The 10 Best Air Compressors for Sandblasting

Sandblasting has been used to clean tough surfaces for hundreds of years. Whether it be wood, metal, glass, stone or plastic, you can use the abrasive quality of sand particles to effectively and efficiently remove dirt and residue.

Sandblasting can even alter the finish of tough surfaces if so desired, by removing scratches or casting marks.

A rusty garage door can be tackled in no time with the help of a home sandblaster.

However, buy the wrong air compressor to power your machine and you could end up with a new sandpit on your front lawn, but still have as rusty a garage door as ever!

The force that an air compressor creates is what gives the sandblaster its blast! There are plenty of great options out there but it is difficult to know which one to buy.

That’s why we have put together this list of the 10 best air compressors for sandblasting, as well as a buyer’s guide to help you know what elements to look out for when making your choice.

Despite its small size this air compressor has an output volume of 2.6 CFM when delivering 90 psi, which is ideal for small sandblasting tasks.

It allows for a smaller nozzle so you can optimize the pressure and volume, and has a maximum psi of 165, so for intensive sandblasting you can switch to the high-flow regulator option and enjoy a speedier performance.

What’s more, this machine has noise-reducing ability with a noise level of 75.5 dBA, making it a much quieter machine than most, so you won’t get complaints from the neighbors!

PORTER-CABLE Air Compressor

It has a maximum of 150 psi, with 2.6 CFM at 90 psi, which is perfect for light sandblasting projects, and the 6-gallon tank is ideal for small jobs.

The low Amp 120V motor starts easily, no matter how cold the weather, and the whole thing weighs only 30 lbs so it is light and liftable.

The strong motor means that it is an effective and powerful compressor that can tackle small to medium-sized sandblasting tasks like stripping a surface of rust and grease.

Although it isn’t the quietest product on our list, the Makita Big Bore isn’t as loud as other engines of its strength due to its low RPM.

At 6 gallons of capacity, you would usually be restricted to small jobs, but the high psi of 150 means that this product is actually capable of taking on tough surfaces, too.

The whole compressor is made of high quality – the motor and pump are durable and reliable, and you don’t even have to oil the pump, so it is very low maintenance.

Buyer’s Guide

We hope that you found our selection of the 10 best air compressors for sandblasting helpful, but if you still want to shop around, here is a buyer’s guide that will show you all the key components to look out for when making your pick.

CFM

CFM (for those who don’t know) stands for Cubic Feet per Minute and refers to air volume and flow.

For small sandblasting jobs on delicate surfaces and small areas you can get away with around 2-4 CFM of volume from your air compressor. However, for more intensive jobs and tougher surfaces you are better off looking for 6-9 CFM.

And for most hefty sandblasting work, or anything on an industrial scale, you will need an air compressor with at least 10 CFM. Ideally you would want one that goes up to 20 CFM.

Nozzle Size

The larger the nozzle hole on your sandblaster, the greater the CFM your air compressor will require.

For this reason, you should be sure to measure the diameter of your nozzle hole and select an air compressor with the appropriate CFM for its size.

Electric or Gas

As with any power tools, there are pros and cons to both gas and electric air compressors and the final decision really depends on what you are using it for.

Electric models are generally cheaper and easier to use since you don’t need to worry about as many maintenance costs, fumes, or running out of gas.

However, for big sandblasting projects, gas air compressors are arguably the better option.

Although they are pricier, they tend to have more power in the form of higher CFM, psi and horsepower, so you will be able to blast more quickly and effectively.

What’s more, gas models offer greater portability as you aren’t restricted by a power cord – however their tank capacity can be smaller as a result.

Capacity

On that subject… Much like painting, sandblasting tends to be quite a time-consuming task.

As you are likely to be at it for some time, you need a tank capacity on your air compressor that can keep going until the job is done and not cut out while you are only halfway through!

There is nothing worse than having to halt a job time and again to refill the tank, so look for 6+ gallon tanks for small tasks, 20+ for medium tasks, and anything over 60 for hefty tasks. Industrial sandblasting may require 120 gallons or over.

Safety

There are always risks when using an air compressor, and for that reason, you should always read the safety information thoroughly before getting started. When using an air compressor for sandblasting you should try to do it in as wide and open a space as possible, and always wear safety goggles. Plus, try to clear up dust shavings and debris as you work, or else they can really build up and cause issues.
