Birchmeier Closed System Backpack Sprayer

This closed system backpack sprayer draws pre-mixed spray material from a 2.5-gallon container that fits inside the tank, allowing you to pre-mix chemicals before going to the field. The lid features a quick disconnect so that you can quickly change containers. Features an externally mounted pump, brass cylinder, brass shutoff valve, and external cylinder lubrication. Maximum pressure is less than most backpack sprayers at 40 psi, but is ideal for herbicide applications and reducing spray drift.
