Factory Roof Vent H72

[Ciki62]

Hi,

do you have any experience with factory roof vent ?
. is it quiet
. is it operated from AUX battery also when engine is switched off
. ...

I am not sure if this will be nice for ventilation. i don't need roof windows, ventilation is enough.
My conversion will be very simple.

Hi there,
asking your sales agent/dealer? He should have all the technical details, regarding air flow, noise level etc..
