Roof fans / vents, suggestions and experiences?

[Endorphinix]

Hi, I am converting a Hightop LWB custom into a day van. I'd like an electrical extraction fan for the summer to help keep it cooler for the dogs etc. But I can't decide between installing a simple fan or to get a fiamma roof vent, the 28x28 one with integrated fan.

The only issue is it looks like it's permanently vented, so am concerned it will cool the van too much in winter.

Also I'd be grateful for any experience with either style of fan and if there is a noise issue when driving aswell.

Thanks, Keith

I've got the Fiamma Turbovent 28 (the "crystal" see through version) on my camper, and overall I really like it.

For:

Easy to fit - you just need to cut a 28cm square hole in the roof.

Built in switch with reverse operation - blows air out or sucks air in.

Let's light into the van.

Opens wide for maximum venting.

Permanent venting so you can still get some venting effect even when it's closed and pissing down. I don't find it let's the cold in like you worry it might.

Built in mosi net to keep the bugs out.

Not noticing any wind noise when driving.

Spares parts are available if you need them.


Against:

Sit's quite high off the roof.

Fan is NOISY!

Fan is not variable speed - it's hurricane force or nothing. I'm going to fit a pulse width modulator to it, so I can turn the speed (and noise) down when I want.

Seems to let a lot of external noise into the van, even when closed.


It's worth pointing out that every other fan/vent that I looked at, were all permanently vented too.


I considered these but went with the Fiamma. I saw a couple fitted on vans at Transitmania - they looked really good.

I've got one of those vents off egay on mine ^^
Probably a tad loud for you camper ladies though
But good for sucking farts out

As usual BJT, you've spotted a crucial plus point that I never even thought of.

He he, that's a necessary requirement! Bigjohnthomas, yes I'd been looking at those as well, is it loud, driving or in operation?

No noise driving its just a wurring whooosh motorish noise
Like air makes when you push it round
Its a nice big hole so you get some vent without switching it on
Its very neat though and prob about the same price as a fletner and their sh*t
Have one of those in my other van slightest bit of wind and rattle rattle rattle
I'll find a pic ....

I need to have a look at the roof again as its an L2H2 and the roof is heavily ribbed.

Has anyone made a diy installation with a computer fan and if so what did they use on the outside of the vehicle?
