first blast with mine was the box trailer for shake-down run.....and I used a 100 cubic meter capacity, but 10 cfm compressor to run it. while the compressor struggled, it worked well. better than wire-wheeling any way. it also came with an assortment of ceramic nozzles for different types of blasting grit. you can get them at ay chinaman's tools sellers. I got mine from Bowral toolbox. If you hunt around , expect to spend about $500 -1200 for a decent compressor to run it all day
