? Internal chamber design requires 50% less effort than conventional backpack sprayers
? Excellent for controlling drift

This 4-gallon sprayer has the same features as the FKS4 model, but with an internal chamber design that requires half as much pumping to maintain a constant pressure when spraying herbicides or other liquids. This greatly reduces drift and provides a uniform application of chemicals. Some additional features on this model are a flexible polyethylene wand and a foaming nozzle that creates visible foam to avoid missing spots and overlapping. Includes adjustable brass, flat fan and foaming nozzle. Weighs 10 lbs. USA made.
