Has anyone used one? I have a job that they want some Stainless tanks blasted to a uniform finish. This is a multimillion dollar project so they are pretty specific on what they want. They want it blasted, they do not want any dust, and it has to be done next week. I just quoted them $9,000 for 800 sq. ft. that includes blaster($1500), shipping of blaster($1,100), and 750cfm compressor rental($900) and I made the rate 170/hr. which includes media(glass bead), fuel, and consumables. We are figuring about 32/hrs. of blasting @25 sq. ft. an hr. This unit requires no cleanup after and re-uses the media as it goes. Any thought?
