This CAN be run from 120v but is better on 240.
The next thing is the vacuum unit. DO NOT even consider a cabinet that uses a common vacuum cleaner for evacuation.
You will be buying vacuum cleaners every 2 weeks.
Get a good vacuum unit made for blast cabinets that the motor is seperate from the bag box.

I put a small shop vac on mine, has been used MANY hours, over quite some years. Works as good as the day I put it together. If you are looking for a cabinet blaster, make sure it has the replaceable window panels. If you are looking at a open air blaster, I have a 6HP 22cfm compressor and it has all it can do to keep up. My tip is 3/32, sometimes use 1/8. I like the black slag blast rather than sand for outside blasting. For cabinet blasting I use glass beads. Both of mine are Harbor Freight. Installed a light in the cabinet, gloves are original have worked for 8 years and not ripped yet.
