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.
