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.

Select from ceramic or various carbides. Large C1 sizes & regular C2 sizes
Going by that chart I’ll have to use a tiny nozzle or forget about blast cleaning stuff
Do you have any info on modifications to pressure pot delivery system for soda blasting?
I can’t afford the Eastwood conversion ($135.00+)
I need to clean some zinc alloy motorcycle carburetors and various other bits (1970’s Honda’s and Yamaha’s)

Peter, thanks for posting in. Sorry, but I dont have any modifications for soda blasters. You might just want to buy a separate soda blaster and keep your pressure pot for the heavier stuff.
Harbor Freight has a small one. I just looked at it and its more expensive than I thought it would be. About 100 dollars. Its cheaper than a conversion though.
This is a question not a comment.
Most blaster need a lot of air. I only have a small air compressor.
My question is : Can you put two air compressor together. I’ve seen videos on
youtube. Some people say YES and others NO. Can you clearify it for me!!!
Thank you for your time.
