Max-Air Vent Cover

cousin_eddie · 03-01-2015, 11:27 PM

Our old pup had a Max-Air vent cover on the roof mounted exhaust vent. I liked it a lot, and would like to add one to our current unit, a 2014 Rockwood Premier 2514G. My concern is that on our old unit, the roof was pretty flat where the vent went through the roof. On the Rockwood, the vent is on the right-rear of the unit, and the roof is sloping toward the back at a pretty good pitch where the vent goes through the roof. Has anyone else added a Max-Air to one of these units? If so, how did it work with the sloping roof?

Don't have a cover on mine yet having one installed by camping world this spring. I'm going with the

It should be a non issue. They mount to your vent flange, not the roof itself.

I knew they mount to the vent, but my concern was air and water getting under the vent flange if it did not sit tight to the roof. Will rain splash in if there is a gap, ect.

Kinma - We were looking at that one as well. There was another similar unit made by Max-Air that the dealer carried, but the only one the dealer had was white, and would look out of place on my tan and black camper.

That might be a possibility under the right/wrong conditions. If it's a concern, I would probably use self adhesive foam weatherstrip and build up a graduated layer sufficient enough to be nicely compressed when the vent cover is closed/mounted.

I don't know if the ones you are looking at are hinged or not for cleaning.

As cheap as weatherstrip is, it certainly couldn't hurt. I would probably go with the thinner black strips and layer them rather than the thicker/lighter gray foam strips.

Cousin Eddie. If u watch the youtube video on the fan tasting ultra breeze it has the best flow of air and it looks like it mounts around the vent so that tells me that it shouldn't leak into the trailer unless your driving with the vent open. Or maybe very heavy sideways winds during a storm maybe but they are designed to unhook so you can clean them out. I don't think I'd worry about it leaking because it just mounts around the vent not to the roof well at lease the fan tasting does. The video seems to show how it mounts too.

If installed per instructions, no, etc.

No one can guarantee that you won't get wet in an extreme weather
event but you will be a lot dryer than without a vent cover!!
Get one!
I will never have a trailer that doesn't have the vents covered!

Even when installed correct the cover sits a 1/4 of an inch above the roof so there is a gap but water can't get in because the vent lid sits an inch above the roof. Even if rain was coming down so hard that it flowed like a river it couldn't get in any more than it would if you didn't have it. The regular ones that just go over the vents all the screws go into the metal lip the vent top sits on none go into the roof, the larger ones that cover the fans do have some screws that go into the roof, just make sure and seal them up good with lap seal caulk. I put my own on last spring and haven't had a leak yet. The biggest thing you need to remember when doing it is to respect the roof material, I put a piece of plywood on the roof to set the tools on to protect it if I dropped a tool by accident. I just looked at what your trailer looks like you have it easy you can lower roof to a workable height On my V lite I had to climb up on the roof also from the pics I looked at the slope of your roof shouldn't be a problem.
Hope this helps, it really is an easy job .

Anyone use the Max-Air cover for powered fans? I like the look of it better.

Forbes · 03-20-2015, 09:55 PM

We had two powered fans on our old unit 36RE and had three put on our new 36CKTS with Max-Air covers and really like them, had no trouble at all.

Maxxfan makes a cover specifically for power fan vents....can't remember the particular one. We have Maxxfan covers on ours, no issues.

itat · 03-20-2015, 10:27 PM

mark0224's picture shows MaxxAir's Fan/Mate model. MaxxAir makes a regular MaxxAir model, a MaxxAir II and the Fan/Mate that's made for high power vent fans. I installed a Fan/Mate on the Create-A-Breeze fan on my last trailer and never had any concerns about water coming in the vent. I had it open in rain all the time. I even left the vent cracked open slightly all winter.

f5moab · 03-21-2015, 08:36 AM

With either the Maxxair or the Fantastic fan covers, it appears the vents will not open 100 percent (about 3/4 from what I read on Amazon for Maxxair); is that correct?

Also, on Maxxair's site they show two different locations for Maxxaire II vent and vent fan covers but the covers look the same and I cannot find different part numbers. I'm wondering if they are the same!

f5moab · 03-21-2015, 03:07 PM

Another question....anyone try a Camco RV cover?
Trying to figure out why it is half the price of the Maxxair.

Amazon.com: Camco 40431 Roof Vent Cover (White): Automotive

itat · 03-21-2015, 03:33 PM

For a standard vent without a fan, the original MaxxAir or the Camco vent cover will work just fine. If you have a high power, high volume fan like the Fantasic Fan Create-a-Breeze then you should use either the MaxxAir Fan/Mate or the Fantastic Fan UltraBreeze covers. I don't think either the Fan/Mate or the UltraBreeze will allow the crank up cover on the fan to fully open. It wouldn't on mine with the Fan/Mate anyway.

f5moab · 03-21-2015, 03:44 PM

Can't remember, but the cover does not have to be all the way open on a fantastic fan for it to work...does it?

itat · 03-21-2015, 03:51 PM

No. It just has to be cracked open a couple of inches then the fan will start.

f5moab · 03-21-2015, 03:55 PM

Thanks, couldn't remember; been too long.
For the price, I might get two Camco models from Amazon and install on the fan and the vent. Heck two for 34 bucks, hard to go wrong.
