    Default Ventilator/Extractor fan

    we've got a normal "pancake" Ventalite thingy above our heads compartment. We'd like to fit some form of extraction in there; I've got a nagging feeling that I've seen a combination flattish vent/extract unit somewhere.

    Any recommendations?

    thanks

    Do you mean a UFO vent? I think some are solar powered!

    There is, or at least was, a solar fan kit to fit the Tannoy Ventilite and similar ventilators but solar powered ventilators did not get particularly favourable response when discussed on here some while back. I know the Ventilite and I wonder if it would be possible to fit a small 12 volt fan in one. There are a variety of such fans availble from electronics component suppliers eg Maplin or of course from old computers!

    Attach the fan from an old computer power supply underneath the vent. Very low power consumption, very effective, very cheap.

    One thing I discovered is the insect screen within the vent can be come clogged up with dust that turns grren and grows algae thus stopping any ventilation whatsoever. Worth

    those solar vents have a habit of breaking the day after the warranty has elapsed. Fit a computer fan in there instead and the current draw will be minor, but the ventilation effect will be much better.

    there seem to be 'expensive' and 'cheap(er)' solar powered vents. Anybody know if the more pricy ones are better? The concept (no wires, looks better, permanent) looks too good to ignore if they actually work.

    You need lots of air movement in enclosed toilets, I doubt a computer fan will do much at all.

    The best system I ever saw was an in-line fan installed in the dan-buoy tube that was extended from the stern to the toiled (located to port near the companionway)

    Another had an in-line fan that vented to the anchor locker, not as good as the dan-buoy tube but a lot better than the fixed vent on deck.

    Look for a high volume air flow or you may be wasting time and effort.

    [/ QUOTE ] I came to the same conclusion. I fitted a bilge blower in the heads cupboard, venting via a duct to the chain locker. It's controlled by a push-button connected to an electronic timer which lets it run for about 5 minutes and then switches it off. Works a treat!
