Ideal for medium to larger sized jobs, the Blastrac 1-15DSGI is a versatile, self-propelled 15-inch shot blasting system. 1-15DSGI strips, cleans and profiles concrete and asphalt in one easy step. Whether improving traction and skid resistance or prepping for coatings and overlays, this unit serves the purpose well with its friendly-to-the-environment process. The AC inverted drive-motor for self-propelled operation features an integrated brake which helps maintain speed on ramps and inclines. This improves productivity and promotes a more even and consistent blast pattern and surface profile. Attached to the BDC-66 dust collectors, it operates virtually dust-free containing debris and contaminants for a safer work environment and improved productivity. A slide-out screen in the shot hopper facilitates the removal of large debris.
