Has anyone out there put an attic fan into a penthouse top? I'd like to hear about any experiences out there. Thanks.

I've thought about doing it for a long time. And I keep coming back with the same answer:

- With all the penthouse windows open I have enough ventilation.

- If it is for use with the top down, I have a Fantastic Fan that fits one of my rear side windows.

I have one in my EB cab roof. LenS put one in the PH, search with him as author.

Yes, I had SMB West install one during the build. John Kalbach (since departed) had it done for me. This was a small fan that didn't void the penthouse warrenty. It works with the penthouse down (which is what I wanted). It has a built in fan. I bought it so that I could crack the windows, turn the fan on and keep heat from building up in the van (to protect my dog(s)). I am very happy with it.

I've attached a photo, the vent is the round thing on the other side of the solar panel.

dmeade0, that looks like it would fit on the RB cab roof the way my fan fits on the EB... that is if someone would rather punch a hole in the cab then the PH (personally I'm glad the PO did it for me...)

Living in the woodsy north east an attic fan is a great supplement for the penthouse top and a REAL must if you did not have the penthouse. Many times there is very little or no breeze in the woods and the air can be still, humid and hot. I don't think Vermont and Michigan would be much different. An open coastal area or higher elevations might be a different story.

We installed a Fantastic Vent 6600R/417 after we had the SMB install the penthouse top on our van. The 6600 model has 14 speeds, VERY quite on low speeds, and consumes about 1/3 the power of the 4000R model (but the 4000 is significantly cheaper). We do get lots of use out of it and appreciate the low noise when it is needed when sleeping.

You will have to plan the installation carefully because there is really very little structure in the light weight penthouse top.

Of course installing any fan one of the important questions to find the answer too is how much air does it really exchange? The 12 volt Fantastic Vent moves 920 CFM on high speed (at 1.9 amps)! That is about 2 air changes per minute for a van w a penthouse top.

I have a RB. The nice thing about letting SMB do the work is that it didn't void my PH lifetime warrenty.

The vent David posted that SMB installed for him is I think the VentLine VP-543 PW. It is a 6.5" diameter 100 CFM, 2.8 amp, 12 volt unit. This is based on comparing pictures of the two.
