You will need the following items to make this happen.
Maxx Air Fan –

This time went with a Maxx Air fan on this van conversion because well let’s face it…. It’s the best option although it is expensive the other models don’t compare. Trust us we have used all of them. The Fantastic Fan is trash don’t waste your time or money with that junk unit. It’s also very important to apply a lot of self-leveling lap sealant around the fan to make sure it’s watertight. It’s also very important to use butyl tape as well. We have done this process many times and this is the best way to do it.

If you follow along with this video you should have zero problems with this installation.

Finding Mark In Maine says:

I am not mechanical at all, however I have to say once installed my first Max air fan it went pretty well with surprise me. So it made the second one go even faster. The only thing I had to do on my second one was to create an inner frame for it to anchor to because the bus ceiling did not have the proper support to anchor too.

J. G. says:

As always nice work and explanations.
I put an oak frame under the fan so the screws would have more clamping force. I'm not a trusting person, and my van has a fiberglass roof.

There’s actually a better way to do it without needing any maintenance ever, butyl and lap sealant isn’t a long term solution and eventually people generally end up needing to maintain it or replace later.

Best way is to use something like SikaFlex 221 as the sealant (which is what automotive windscreen repairers and manufacturers use to seal windscreens or bonded windows to vehicles and of course that’s only done once, ever. You’d use it I conjunction with the Sika Primer and the Sika Aktivator.

So basically.
– cut hole out, remove shrapnel, paint bare surfaces to protect against rust. Allow to dry.
– clean around surface with methylated spirit, allow to evaporate.
– use sika primer, preps surface ready for sealant, drys fast.
– use sika aktivator paint it around the surface where the sealant will go (so replaces butyl in this video), allow to dry, drys really fast
– apply a triangle shaped bead of sikaflex 221, roughly one tube per maxxair fan, or two tubes for a large domestic skylight. You can make the triangle shaped bead with the nozzle that comes with the sika flex as it has notches in the correct shape.

Voila. It’s staying in forever with zero leaks ever.

A similar solution will be available if you don’t have that there, just look up what people use there for replacing vehicle windscreens, it’s normally some sort of iso alcohol to clean the surface, a primer, sometimes and activator (not always) and then a pro sealant specifically for window bonding that’s compatible with plastics. I see too many people using butyl and lap Zealand in the van and mostly motorbike flipping and bus converting community and it’s not the best solution.

Hope that helps. Plus it’s a far, far neater job.
