D.B Smith Roundup® backpack sprayer maintains constant pressure

• Internal chamber design allows for 50% less pumping effort than conventional backpack sprayers
• Includes high- and low-pressure chambers

This D.B. Smith Roundup® 4-gal. sprayer has the same features as the popular Field King™ model (below), but its internal chamber design requires half as much pumping to maintain a constant pressure. This feature greatly reduces drift and provides a uniform application of chemicals. Includes a low-pressure chamber for spraying herbicides and a high-pressure chamber ideal for extended reach and penetration of insecticides, fungicides and fertilizers. Also includes an 18” polyethylene wand and a foaming nozzle that creates visible foam to avoid overlapping and missing spots while spraying. Includes adjustable brass, flat fan and foaming nozzles. Weighs 10 lbs. USA made.
