4-Gallon Backpack Sprayer kit delivers the industry’s first interchangeable tank design with no manual pumping. Designed to meet the needs of professional landscape maintenance, the battery-powered backpack sprayer provides you with instant, constant and adjustable pressure up to 120 PSI and a 25 ft spray distance.

5-mode pressure adjustment knob adjusts pressure between 20-120 PSI, delivering the capability to complete a wide range of applications.

The 4-Gallon Sprayer Tank Assembly features a dual-diaphragm pump for longer pump life and Viton® seals for increased durability against harsh chemicals. The sprayer tank has a wide mouth opening for easier pouring and a strainer that filters debris from getting into the tank. The backpack frame includes wide straps giving you added comfort during extended spraying applications and a handle for convenient transport and storage.

The 4-Gallon Sprayer is made up of two components – the M18™ SWITCH TANK™ Powered Base and the SWITCH TANK™ 4-Gallon Sprayer Tank Assembly.
