The latest in surface blasting equipment would be Graco’s EcoQuip 2, the newest technology in vapor abrasive blasting. This equipment precisely injects moist abrasive into the blast stream, which can suppress dust levels up to 92%. This is not to be confused with slurry blasting, which is blasting with slurry of air, water and abrasives that ends up wasting too much water and abrasive and creating a significant pool of contaminated water that is difficult to contain and dispose of.
