Description

As published by Beyond Tools

The M18™ SWITCH TANK™ 15 Litre Backpack Water Supply with Powered Base offers an easy-to-use 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 dial allows the operator to adjust the pressure between 20 – 60 PSI for control in dust suppression. Paired with an M18™ REDLITHIUM™ 5.0Ah Battery (sold separately), the unit can discharge up to 60 tanks of water on Mode 5. The 15 Litre Water Supply Tank features a dual diaphragm pump for increased durability and longer pump life. The tank also has a wide mouth opening for easy fill and pour, and a strainer to filters debris from entering the tank. The Backpack Powered Base includes a premium adjustable harness and a handle, providing convenient transportation and storage. The 15 Litre Water Supply is made up of two components, the M18™ SWITCH TANK™ Powered Base and the SWITCH TANK™ 15 Litre Water Supply Tank Assembly (491619WS). The Powered Base includes the motor, battery compartment, and REDLINK™ electronics, while the interchangeable Tank Assembly includes the pump, 3 metre hose, and quick-connect coupler. The isolated pump, hose, and tank allows users to add on additional tank assemblies for different applications. The M18 Powered Base is also compatible with the 15 Litre Chemical Sprayer Tank Assembly (491619PS).
