Last week I replaced my July 2023 Dolphin S Embassy Vent Fans with their (Vent Fan UPGRADE KIT) Thank you Nolan ! - the new FANS are STANDARD ON ALL NEW DELIVERIES - they are TWICE the Air Flow & quieter - very happy with the result ! :-)
the kit included easy to use connectors on the new fan wires - the front driver & passenger vent fans were very easy (30 min ea) due to their location & height - just disconnect any speaker wires & porchlight connectors - the back vent vans have a single cover that is higher up & extends across the entire back - another pair of hands(helper) makes this much easier - once you've done one vent fan you learn to do the others no sweat (same process)
As I understand it, the scuppers are wired so opposite ones pull/push air so it's not surprising that no air would be coming through the window/screen as the air exchange is already perfectly balanced. By putting in a roof vent/fan you now have annual maintenance to avoid leaks as well as the possibility now of roof leaks.
@@amorevan I wonder if the scuppers have a damper on them if they're not on...maybe the ones that were off were still letting air in even though they weren't on? Perhaps having all 4 scupper fans as exhaust and vent openings lower in the van or just opening the windows and doors would do a better job at exhausting the hot air. I believe each fan moves 130cfm so all 4 would be 520cfm which would completely exchange the air in the van roughly every 75-90 seconds.
We are still debating on that. Since we live in a very hot and humid climate, I don't see much point in a ceiling fan, but as we travel to more moderate temperatures, it would be good to have a fan in the back for air flow. We have a small battery powered fan we use on warmer days, and that has worked so far, but the more travel we do, the more we need to adapt to various weather conditions. Who added the fan to your van? You didn't do it, did you?!?
Robert, we had it done at Embassy. If I tried to cut a hole like that in the roof myself, they’d be fitting me with a new leg! Air movement is one thing, but exhaust is another. We found our van was warmer than it should be at night when temperatures outside dropped, because the hot/warm air that accumulated during the warmer/hotter day had no place to go. Hot air, of course, rises, and once trapped above the “scuppers,” we found it hard to expel. The roof fan solves that problem.
@@amorevanI had two installed in my previous 37’ Holiday Rambler where I had one pulling and the other pushing. Those fans are quite easy on the ears and move a Lot of air. I also used them both pulling or pushing. Massive air movers. I am considering one for the Embassy. Will you be at their event next week?
Would sometime love to see before and after pics of your van showing roof fan. Your videos are very informative thx!

Sounds good 👍
Ron - So glad to hear. Waiting on Embassy to make an announcement. Did you install or Embassy? If you did was it difficult?
Are the New Vent Fans directing replacing the original factory installation or are the mounted through the roof, like the Max Air?

I have the old style and not much air comes out even when turned to high. Can you feel the air coming out now?

In the experiment shown in the video, only the out-blowing scuppers were on.

How did you change that all the scupper fans to blow out? Original installation was 2 blow in and 2 blow out?
Only 2 blow out. In the test in the video, I had only those 2 on.
Any comments on the noise differences between the two systems?
At the speeds necessary to get good airflow, the MaxxAir is considerably quieter (and at a more pleasant pitch)

Hi, Gene. Yes, we’ll be there.
