The new double-drum series comprises three models, which range in operating weight from 5,510 to 7,720 pounds, in drum widths from 39.4 to 51.2 inches, and in horsepower from 27 to 38. Equipped with a dual-frequency vibration system (3,180 and 3,720 vpm), the models generate centrifugal forces from 4,580 to 8,877 pounds. Estimated list price: $42,700.
