Chapin ProSeries Professional Backpack Sprayer 4gal Capacity

Chapin ProSeries Professional Backpack Sprayer 4gal - High-Capacity Coverage Without the Fatigue

The Chapin ProSeries Professional Backpack Sprayer is built for operators who cover large areas and need the tank capacity and physical ergonomics to do it comfortably. The 4-gallon chemical-resistant poly tank carries enough volume for extended application runs, while the positional pump handle accommodates both left- and right-handed operation without awkward repositioning. Chapin's 3-stage filtration system keeps the spray line clean, and chemical-resistant seals ensure reliable performance with harsher weed control agents, pesticides, and fertilizers. Multiple nozzles are included for flexible application patterns. Made in the USA with global materials.

Key Features & Benefits

• Positional pump handle: The ergonomic pump handle can be used on either side, accommodating left- and right-handed operators without adjustment for comfortable, fatigue-free operation.
• Chemical-resistant seals: Seals are rated for use with harsher formulations including concentrated weed killers, pesticides, and fertilizers without premature degradation.
• 3-stage filtration system: Chapin's multi-stage filter removes particulate debris at three points in the flow path, delivering consistently clean spray output and protecting nozzle performance.
• 4-gallon translucent poly tank: High-capacity rust-resistant tank reduces refill frequency during large-area applications, with see-through walls for easy level monitoring while wearing the unit.
• Multiple nozzles included: Adapt to different application patterns - fan spray, cone spray, and stream - without purchasing separate accessories.

Who Should Use This

The Chapin ProSeries backpack sprayer is the right tool for cultivators and operations that manage large growing areas and need to apply pest control, fertilizers, or weed management products over extended runs. The backpack carry system distributes the loaded tank weight evenly across the back and shoulders, making it significantly more comfortable than a hand-carry pump sprayer for high-volume applications.

Compatibility

Compatible with herbicides, pesticides, and fertilizers. Chemical-resistant seals extend compatibility to more aggressive formulations compared to standard pump sprayers. Made in the USA with global materials. Rinse all components thoroughly after use with harsh chemicals to protect seals and prolong service life.

Frequently Asked Questions

What does "positional pump handle" mean?

The positional pump handle can be placed on either side of the backpack unit, allowing both left- and right-handed users to pump with their dominant hand without any tool-based adjustment.

How does the 3-stage filtration work?

Chapin's 3-stage system filters the chemical solution at multiple points as it moves from tank to nozzle, removing progressively finer particulate at each stage. This protects the nozzle from clogging even with less-filtered input solutions.

How do I put on and adjust the backpack unit?

The backpack harness is adjustable for different torso sizes. Don the unit like a standard backpack, tighten the shoulder straps for a snug fit, and adjust until the tank sits comfortably in the center of your back without swaying during movement.

What nozzles are included?

The ProSeries backpack sprayer comes with multiple nozzle types for fan, cone, and stream spray patterns. Refer to the product documentation for specific nozzle configurations included with this unit.
