One way to make them more quiet is to mount them far away from the galley, and use as low RPM and large blade fan as possible. Smaller size means smaller blades means more RPM for the same volume of circulation, equals more noise. Don't forget also that there will be noise in the ducting proportional to the speed of the air in there, so you want the largest duct you can manage.

Our galley exhaust blower is in the lazarette with the engine room blowers, and sucks through a long large diameter duct, and it's not too noisy. It exhausts out the transom together with the engine room blowers.

I realize this exact set up is not an option with a cat, but maybe there is some way you can route the duct to get the blower away from your space.

Whatever you do, feel lucky you have one at all This device is not all that common in my experience, and is worth its weight in gold, even if it's noisy

+1.

It almost seems embarrassing to admit to having a range hood and exhaust, but I don't ever want another boat without one. It is amazing how all the galley heat simply goes out the vent, not to mention all the steam and such.

The biggest downside is all those moochers anchored downwind whenever bacon is frying or bread is baking. It's like setting up one of those CO2 traps for mosquitos….

Indeed And remember, unlike at home, we're cooking with propane. The main combustion product is -- water, and lots of it. That needs to be gotten out of the house in the most direct way possible . . .

I sure remember the misery of all that water vapor on previous boats without galley exhaust blowers. . .

I got this mental image of cooking dinner in a mooring field with all these scruffy looking red-eyed miscreants zig zagging back and forth in old patched up RIBs with their noses in the air like a pack of Labrador Retrievers working their way upwind to the duck....

Re: Quiet 12v Galley Blower?

Just today received a Rule exhaust fan, and I also bought a 12 volt fan control circuit. The sound level is much, much less than the one I was complaining about. Thanks for the info, Mark.

Mark? Hello, Mark? chirp. chirp....
