Salford's Valmar 9620 is the largest pull type air boom applicator on the market today. n nThe 9620's 660 cubic foot capacity is designed to reduce fill stops and the heavy duty 20 ton walking beam suspension carries the load with confidence at high speed. Capable of applying up to 110 acres per hour, the 72 foot boom helps cover acres quickly as the hydraulic suspension ensures boom stability. The booms can be hydraulically raised and lowered up to 8 feet at the tip, allowing the 9620 to contour the ground for the most accurate application. Prior to leaving the factory, all air booms are factory calibrated and certified to be within +/- 5% of the target application rate on each side of the machine. n nThe 9620's speed, precision, capacity, and value make it an economical replacement for self-propelled air boom units.
