The Milwaukee M18 SWITCH TANK 4-gallon backpack concrete sprayer features an interchangeable tank design with separate powered base and sprayer tank assembly. Designed to meet the needs of concrete professionals, this battery-powered backpack sprayer delivers instant, constant and adjustable pressure up to 25'. Say goodbye to manual pumping!

The 4-gallon concrete sprayer tank assembly features a dual diaphragm pump and Viton seals for increased durability against harsh chemicals. The sprayer tank has a wide mouth opening for easier pouring and a strainer that filters debris from getting into the tank. The backpack frame has wide, comfortable straps and a transport handle.

The five-mode pressure control knob adjusts between 20 and 120 PSI, giving you the capability to complete a wide range of applications. When paired with an M18 REDLITHIUM XC3.0 battery, the SWITCH TANK can spray up to 12 tanks per charge.

This backpack sprayer is made up of two components: the M18 SWITCH TANK powered base and the concrete sprayer tank assembly. The powered base includes the motor, battery compartment, and REDLINK electronics, while the interchangeable tank assembly includes the pump, hose and wand. Because the pump, hose, and wand is separate, you can add on tank assemblies for different spraying applications, eliminating cross-chemical contamination.

The powered base is also compatible with the SWITCH TANK 4-gallon sprayer (49-16-28PS) and 4-gallon water supply (49-16-28WS) tank assemblies.

Includes M18 SWITCH TANK powered base (2820-20), SWITCH TANK concrete sprayer tank assembly (49-16-28CS), M18 REDLITHIUM XC Extended Capacity Battery Pack (48-11-1828), M18 & M12 Multi-Voltage Charger (48-59-1812), stainless steel wand, adjustable nozzle, fan nozzle and angled nozzle adapter.
