Dust Collector Noise

I am looking to purchase a low noise dust collector for my shop. I will need about 1200 cfm at 115/230 volts. Any recommendations?
What is the consensus Delta, Jet or other?
Thanks

I like my Oneida (3 hp) as well though I still put it in a separate room. I have a Delta 850 (1-1/2 hp) as well and the noise factors are roughly the same.
What really amazes me is the noise generated by leaky blast gates.

I like my 1.5hp Oneida too. I got the sound-reducing muffler for mine. It's WAY less annoying than a ShopVac. It's not quiet, but it is non-annoying enough that I often just leave it on for minutes at a time between operations.

Any dust collector is less annoying than a Shop Vac. <G>

a regular bag DC is going to be noisy no matter what. when I turned mine into a cyclone it sure helped. the noise of the dust spinning around in the plastic bag on bottom made a lot of noise.

First of all, the CFM ratings you see on most dust collectors are largely meaningless. What you are looking for is "real world" numbers; i.e., the CFM when you have 6-10" of static pressure resisting the air flow, rather than some measurement taken under very "ideal" conditions. In general, to get 1200 CFM of ***REAL*** air flow at 8-10" of static pressure will require a well-designed 14" impeller spinning at 3450 RPM, and it will take a 3-5 HP motor to spin it properly. A lot of so-called 1000-1300 CFM dust "collectors" have trouble pulling 300 CFM in a real shop, especially if you use 4" hoses. A 10" table saw needs 500-700 CFM under the table and another 300-400 above the table just to properly conduct the dust-laden air to the collector and not to your nose.
If you want a dust collector that WORKS, get a cyclone, but don't trust every "cyclone" on the market. A few of them are well designed, but others aren't. Oneida makes decent units, and woodsucker is OK. RUN (don't walk) from most of the importers. I have a friend who made and installed dust collectors, including cyclones, for years before changing his company into a different product mix. He called an importer on their specs recently and challenged them. His opinion? I better not say because some of these outfits are pretty defensive about the undefensible specs they publish...
For the real scoop on dust collection, go to Bill Pentz's web site for a good education on dust collection [he almost died from wood dust that aggravated existing lung damage from Viet Nam. I have copies of email from others who had a lot of respiratory problems until they installed a well-designed cyclone (one even replaced a major brand-name cyclone with one using Bill's approach, and his lung problems went away)]:
http://cnets.net/~eclectic/woodworking/cyclone/index.html
I have been collaborating with Bill to introduce to the market a top quality, does-what-it's-supposed-to cyclone in kit form. We now have the cyclone unit itself available as a kit, and will have a blower housing in a few days. Other components are available as indicated on his site.
I don't like using newsgroups for advertising, but friends don't let friends buy stuff that can be dangerous to their health, and a lot of these machines distribute fine dust all over the shop instead of trapping it, which is what happens when the collectors use cloth bags as "filters".
Those filter bags pass particles as large as 30 microns, and those fine particles are like tobacco smoke -- they go deep into the lungs where they can do a LOT of mischief, especially nasty stuff like MDF. It's a major problem.
I thought I wanted one of those conventional machines too until I encountered Bill's experiences and realized just how badly I *don't* want one of those. Cyclones are the ONLY way to go if you want to protect your lungs.
If you want to know more, contact me privately by email.
