The Blastrac 2-20D (Circle 918) electric shot blast cleaning system from International Surface Preparation, Bellaire, Texas, produces a 20-in. blast pattern to strip, clean and profile concrete or steel surfaces in a single step. The 2-20D system uses 460 V, 3-phase, 60-Hz power, and is designed for medium- to large-sized jobs such as highway or bridge work, airport runways and tarmacs, parking garages and other surface preparation applications. The 2-20D uses two side-by-side blast wheels that are positioned to ensure an even pattern. Twin 15-hp motors provide plenty of shot-throwing power, and a self-propelled drive system with integrated brake is designed to handle ramps and inclines, allowing for consistent travel speed.
