There have been several discussions at work about these new fangled 'Dark Side' movie killers. All of those that were bought were gotten rid of in quick fashion with little more than a few hours use.

Yeah, both in cost and in loss of suction. That's one thing about even the cheap shop vacs--most of them do suck pretty well because they just let'em rip with no noise damping...

I ran the vac for 15 minutes and sounds fine. I have put it all back together and it's happy now waiting for its next job. Btw..all the electrical data, model number, etc is molded into the plastic motor cover part. I am so sick of the crappy paper and if you're lucky, foil, info stickers they put on everything now. Hell, wash your lawn mower a few times and hope the info plate is still there.

I read a pretty good review on the Fein or is it Fien brand of shop vac, a few years ago. They're supposed to be pretty quiet and work well. They are a little pricey, though.

Surprised no one has mentioned a vacuum powered by your shop air supply:

And I am sure there are plans out there to make something like this too

Glad to hear you saved it.
I bought a Ridgid from HD a few years back it has held up well, I use it to clean up the mill and surface grinder frequently. It has been used to suck up water, antifreeze, and other non-flammable liquids many times. I use it on my glass bead booth with a Hepa filter in it.
I have a Vacuum Material loader motor mounted on a resin drum that will be my dust collector once the shop is finished, it really sucks. I save it from a scrap drum when I work for a local plastic injection molding company.
I have to decide whether to set up two separate pipe systems or build a diverter valve to switch between dry or wet system.
Since I am going to put the system on my surface grinder, bench grinder, and 12" disc sander I need to have a liquid filter to prevent a spark from traveling to the drum. I would prefer not to have the moist air setting in the drum.
Dan.

2 things going on here.....

The fan (or I should say the blower wheel) the blades come around the

I can (and have) laid out these things to have un-even spacing
of the blades, but still maintain balance.

That would take care of the fan noise, but the second part
of the noise is from the brushes riding on the commutator.

Which I can't make the spacing un-even.

I suggest the vacuum manufactures go with a small 3-phase
motor running on a 1-to-3 phase invertor, and over clock
it past 60 hz. for the high speed.

But that would probably cost too much.....
