They do this 15lb one, and a 40lb unit too... This one was like $70 after a 20% off coupon from HotRod mag.
I put it all together yesterday afternoon, and did some "Blasting" on the intake...
Only had time to do a test section, but it seems to work great.... made a big mess in my garage tho!
Good news is its more grainy than dust, looks like sugar all over the place, but I can vac it up easy.
I have a media blasting cabinet too, so I am off to my storage unit to have a tidy up, and while I am there, I will pull it out and bring that home, so I can contain the mess better!
