Maxx Air Fan for 21'

[clarity6406]

Hey Everyone,

I have a 21' 1994 Sovereign with two pop up vents, but no fans. I am thinking of purchasing and installing Maxxair 12V Roof Top Fan/Vent. My question is, should I install 1 or 2? I have two vents, but the trailer isn't that big. Would one pull out enough of the heat? Also, I'd have to run power to them. If anyone has done this before, is it a big job?

Also, does anyone have their best recommendation for fans? I'm not 100% sold on my choice.

Thanks!

I installed 3 in my 32' Avion. One in the bathroom is exhaust only. The other two have remote controls and can be open in the rain. They fold down when not in use. It wasn't difficult to install them, but I had 12v already run to them. The biggest deal was cutting the holes square (Avions have rounded corners on the vents). They really suck the air out, though, so I'm pretty sure one would be enough for your trailer. They can be reversed to blow air in as well. I really, really like them. I have a fantastic fan in my 17' Bambi II, but I like the MaxxAir with remotes better. They have a thermostat on them too. I actually used the remote when I got a little chilly in bed. Love it!

Thanks! That's great info. I had 2 fantastic fans in my first 25 and wasn't a huge fan. Have read really great things about the MaxxAir.

Do they have rain sensors? I currently have two MaxxAir covers (from previous owner) but am thinking of taking them off. Just curious if they have the same feature of auto turn off like the Fantastic Fan

Never mind, I see that yours is the rain shield built in!

I have two of the Maxx Air fans on our 30' trailer. The fans work well pulling air in/out during rainy days or traveling along the highway. I also leave them open during the summer months when the trailer is not being used so it can breathe on hot days.
They seem pull about the same cfm's as the Fantastic Fan.
Definitely install at least one, two if the budget allows.
I did the install work myself. The toughest job is removing the old vent and caulking. Use some Sikaflex self leveling caulk and stainless steel screws when installing.

Shouldn't be a problem if you are handy. Might have to trim the holes to fit the fan . You should be able to get power from the overhead light beside the vent. I did two on my 25'. Better to have too much as not enough.

I installed one MaxxFan in leau of the old pop-up vent in the front of my '93 21ft. Sovereign. Just open the other manual vent above the bed or crack a window. The fan has plenty of power to handle the interior volume of the coach. The design allows you to operate the fan during rainy weather, a big plus compared to the Fantastic Fan. You will love it!

That's great! I didn't know I could pull power from the lights. That will work great. Thanks for the info

We have 2 Fantastic fans in our 27' Safari W/Slideout; we run one pulling in, the other out & it keeps the trailer cool. BUT they are noisy & the one in the bedroom, we do not run overnight. Also, we had to put the outside covers on as the rain did come in as well as the sensor kept opening & closing them when raining which was annoying noise wise. I wonder about replacing the bathroom small fan with a Maxair but not certain if they fit in the same size opening. That fan in the bathroom is rather useless & again noisy.

One of the first things I do in my Airstreams is change the Bfs to MaxxAir fans. They work great- even when it's raining. Using one pulling in and the other exhausting moves a lot of air. Just make sure you're not drawing in near a plumbing vent. It will become very obvious if you do!
