Neighbor Noise
Carol,
Somewhere in these threads, Jameel Abraham provided an audio file of his cyclone running, and for comparison, his table saw as well. Jameel built an insulated closet, and the audio is with his door open and shut. That'll give you some idea of the sort of sound these things make. If you look in the member list, then for his name under the "J"s, you can find his posts. If you have trouble finding it, holler and I'll give it a go.
Mine's still under construction, but I have started it and let it run a few minutes, without ducting and with the bottom of the filters open. It was not as obnoxious as I'd feared after reading the posts. My old dust collector (dust pump, per Bill Pentz, and rightly so) is a 1 HP Delta 2 stage. The CV1800 is perhaps a bit louder, but similar in frequencies, more a rumble than a shriek. There is a fair amount of hiss from air going through the filters. Again, you can tell its there but its not as dominating as first feared.
The fan unit is very smooth running. Matt does a good job balancing his fans. So, sure, putting some sort of vibration pad under the mount is quick and easy if you plan for it ahead of time. Which sort of makes any discussion about whether or not its necessary moot. Slap it up there and forget about it.
I think the "take away" from the above is that you might want to make space and other planning provisions for some noise insulation, but get the thing running then go see if you actually have to do it. Could be your attic provides sufficient noise absorption or deflection characteristics so the neighbors barely notice it.
The metal bits on the CV1800 (not including the filters) are the Leeson motor, which is painted, and the impeller, which is powder coated. Certainly some paint gets knocked off the Leeson and its mount flanges during shipping, but that's probably insignificant. My impeller arrived with only slight witness abrasions to the powder coat, none through the coat to the metal that I could see. Other than the fasteners (bolts, screws, T-nuts), all else is either PTEG plastic or MDF. So I don't think rust will be an issue for you there.
The filter flanges (if you get Wynn's) are probably the most likely to show rust first. These are industrial style filters, designed, I think, to be replaced with some regularity and/or sit in some sort of housing. So the paint on the flanges is there primarily for looks, not protection. And it does get scratched and chipped in shipping. We're not using them that way, and expect them to last longer. So in your (and my) environs, I think those will be the first to get rusty. But I don't expect to live long enough to see that day. If it bothers you, you can always tape off filters and spray the flanges with some Rustoleum.
Regards,
DWD
