I know, this is an old story.
I'd like advise on dust collection. Currently I use a single stage dust collector. A 650 CFM Delta unit with a fiber filter bag. It's probably not the best. It's better than nothing. It also fits into available space. I'm using it with a flexible hose connected to one tool at a time.
But I'd like better. Higher CFM. Better fine particulate filtration. Even to centrally locate it and run some ducting to collect from multiple tools, though one at a time. I read that cyclones do a good job, but what about separating out the finest particles? then there's the size issue. Most cyclones are a little too tall for my basement shop. That's key - I work in the basement of my house. This is a hobby, not a business. It's the hobby that got out of control.
I just saw a unit offered by Laguna. Size wise it'd fit, but it's design doesn't look like a clearvue or onieda. Is it any good? Worth considering? Through it all, I'd like whatever to work and fit into the space I have.
