Milwaukee Tool M18 SWITCH TANK System
January 18, 2019
Milwaukee Tool is introducing the industry’s first interchangeable tank solution with the M18 SWITCH TANK Interchangeable Sprayer and Water Supply System. Core to the new system is the M18 SWITCH TANK Powered Base, which provides power to three different interchangeable tanks: a 4-gallon water supply, a 4-gallon concrete sprayer, and a 4-gallon pesticide sprayer. The M18 SWITCH TANK System delivers instant, constant, and adjustable pressure with no manual pumping, and users can easily add on or replace any of the compatible tanks.
