CHAPIN 61900 4-Gallon Commercial Backpack Sprayer - Translucent Tank, Stainless Steel Wand & 3-Stage Filtration

The CHAPIN 61900 is a Made-in-the-USA 4-gallon commercial backpack sprayer built for turf, tree and professional landscape applications with a stainless steel wand, three nozzles and three-stage filtration.

Compact, durable and designed for frequent use, this backpack sprayer combines a translucent polyethylene tank for easy level checks, chemical-resistant seals, and padded carrying support so you can treat lawns, trees and hard-to-reach areas with confidence. It pairs professional-grade build features — stainless extension wand, reinforced hose and multiple nozzle options — with user-friendly details like a large fill opening and an integrated filtration system to reduce clogging during routine applications.

How does the CHAPIN 61900 handle different spray patterns and materials?

The 61900 arrives with three interchangeable nozzles and an adjustable stainless steel wand that lets you choose stream, cone or fan spray patterns depending on the job. Brass and poly tips give you both durable metal performance and lightweight plastic options for varying spray behaviors and chemical compatibilities.

• Included nozzles: adjustable brass, poly-cone and poly fan tip for stream, cone and fan sprays.
• Adjustable stainless steel 20-inch wand for precision and reach.
• Dial and tip adjustments allow quick transitions between application types.

What protects the pump and nozzles from clogging?

The sprayer uses a three-stage filtration system to catch debris at multiple points, reducing the chance of clogs that interrupt work. Filters are placed at the tank opening, near the pump and in the shut-off to trap particles before they enter the hose, wand or tips.

• Basket filter in the 5-inch cap catches larger debris while filling.
• Internal filter near the pump captures smaller particulates before pressurization.
• Shut-off filter provides a final screen to protect nozzles and maintain consistent flow.

Is the CHAPIN 61900 comfortable and durable for extended use?

Designed for professional and commercial work, the sprayer balances rugged components with ergonomic supports to ease long sessions. Padded shoulder straps and lumbar support reduce strain, while the translucent poly tank and durable seals make the unit low-maintenance and chemical-compatible.

• Padded straps and lumbar support help carry a filled 4-gallon load comfortably.
• Translucent polyethylene tank shows solution level at a glance and resists common lawn chemicals.
• Chemical-resistant elastomer seals and gaskets extend component life with fertilizers and pest-control products.

What warranty, support and origin information should I know?

The 61900 is manufactured in the USA from global components and backed by Chapin’s 5-year limited warranty and US-based technical support. Chapin provides phone and online resources for troubleshooting, parts and replacement guidance to keep the sprayer in service.
