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-speed pressure adjustment knob adjusts the pressure between 20 – 60 PSI for ultimate user control. The 15 Litre Water Supply Tank Assembly features a dual diaphragm pump for increased durability and maximum pump life. The tank also has a wide mouth opening for easy pouring and a strainer that filters out debris from entering the tank. The backpack frame includes wide straps and a handle for convenient transportation and storage. The 15 Litre Water Supply is comprised of two components – the SWITCH TANK Powered Base and the SWITCH TANK 15 Litre Water Supply Tank Assembly. The Powered Base includes the motor, battery compartment and REDLINK PLUS intelligence, while the interchangeable Tank Assembly includes the pump and 3 m hose with quick-connect. The isolated pump and hose design allows users to add on tank assemblies for different applications, eliminating cross-chemical contamination. It also provides users the ability to replace the tank assembly at a lower cost of ownership compared to replacing the entire water supply unit. The Powered Base is also compatible with the 15 Litre Chemical Sprayer Tank Assembly (491628PSA). This is a Skin/Tool Only. Batteries & Charger are Not Included.
