Re: 12v Fans......?

I've got a few Hella Fans. They are quiet, adjustable (speed and direction) and move decent air.

+1 on the Scirocco fans.....I replaced an older Bora with a Scirocco recently and it is much quieter, moves more air at high volume, and has good adjustment from high to low. Plus there is a staged timer built-in, so I can leave it on for some background noise and breeze as I fall asleep and it will turn itself off after an hour or so.

Re: 12v Fans......?

Caframo is tops. And the 747 model moves more air per milliamp than any other model I've found. 400 milliamps per fan on high speed and 200 on low (but who uses low speed?). And they move more air than Scirocco or any other model. West Marine stores sometimes have a display that allows you to test the various 12V fans they sell. I ran them all and the 747 was clearly the best. One problem with them is that the suction cup provided with the fan is useless and won't stick on any surface in the boat. However when I emailed them they sent me three suction cups from older models that did work. Said they were working on a solution. West Marine sells clips that fit the fans if that is a reasonable method of making the fans portable on your boat. The fans also come with mounts for permanently mounting them that are good mounts.

The 747 is also a quiet fan.

Re: 12v Fans......?

In my local Fry's electronics they had a nice selecton of 12v computer fans that were composite and cheap! like $12. My next fan is gonna be something easily replaceable and a home-made mount.

Re: 12v Fans......?

Thanks for the inputs, seems that having to go with the higher cost "marine" option just pays off. Looking at other fans at 1/3 the price it seems you just get a mixed bag of fans made in china with noise, reliability levels all over the map.

Re: 12v Fans......?

Just came across an interesting article on balancing fan blades with a strobe light. Looks like another boat project.

Apparently I don't have enough posts to leave the link so just google:

Re: 12v Fans......?

I have 3 Caframo Sirocco Fans. They are quiet energy efficient and move a ton of air/

They also get an incredible amount of dust on them.

Re: 12v Fans......?

Yet another vote for Caframo. I have 4 of the two speed compacts. On slow they are quiet enough to use while you are sleeping.

Worth carrying spare blades as they do fail sometimes.
