Blastrac 220-DTMKII Shot Blaster


The Blastrac® 2-20DTMKII is a powerful self-propelled 20” shot blasting system, ideal for medium to larger sized jobs. Whether improving traction and skid resistance or prepping for coatings and overlays, the versatile 2-20DTMKII strips, cleans and profiles concrete and asphalt, or horizontal steel surfaces in one easy step.

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-99 or other suitable Blastrac dust collector, it operates virtually dust-free. A slide-out screen in the shot hopper facilitates the removal of large debris.

The 2-20DTMKII can prepare up to 4850 sq. ft. per hour consuming abrasive at about 1.6 lb. per 100 sq. ft. or 78 lb. per hr. The quick-lift rear caster assembly makes this 1268 lb. unit easily transportable. It has highly visible and manageable controls with the drive control on the steering handle. The 2-20DTMKII operates on 460V, three-phase, and all electrical components and panels are UL certified, part of the Blastrac commitment to safety protocol.

Perfect for industrial floors, warehouses, road and airport maintenance, and parking garages, this shot blaster is an environmentally sound choice for high productivity in surface preparation.
