Milwaukee 3019-20ps M18 4-gallon Backpack Sprayer

Product Description

The MILWAUKEE 3019-20ps is a battery-powered 4-gallon backpack sprayer built for professional landscape maintenance and similar trade applications. It delivers constant, adjustable pressure up to 140 PSI without manual pumping, and reaches a vertical spray distance of 24 feet. A 5-mode flow rate knob adjusts output from 0.1 to 0.52 GPM, covering a wide range of spraying tasks. The unit is part of the M18 platform and operates on an M18 battery (sold separately). This is a tool-only listing and does not include a battery or charger.

This sprayer is intended for professional landscape maintenance, pest control, and similar applications where consistent, hands-free pressure control is required. The SWITCH TANK design separates the powered base from the tank assembly, allowing operators to swap tank assemblies between applications without cross-chemical contamination. The powered base is also compatible with the 4-Gallon Water Supply Tank Assembly (49-16-19WS). With the M18 REDLITHIUM XC3.0 battery (sold separately), the unit delivers up to 20 tanks of spraying per charge on Mode 3.
