Used for coating repair, coating removal, steel surface preparation and anti-fouling removal, and designed to accept any media heavier than water and has a blast rating of up to 12 bar (175 PSI). Vapor Abrasive blasting is similar to dry blasting, except that the blast media is moistened prior to impacting the surface and creates up to 92% less dust than traditional dry blasting. Because dust is minimized, less containment may be required and media clean-up time can be reduced. The EcoQuip2 blasters use less water than slurry or other water-based blasting technologies, so no pools of water are left behind, and less need to worry about toxic runoff. The end result is a cleaner, more effectively contained process. The EcoQuip2 blasting units are designed for years of safe and solid onboard maintenance.
