Maxxfan Dome Installation - City Express/NV200 Van Build

Sharing my installation experience with this dome fan. Hope you can find this helpful!

This seems great. I bought a second van (I know) and now I have a mini-rig and a tall full size. Anyway, this seems great for my mini rig, just need some airflow at night for condensation, etc. and not to cool and battle the heat. I really was hoping I wouldn't have to install a 14x14" full size vent fan.

Hey there are paint bottles about the size of large nail polish bottles and it dries almost instantly. You put it on a cotton swab. Way faster and no masking necessary

Great video, thanks :) There's load of videos of people 'installing' these fans, except that they all fail to cover the actual installation, so this was super handy 👍. I'll be making my own video soon so I'll be sure to pop a link to yours :)

Excellent video! Thanks!

Nice install. I was wondering why I saw everyone using a jig saw instead of just a simple hole saw...glad it works. I saw some people using a 3D printed spacer for the roof ribs instead of layering butyl tape. I'm wondering how that holds up.

[@caseyvideodiary]

I think the main reason for this is that the instructions specifically call for a 6-1/4" hole, and the only hole saws I could find in that size were for wood only. The 6" worked fine but it only had about 1/8" clearance on the diameter. A friend of mine used a plastic spacer for his roof fan and it cracked pretty quickly so I didn't bother with that. I've been living in the van for about 6 months now and I have yet to encounter any issues with this fan install. Fingers crossed about that, though.

nice work.

New subscriber excellent information.

Hey bro! Any comments or reviews on this fan? I'm looking at buying it instead of the bigger square MaxxFan. My van is pretty small so I was thinking this should be good enough for airflow. Thoughts?

[@caseyvideodiary]

It certainly does its job. If your van is around the same size, I’d say go for it and install one of these. Keep in mind that it is exhaust-only and can’t be reversed like the traditional fan blades in a larger fan can. The airflow is definitely sufficient to regulate temperature and humidity, but don’t expect it to produce a crossbreeze.

How much CFM is it on full speed

[@caseyvideodiary]

Airxcel states 200 CFM in the spec sheet. I have no way of independently verifying that. It’s exhaust only so you won’t be getting a breeze from it either way.

[@mustangdbest220]

@@caseyvideodiary AHHH WOW 200 CFM NICE

[@zerobambiro]

I am thinking about buying the same for my nv200. Did you try it already and is it strong enough?

[@caseyvideodiary]

It’s definitely strong enough for the space, but if you’re expecting much of a noticeable breeze you’ll be disappointed. It mostly just does the job of regulating temperature/humidity. One of the great features of this van is all the ways you can open doors and windows for crossbreezes, so the only time I’m ever relying on just the fan and a cracked window for ventilation is when stealth camping. For that purpose I recommend pairing this with a pair of window rainguards.

Why the backing board?

[@caseyvideodiary]

Without a backing board there is nothing to resist the screws pulling out! Remember, this has to resist windshear highway speeds as well as backing out from the constant vibration of the vehicle. 1mm of sheet metal isn’t up to that task.

[@12vLife]

Do these move a good amount of air ? Was thinking of a custom solution with a powerful 9" USB fan.

[@caseyvideodiary]

It moves enough to equalize the temperature. You can’t really contrive much of a crossbreeze out of it. I wouldn’t use it alone in a space bigger than this. Also be aware that it is exhaust-only and the impeller-style blades don’t do anything when reversed.
