Maxair or Dometic fantastic vent

[Poutie57]

I’m after opinions on which people think is the best both shift similar amounts of air and both are remotely controlled. I have discounted the Fiamma simply because of the fact of no remote.The other question I have is has anybody fixed it to the roof without using screws as I don’t really fancy drilling loads of holes then possibly suffering the problem of water getting in because my van has VB full air so when it rains the water pools rather than drain off.
Any advice would be appreciated

We’ve owned both fans and much prefer the Maxxair as it’s much quieter and has a greater range of speeds. On its lower settings it is virtually silent, which is a benefit at night.
Apparently it can also be used when driving, though we’ve never tried this.

Thanks a lot do you know whether yours is screwed in or they just used mastic

The Maxair is screwed, not sure about Fiamma, Omnivent is clamped - which is why I chose it.

I replaced a Dometic Midi Heki with a Maxxair on our previous van and we were very pleased with it.

Fitting the Maxxair may take some planning.

If your roof is ribbed then you need some way to fill the gaps. Fortunately I could use the adaptor plate that came with the Dometic Midi Heki.

The Dometic Midi Heki used a collar under the van skin which the vent screwed down into which securely clamped the vent to the roof.

The Maxxair uses numerous screws around the rim which screw down into the van roof. The thin steel of the van roof may not be enough to take the screw.

I fitted a rim of wooden blocks under the steel roof skin and inside the roof liner and screwed down into the wooden blocks.

Sealed with Sikaflex.

If you buy or own an omnivent take a spare pcb with you. They have the common fault of switching themselves off, it gets worse and worse until they won't come on at all.
