The M18™ SWITCH TANK™ 4-Gallon Backpack Water Supply kit delivers the industry�s first interchangeable tank design with no manual pumping. Designed to meet your 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 regulator adjustment knob adjusts the pressure between 20 ‐ 60 PSI for ultimate control. The M18™ REDLITHIUM™ XC3.0 Battery provides you with up to 12 tanks of water delivery per charge. The 4-gallon water supply tank features 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 providing you with 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, while the interchangeable Tank Assembly includes the pump, 10ft hose, and quick-connect. The isolated pump, hose, and quick-connect design allows you to add on tank assemblies for different 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 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. In addition to the backpack water supply, the kit includes one M18™ REDLITHIUM™ XC3.0 Battery and an M18™/M12™ Multi-Voltage Charger.
