Frequently Asked Questions

Does the unit come with a battery?

Does the unit come with its own charger?

Can the pistol grip be used with the wand?
Yes, we provide adapters that enable this usage

Why did you choose to use an SLA (sealed lead acid) battery instead of a Lithium?
We have found that the SLA battery is just as reliable as a lithium battery. The major reason for the decision is that the SLA battery is significantly cheaper and easy to find replacements for.

How long does the battery last on a full charge?
The battery should last 4-5 hours on a full charge.

What is the spray distance?
When using the right nozzles our backpack can spray up to 25ft.

Will what I want to spray work with your backpack?
Our backpack is extremely durable. We have customers who use our backpack for spraying a wide variety of solutions. From paint to concrete sealant to 50% bleach solutions our unit can handle almost anything.

Can I use nozzles from other companies with your backpack?
We are currently working on a system for adapting different nozzles with our backpack. Currently we have one working adapter that allows T-jet nozzles to be used with our backpacks. Please contact Hunter for more information (707-331-2848)

How do I clean your unit when swapping chemicals?
