Simplicity, safety, reliability and performance—those were the design goals when Empire engineered SuperBlast® portables. Many years on tough jobs, such as removing corrosion, preparing surfaces for coating and maintaining heavy equipment, have proved that SuperBlast® portables deliver exceptional value in the field. SuperBlast portables are available in three sizes with 3.5, 6.5 and 10.5 cu. ft. media capacities. All three models, designated as “350,” “650” and “1050” respectively, can be purchased with either 680 (pressure release) or 780 (pressure hold) remote control systems.
