Roof vent. Fiamma, flettner?

[Frosty3006]

Guys im trying to work out what the most cost effective way of adding ventilation to my mk6 swb is. I keep seeing people talking about big fiamma vents, having a couple of flettners, motor powered, window deflectors so the windows can be used.

Im thinking ill probably just fit one vent and buy some window deflectors to allow ventilation in the front to circulate. But whats the best vent for the money? My conversion is all about budget (arnt they all!) and also if a small flettner will be just as good as a large sqaure fiamma ill go down that route.

Advice please!

I'm a fan of the 5-way MPK rooflights, they don't look as swish but they are cheaper and they do work very well.

Thanks mate Ill check them out.

See a lot of cheaper rotary style vents on ebay. I imagen I would probably need two at opposite ends of the roof to allow for good air flow through the van. These worth considering?

A fletner is 70 shellkels an electric ventfan is 150 shellkels
And ...
A vent fan is equivalent to five fletners air volume moveing wise

Might be more that that actually

Not 5 fletners ten
1 ventfan =10 fletners

Guys, one thing ive just realised is I need to be able to still drive through car park with height restriction bars! I think my SWB just clears.... this scuppers my plans somewhat as I was leaning towards a large style MPK or Fiamma vent.

Suggestions?
