Milwaukee 2820-21CS M18 SWITCH TANK 4-Gallon Backpack Concrete Sprayer Kit

The M18 SWITCH TANK 4-Gallon Backpack Concrete Sprayer kit brings the industry’s first interchangeable tank design with no manual pumping. Built to meet the needs of concrete contractors, this battery-powered concrete sprayer gives instant, constant, and adjustable pressure up to 120 PSI and a 25 ft spray distance. A 5-mode pressure adjustment knob sets the pressure between 20 – 120 PSI, so you can complete a wide range of applications. The M18 REDLITHIUM XC3.0 Battery gives you up to 12 tanks of spraying per charge. The 4-Gallon Concrete Sprayer Tank Assembly has a dual diaphragm pump for longer pump life and Viton seals for more durability against harsh chemicals. The tank also has a wide mouth opening for easier pouring and a strainer that keeps debris out of the tank. Wide straps on the backpack frame add comfort during extended spraying, and a handle allows convenient transport and storage. The 4-Gallon Concrete Sprayer has two components: the M18 SWITCH TANK Powered Base and the SWITCH TANK 4-Gallon Concrete Sprayer Tank Assembly. The Powered Base holds the motor, battery compartment, and REDLINK electronics, while the interchangeable Tank Assembly holds the pump, hose, and wand. Because the pump, hose, and wand are isolated, you can add tank assemblies for different applications and eliminate cross-chemical contamination. It also lets you replace the tank assembly at a lower cost of ownership than replacing the entire sprayer. The Powered Base also works with the SWITCH TANK 4-Gallon Sprayer (49-16-28PS) and 4-Gallon Water Supply (49-16-28WS) Tank Assemblies. The M18 SWITCH TANK 4-Gallon Backpack Concrete Sprayer is part of the M18 system, which is fully compatible with over 175 tools. Along with the backpack concrete sprayer, the kit includes one M18 REDLITHIUM XC3.0 Battery and an M18/M12 Multi-Voltage Charger.
