Solar Ventilator Domestic Marine Caravan Solar Powered Vent

High quality steel outer casing - much better than the plastic one it replaced. Very easy to fit and runs silently and fast even on the most overcast of days. Fitted to polycarbonate roofing panel of conservatory which is about 1cm thick so the inner plastic fitting ring did not grip but I secured it with silicone sealant. Fixed main fan to roof with two beads of clear silicone and it is totally water-tight.

Does work but it's ok for a shed but not motorhome or boats not worth £40

prompt service. Item works as advertised so far

It is a little smaller than I was expecting thereby limiting the volume of air it will extract from my greenhouse. I have not placed it in situ at the time of writing. It works, that much I can say, but how efficiently, only time will tell.
