With regard to external covers over the vents, Fantastic has this to say in the FAQ's on their website:

"Q.
DO YOU RECOMMEND VENT COVERS?
A.
Vent covers restrict the airflow of your Fan-Tastic Vent by about sixty percent. In addition, covering your vent requires more frequent cleaning due to dust and dirt accumulation. Although we do not recommend any cover over your Fan-Tastic Vent, it will not void your warranty."

FYI...for those in the mood for spring breezes. Steve at Vintage Trailer Supply has worked with FanTastic to come up with a vent which blend well with the original look of the trailer.

They are flat domed and grey colored to match the existing vents. The colored base which sticks up out of the roof is usually white on fantastic fans. Somehow Steve got them to make a special batch of these in grey. They're going to look great!

The matching flat grey vent lid will blend in better with the existing lids, too. If you plan on replacing 2 out of the 3 vents for inflow/outflow purposes.

You can order +/-automatic opening rain sensor, +/-thermostat and curved/straight bezel.

The attached pic shows the flat lid and grey color (see the white in background for comparison--the flash washed it out a little).

I think I'm going to follow the "buttercup" installation instrucions!!!

say...that looks neat! but does it still allow sunlight through? or do you need to go w/ a standard lid to get that feature?

DPeakMD · 04-05-2007, 09:22 AM

The "flat opaque grey" will not allow sunlight in, but there is another option on Steve's website for a "flat translucent white" so that one probably would.

Kent, you can get all the needed parts from the Fantastic people, and upgrade the fan you have. Should take about 30 minutes or so to accomplish.

If you want to run your fantastic fan in the rain, put it on high, then switch to open. As soon as the fan starts to run, grab the knob on the cover opener and hold it so that it won't open any further. As soon as it quits trying to open, you can let go. This tip was given to me by the Fantastic Fan people a few years ago at International.

It is as easy as they say it is! The first one took about 90 minutes, the second one about 45. The easy way to remove old rivets is to use a steel putty knife and run it (hammer lightly) between the old vent flange and the skin.

Larry,

There is an article in the recent Vintage Advantage on how to use the old, flat cover on the fantastic fan for the vintage look on the outside. You might think about it.

Great post. Did you just ride up and ask to have the fan installed or did you make a appointment?
Thanks again for the info

I have a 25 Excella Classic, I just bought the 6000 Fan and after measuring it, it is too big to fit the hole....

I have not removed the old vent yet, so I do not know what it looks like inside... do I just cut the hole bigger and use lots of sealer?

As to the judicious use of adhesives and sealers I heartily agree!
Too much is as bad as not enough.
I like a little to squeeze out whan fully tightened/secured, just not enough to have to wipe off.

The neat trick is to use blue painter tape. Once all the cutting is done and the fan fits where you want it, run the tape all around the fan flange on the outside. I kept the tape about 1/8" away from the flange. You then use the sealant goo and replace the fan.

When I squished the fan down the extra came out onto the tape. A fast run around w/ a fingertip to make it pretty and carefully remove the tape.

Go drink beer. It is important to complete this task in the proper order.

Larry--

Out of curiousity... which sealant did you use? Dicor? Vulkem?

It was TremPro 636 which, as I understand it, is the new name for the old Vulkem stuff. It works very well.....................so far.

ronstory · 12-24-2008, 09:27 PM

Cool. I think Lewster mentioned on a long ago thread that Dicor was just the original stuff and I'm I'm sure the "new" Vulkem will work perfect as well.

Thanks for tip about using the blue tape to get a nice edge. My original vents have that silver stuff (Dicor) an it was applied rather liberally at the factory, I'm sure the professional term for it could be "slathered".

Man I'm sittin' here in a wind tunnel enjoyin' the breeze while it's mid 90's outside. I finished the installation of two Fantastic Fans today to replace my original noisemakers and I'm impressed with the performance and happy with my purchase. The fan over the gaucho is blowing in and the one in the bedroom blowing out, all the windows are closed, and there's a nice breeze blowin' through the length of Rancho Deluxe. The way that these puppies work I may be able to do without the ac at night this summer.

I need some inputs quick! I am about to install two Fantastic-Vent fans on my Globetrotter and I'm torn between which sealant to use. At first I was going to go with the Trempro 635, but then I saw Vintage Trailer Supply recommends 644 (silicone based adhesive sealant) to seat/adhere fans to the roofs of aluminum trailers. Thoughts???

I like the 636. You can also use the faster cure Vulkem, but I've found it to be a little "runnier" than the regular stuff.

Use any silicone-based sealant AT YOUR PERIL!!!!!!! You have been warned.
