Quiet 12v Galley Blower?

My point is that it gets loud because the bushings wear quickly, and that is the cause of the increased noise in many cases. Yes the fan still moves air for a long time after the bushings get noisy - it just isn't tolerable. That is what happened with my Hella fans.

It is quite possible to find, or at least make with a 3D printer, adapters that attach to computer fans and provide a tube for the duct hose to slide over. As I noted before, fans are available in a broad range of capacities. Just going to Frys and buying one is not likely to yield an adequate fan - look around on the internet and order the most powerful one and I think you may find it will serve. Still, probably not the airflow of a bilge blower but not the noise either.
