Keene Engineering's Model 190 series Drywasher & High Banker Dredge Combination is the most advanced and user friendly unit on the planet. With Six Unique Patents to its credit, this series includes Soft Bed Technology which creates a whopping 7 milliamps of constant current, resulting in an electrostatic charge ten times greater than any other drywasher. This unit also creates a positive charge on all dust particles that reacts to the negative charge of the ground, creating virtually a dustless environment.
