Dewalt 190742 Backpack Sprayer 4 Gallon Battery Powered

Product Description

The DEWALT 190742 is a lithium-ion powered 4-gallon backpack sprayer built for professional-grade spray applications without manual pump cycles. The battery-driven motor maintains consistent output pressure up to 90 psi, delivering a steady flow through a brass adjustable nozzle capable of stream, cone, and foam patterns. The polyethylene tank is rated chemical safe for a wide range of solutions, and Viton seals and gaskets provide compatibility with aggressive chemicals. A reinforced 50-inch hose and a 21-inch polypropylene and stainless steel wand give the operator reach without repositioning. This unit is installed and operated by landscape technicians, pest control professionals, and facility maintenance crews.

This backpack sprayer is designed for field and facility applications including the application of cleaning agents, sanitizing solutions, fertilizers, herbicides, fungicides, insecticides, and water-based penetrating concrete sealers. The no-pump lithium-ion power system makes it suited for extended spray runs on large surface areas, commercial grounds maintenance, and job sites where operator fatigue is a concern. An in-tank filter helps protect the nozzle and pump from debris. The adjustable nozzle allows switching between spray patterns on the fly to match the application surface and product requirements.

Installation Notes

This unit is operated by trained applicators familiar with the chemical products being dispensed.

Follow all label instructions for the chemical being sprayed, including required PPE. Inspect seals and hose connections before each use and replace any worn Viton components promptly to prevent chemical exposure.
