Hi all,
Does anyone here have any personal experience of those rotating roof vents you often see on dog patrol and other 'service' cars and vans please?
I was wondering if one might help remove any fumes (fuel / wood treatments etc) from the back of a van, mainly when parked up?
The van in question has a full steel bulkhead and the fumes tend to clear pretty quickly as soon as the cabin blower is fired up (it's always on speed 1 at least) and I imagine these roof vents don't work (as well?) if there is no breeze etc.
So, are they quiet (given this is a van ), do they work worth the effort installing one and how long do they (bearings etc) typically last?
Is there a good brand that is the one those in the know fit?
Cheers, T i m
