Birchmeier closed system

Birchmeier Closed System Backpack Sprayer.

his unique, Birchmeier closed-system backpack sprayer draws pre-mixed spray material from a 2.5-gal. container that fits right inside the sprayer tank. This allows the user to pre-mix all chemicals before going to the field. Sprayer has the same features as the standard Birchmeier backpack sprayers, including 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 dri’. Lid features a quick disconnect so you can quickly change containers. Includes one 2.5-gal container. Made in Switzerland.
