Dust-free, on-site sandblasting opens up a whole new market to decorative sandblasters. You can now go into a building and sandblast on installed glass, metal or stone without creating a huge mess. This blaster uses a high volume vacuum return to recapture dust and abrasive and to recycle the usable abrasive through the blaster continuously.
This blaster is a siphon system, so it requires a substantial amount of air to operate continuously for long periods of time. If your existing compressor is not adequate, or if it is not portable, renting a larger compressor could be a viable, low-cost option for you to get into on-site blasting.
Many people doing on-site blasting use 2 hp, 110v compressors even though these compressors do not provide enough air to blast for long periods of time. They simply modify their blasting technique to alternate short periods of cutting out the resist with short periods of blasting, instead of doing all the cutting first and then all of the blasting. Some people use two 2 hp compressors to provide a longer period of blasting time before running out of air.
