Pressure Hatch

Ooppss....wildmax!

Hi Darian,

I've been thinking about a scoop for sometime, any chance of a photo(s) of what you did?

Cheers

Our van came with the scupper. On a later visit to the factory, I had them fit the scoop, just to improve air capture. As for the comments here about well built vans not needing any dust control measures - I only know mine, and while I consider it well built, the off-the-shelf Camec window and door seals are certainly not airtight.

Re the scoop above, mounted at the leading edge of the roof; you can see the opened scupper, inside the scoop grille - note that when the scupper flap is closed (down), it reveals a hole in the rear of the scoop, allowing air to pass through (reducing drag).

Inside view of the scupper above, flap opened. The scupper vents come in two parts as I see it - one would need to cut a square hole in the van roof and slide the two parts in - one from above - one from below. Waterproof, UV stable, high strength adhesives are used outside - just screws inside it would appear. Whatever..... I can't see brands names on my fittings, but if you search the web for Camec and/or Fiamma vents etc. you'll see various offerings. Best of luck with it.

Darian, Thanks for the pics and explanation.

We don't need to cover our fridge vents (compressor fridge in use - it has hot weather hatches that seal when closed). I don't know what folks do with the fixed open fridge vents - sealing them up would compromise the fridge while mobile, I presume. The general idea though is that all openings need to be covered to get that bit of internal pressure. Maybe have a look on caravanersforum.com (technical) as well.

The fridge vents top and bottom on our van are open to the outside but the fridge outer cabinet is sealed to the inside of the van so any dust only enters in that compartment.
With a pressure vent, even though high mounted, I would have though that dust from passing vehicles could be a problem unless a filter of some sort was used. Yes/No???

Yes indeed Pop - dust can get in through the scoop/scupper - if we can't practically avoid the odd minor dust cloud from oncoming vehicles, we have to live with that - but it can be minimised as an issue by slowing right down. If we see a road train coming and the dust is our side, we try and do a brief stop.
