Details and features

Chapin 63900 4 Gallon Self-Cleaning Backpack Sprayer

The Chapin 63900 4-gallon self-cleaning backpack sprayer is built for professional lawn & landscaping applications, and an excellent tool for homeowners. This backpack sprayer features JetClean™, a self-cleaning pump system, so the filter stays free of debris and virtually eliminates clogs. The pump directs a powerful bust of liquid through the tank filter on every downward pump stroke.

Its 4-gallon polyethylene tank is translucent and rust-resistant so it’s easy to view the liquid level while working and the extra-wide tank opening is wide enough to fill and quickly clean. Like other Chapin backpack sprayers, it comes with a 3-stage filtration system: one filter inside the tank, one filter basket under the tank cap, and one at the shut-off. All are removable so they can be cleaned. The seals are compatible with standard pesticides, fertilizers, and weed killers. It’s made in the USA with global materials and backed by Chapin’s 5-year limited warranty.
