The Milwaukee M18 SWITCH TANK 4 Gallon backpack water supply kit is the industrys first interchangeable tank design with no manual pumping. Designed to meet water supply needs for concrete cutting and coring, the battery-powered water supply delivers instant, constant and adjustable pressure up to 60 PSI. The 5-mode pressure adjustment knob adjusts the pressure between 20 60 PSI for ultimate control. The M18 REDLITHIUM XC3.0 battery provides up to 12 tanks of water delivery per charge. The 4 Gallon water supply tank assembly has a dual diaphragm pump for increased durability and longer pump life. The tank also 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 and a handle for convenient transportation and storage. The 4 Gallon water supply is made up of two components the M18 SWITCH TANK powered base and the SWITCH TANK 4 Gallon water supply tank assembly. The powered base includes the motor, battery compartment, and REDLINK electronics. The interchangeable tank assembly includes the pump, 10 ft hose, and quick-connect. The isolated pump, hose, and quick-connect design allows tank assemblies to be added for different applications, eliminating cross-chemical contamination. It also allows tank assemblies to be replaced at a lower cost of ownership compared to replacing the entire water supply. The powered base is also compatible with the SWITCH TANK 4 Gallon concrete sprayer (49-16-28CS) and 4 Gallon sprayer (49-16-28PS) tank assemblies. The M18 SWITCH TANK 4 Gallon backpack water supply is part of the M18 system which is fully compatible with over 175 tools. The kit also includes one M18 REDLITHIUM XC3.0 battery and an M18/M12 multi-voltage charger.
