12V Fan

Can't tell you about this particular fan, but I can tell you I fitted my boat with a 12V computer case blower that draws 0.3 amps and moves over 30 CFM. See this link for example and note the price. http://www.newegg.com/Product/Product.asp?Item=N82E16811999039

It works most excellently as a windsheild defroster and also to move air throughout the cabin. A little loud but not objectionable. Am thinking about mounting one or two other fans (as opposed to blowers) made by the same co.
 
We use the West Marine "Battery-Powered Crew Fan". In fact we have two and use them only with the batteries. They last well beyond the 300 hrs when run on low and are easy to move around. And they are super quiet. Just never have purchased the 12v adapter.
 
We have the 747DC-WCS - the one with the blade with no cage
around it. They are expensive, but small. They work well. I'll
probably mount it under the cabin shelf in this boat. Or maybe just
leave it free standing. I made a little base for it out of a piece
of oak.

I guess they are too funky for thieves. It was stolen once, but
later found in a field where the thieves held a bonfire after their
pillaging.

I have used the Hella fans for many years. (West Marine now brands the single speed). They are fairly quiet and effecient. What is important is why you want to do with the fan. If you want to move large amounts of air, consider the WalMart large D battery fan (with 12 volt plug) or the Endless Breeze. I suspect that the Caframo fans will work as well as the Hella for defrosting or moving the hot air from the top of the cabin--but for ventillation, you want larger fans.
 
I needed something to keep the windows clear of fog. My wife picked up a de-fogger like this one from West Marine and it was essentially useless (kept an area of the window about 4" x 8" clear). I found a simple 6-8" diameter 12V oscillating fan at the local Shucks auto for about $12. I clip it on the electronics shelf and it keeps the window very clear. It's a cheap solution that can be moved around.
 
You have to be a bit long in the tooth and have lived in a cold climate to relate to this, but do some of you remember the plastic or glass panels that people would stick to the side windows of their cars. They would give an air space of about 1/8th of an inch and would give you a little panel to peer through while the rest of the window was fogged or frosted. Can't remember what they're called, but I've wondered if anyone has tried them on their boat windows. I've also seen a variant of this on the windscreens of aircraft.

Yes, I have a Caframo fan and am really pleased with it. It is very effective at keeping the windows clear of mist with the Wallis. The fan has two speeds, operates quietly and the suction cup mount really sticks to the fiberglass. I highly recommend it. Ron
 
Wow this is my 1st post on your site. I have several of Caframo's products on my boats and find them to be very well engineered and built. They have always performed their task very well. The Sirrco and Kona fans move a lot of air for a small package and low amperage draw. Either combined with their ceramic defroster will keep the front clear on the worst day.

I hope this helps and I've enjoyed your club's site.

My wife and I take delivery of our new 22C on April 6th. Please keep up the good information, it is in large part due to all of your histories with your boats that we bought ours.
 
Welcome to C-Brats to Bob from some fellow Tarheels (to the south, in Hampstead)! For our trip to Key Largo last summer, Cassie and I got an Endless Breeze 12v fan <www.fantasticvent.com> from West Marine. It is 14.75"x13.5"x4.25" and, like most of the fish I catch, weighs less than 5lbs.
We didn't sleep on the boat in Key Largo, but we did at campgrounds and rest stops enroute. We put the fan to exhaust out the center windshield. With the cabin closed otherwise, this sucked a very pleasant breeze in through the hatch. Best Wishes, Bill
