air volume smaller and, therefore, always a smaller number than the SCFM.

3. How do you combine 2 air compressors?

To connect 2 compressors, simply plug each airline into each air compressor's coupler and then connect the 2 airlines using a Tee. Of course, these 2 airlines can also be shortened depending on personal preference.
