I probably get 100 people asking me questions a year about finding the right air compressor for their pressure pot sandblaster so I decided to post the chart here. This chart was pulled straight from the bonus section of my downloadable sandblaster plans manual.
You can buy my information plans if you’d like more detailed information on this subject or you can just leave a question below.
One of the first things you need to do is figure out what size nozzle you will want to use. The bigger the nozzle, the larger more powerful of an air compressor you will need. The most important rating you need to look at when buying a air compressor is the SCFM which is an abbreviation for Standard Cubic Feet per Minute.
Once you pick a nozzle size that you will be using most of the time, go to the next larger size up to find the minimum SCFM you will need. This is suggested because the nozzle will wear out in little time.
Then all you need to do is match up a air compressor with the SCFM rating stated in the box for a desired PSI rating.
