I just installed the RV airflow System on my 2018 Imagine 2250RK and I can feel a lot more air coming out of the ducts.
 
My 337rls came with one factory installed on the main unit. I liked it so much I now have one installed on the bedroom unit.

I installed one a couple of days ago. I have a handheld anemometer, so I did some measurements with only the front vent (in the bedroom) and the back vent (over the kitchen) open.

Before install I got a maximum of 8.5 f/s out of the front vent and 8.8 f/s out of the back. Post install, I was seeing 12.7 f/s and 13.6 f/s respectively. There was apparently a lot more short circuiting than I thought.

I was messing about in the trailer yesterday, I could only get the temp down to 82 inside. But it was 102 outside and the trailer is in full sun, so I was pleased. Normally I'm in the shade
 
my 2250RK has the Furrion AC unit in it and they don't make the RV Airflow insert for this unit (yet). So I did what I could ot seal up the outlet of the unit and it did increase the airflow quite a bit but suspect it could be better if it had an insert such as the RV Airflow plenum. So far the AC works great and have only had it out in temps in low 90's and it was able to keep its in the low 70's were we set it....

I put one in my 2019 297RSTS (1 A/C unit) and am extremely pleased. I was planning on putting in a 2nd A/C but not now. I saved a ton $$$. I did not take measurements before/after but can feel the difference. We have not hit extreme heat yet, but i know it will perform better than the last 2 summers...
 
We added tha RV Airflow kit to our Imagine 2400BH and we’re VERY pleased. We were in the heat and humidity of Arkansas earlier this summer (and it was hot AND humid!) and never had to bump the A/C over “Lo Cool” where last year we never had it lower than “Hi Cool.”

Big difference in air flow with the added benefit of being quieter - which shouldn’t be possible. I’m glad we purchased directly from them rather than making our own version. Happy to support a small business that spent a lot of R&D money to create an effective and needed product. Kudos to them!

By the way, we also used the Changing Lanes discount code to save a couple of bucks and support Grand Design YouTubers.

After watching all of the videos bout this product (almost all of them were with Coleman or other units) we purchased one of these for our 2016 Dometic unit w/Heat pump. When we installed it we found that our model number AC was not 'exactly' the same as the newer ones. Fair enough. The difference was that the internal baffle between the intake and outlet needed to be repositioned about 3/4 inch. I removed the baffle assembly and drilled out the tiny spot welds that held the divider, and then pop-riveted it back in the correct position. A little foil tape and Viola!

The difference in the air flow cannot be determined without testing equipment, but I can say that the difference in volume is astounding. We can actually sleep with the AC on now. Before it was way too loud!

The insert for our non-heat pump Dometic AC is just now available this week. We'll be ordering one for our other unit will be placed shortly, knowing that I will have to do the same modification. This is good!
 
One rv airflow came in the living room unit, and I purchased a 2nd one for the bedroom. Once you get past the cost for a chunk of Styrofoam, it really works! Both air conditioners operate in unison now, and both thermostats read similar Temps. RV is much cooler in the heat of the day, and units actually cycle on & off now.

Installed the RV Airflow system in my 2018 303RLS Reflection, the improvement in air circulation throughout the coach was simply amazing. I highly recommend them..

Been camping in Maine this week temperatures were in mid 90’s, the coach was 72, couldn’t ask for more

Hello James9793;
Just wondering what is your unit? Curious if my 2020 Reflection 29RS may have the RV Air Flow installed already.
 
I have a 2021 315rlts with Coleman Mach 15 ac units.

Quick way to tell is by opening the duct bypass vents at the unit. If no air comes out, rv airflow may already be installed in the plenum.

I just installed the RV Airflow systems yesterday in both AC's in my 303RLS. These really do make a big difference in the amount of air coming out of the ducts. I also sealed up gaps in the ducts with foil tape where they terminated into the plenum. Lots of gaps with one being almost a half an inch where air was escaping into the attic. For those complaining about the costs I don't think they understand what it takes to bring a product to market and with a somewhat limited market these costs have to be spread among fewer units. I tend to look at something like this in terms of it's value over time and not just the initial cost.
 
I installed one on my 375 RES in the bedroom unit. No equipment to verify flow increase, but improves flow enough to feel right off. I have the Coleman unit. Simple install and was amazed at the soddy orginal install from the factory. Well worth the investment.
 
Having trouble getting airflow to front bedroom vents from ac on my 310 GK. Says racetrack ventilation but bedroom ac does not appear to be tied into plenum. At dealer and looking. Anyone have similar issue? Will vent flow devices improve airflow if connected? Real pain since I have heat pump option and little to no airflow from living room ac… no heat without running the furnace.

The other good thing about RV AirFlow is the team behind it. I bought their first gen product in March 2020 and later in the year they were all over social media asking owners to contact them - they wanted to replace our units with the current version at no cost. They just needed shipping information.

Best regards,
Chris

We have a 2019 29rs and after reading all the positive posts about the RV Air flow, I took my cover off and found that we have it already in the unit. Had temps this week of 112 in Wash state and rv was in the mid 70's.
