Better make sure you gotta compressor big enough to handle the blaster...I gotta 30 gallon with a 20 gallon tank piped into that for more capacity and it still continuously ran my compressor when I used the blast cabinet.
I just didn't wanna wire up a 220 outlet and buy a 80 gallon compressor...kinda pricey too..I would have to blast for a bit, wait til the compressor built back up when the sand wasn't cutting anything anymore, and repeat til it was done. I got tired of blasting so much, i went to manually stripping first, then blasting the bare metal for better adhesion of my powder coat.
