DeWalt recently premiered their 20V MAX 4G Backpack Sprayer (DXSP190681) that holds 4 gallons of liquid for a variety of spraying applications. With 10 adjustable spray settings, this new backpack sprayer makes it easy to evenly spray larger areas without having to carry around a heavy tank.

Adjustable Nozzle

The 4-gallon backpack sprayer has Variflo technology, which allows you to adjust the flow for multiple different applications. There are 10 settings that change the way liquid sprays for consistent and repeatable spraying. Whether it’s for weeding and feeding, disinfecting, finishing concrete, or controlling pests, this sprayer will get you ready for the job.

Filtration System

The DeWalt Backpack Sprayer has a triple filtration system to reduce clogging in the hose from debris and buildup. This sprayer works best with water-based formulas for the most effective spraying, but can be used in other settings as well. The following chemicals can also be used:

  • Densifiers
  • Penetrating siloxanes for concrete finishing
  • Cure and seals
  • Water-based dye and stains

The comfort grip handle and shut-off switch on the sprayer is easily operated even with heavy-duty work gloves, so you can be sure that your hands can stay protected from chemicals. This powerful sprayer can spray up to 34 feet horizontally and 35 feet vertically to cover a wide surface area with ease.

Backpack Design

This backpack style sprayer has a secure harness that locks around your body to evenly distribute the weight for added comfort. The 50″ hose is kink-resistant to prevent blockages while in use so that you can get an even stream every time. The heavy-duty 21″ stainless steel wand is super durable and 4x stronger than poly material. This sprayer comes with a 20V 6.0Ah battery and charger. While in use, the battery fits into a sealed and water-resistant compartment to keep it protected from the elements.
