What might be a good thing for a shop that makes dust might be a cyclonic air filter with a second stage that has the normal type bags on it. I haven't seen one yet, so I might just have to build it. The thing I hate about a lot of dust collectors is that many of them seem to put a lot of the fine dust right back into the room. If you have the collector bags outside, you end up taking your heated / air conditioned air outside. I guess that's why I'm kind of fond of the cyclonic systems. Unfortunately, they're not so easy to find in the sizes a small shop might need. Now, if they could only come up with an air filter to take care of things like the fumes from spraying lacquer, without having to exhaust the air... now there's an idea...
