Milwaukee M18 SWITCH TANK Backpack Sprayers Milwaukee M18 SWITCH TANK backpack sprayers deliver 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. The 5-mode pressure adjustment knob adjusts the pressure between 20 to 120 psi， giving you the capability to complete a wide range of applications. Milwaukee's M18 REDLITHIUM XC3.0 battery provides you with up to 12 tanks of spraying per charge. 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 isolated pump， hose， and wand design allows you to add on tank assemblies for different spraying applications， eliminating cross-chemical contamination. It also provides you with the ability to replace the tank assembly at a lower cost of ownership compared to replacing the entire sprayer. These units are available with the sprayer only， or in kits with a battery and charger. Required Parts Some required parts are vehicle specific: View All Required Parts
