Get filtered water from one portable setup. This AR3 bundle includes three-stage filtration, a pressure regulator, splitter, hoses, and storage case for campground hookups.
Anyone who has hooked up to the water at a campground knows what can come out of those lines: sediment, chlorine, and fine particles that slip through standard RV filters. The AR3 filters that water in three stages:
This gives you water you can trust for drinking and cooking straight from your RV faucet.
Water pressure isn't the same at every campground. Some spigots deliver more pressure than your RV's plumbing was designed to handle. The included stainless steel pressure regulator connects using standard 3/4" garden hose threads and controls incoming pressure before it reaches your RV. The regulator is factory preset to 45 psi and adjusts from 0 to 160 psi. It includes a dual-layer inlet screen that helps keep sediment out of your plumbing while maintaining a flow rate of 2 to 4 gallons per minute.
One campground spigot often has to do more than one job. The included stainless steel splitter connects using standard 3/4" garden hose threads and gives you three independently controlled outlets, so you can run your filtration system while still having connections available for another hose, filling a bucket, or other campsite tasks. Each outlet rotates 270° to make hose connections easier in tight spaces.
The system includes one 25' stainless steel hose and one 5' stainless steel hose with standard 3/4" garden hose connections for flexible campsite hookups. The stainless steel braid resists kinks and abrasion while helping the hoses route through storage compartments and wet bays without restricting water flow.
When the campground spigot is your only water source, the system sets up between the faucet and your RV. Instead of a fixed installation under the sink, the system connects between any standard pressurized campground water source and your RV. The outlet hose connects directly to your RV's standard city water inlet, just like any other campground hookup. When you're done, the complete system packs into the storage case until the next stop.
Ratings & Reviews
So far it seems good. Always appreciate the quick service of trailer. I am enjoying better water in my RV. Thank you.
Great product for our RV. Really like the quick disconnects.
One thing that this would make this purchase complete would be Blu Technology 90-Degree Quick Connect Hose Adapter - Stainless Steel. But I would like to thank etrailer for coming through with quick and great service and all the information that I would need.Thank you again.
It’s a great system. We were told that our 2027 Grand Design Influence would include this but it did not.
Important to us to have clean water. Thanks for a great product we can be confident in! Seems to be something that is rare right now.
GoBlueTech AR3 is small and compact. Great for Van Life! I love eTrailer! The shipping was fast and the product was available. Thank you eTrailer!

I too enjoy good filtered water Eileen! In fact, I don't really trust those who say there is no difference =) What kind of RV did this go on? Have you been on any fun trips this year?
