What do you use for dust and fume extraction at your sanding and finishing workbench? I purchased an inexpensice fume hood fan and that would not work well unless it was inside an enclsore. I returned that and bought a Penn State dust collector head and that may be overkill. Perhaps a squirell cage fan would work? Just looking for ideas on the "fan" and any ideas on how you implemented the bench used for sanding and finishing.
Dust and Fume Extraction

For me, dust and fume extraction are two different problems.
I use a Ridgid shop vac connected to a Dust Deputy dust collector. A longer hose goes from the Dust Deputy to my spindle where I mounted a custom connector. The Dust Deputy does a great job of capturing dust and wood chips, dropping them into a 5-gallon bucket. The remaing air is pulled into the Shop Vac where I installed a HEPA filter to get the fines.
Fume extraction is handled by a separate exhaust fan that goes directly outside through a wall.

I agree with Gary. Fumes and dust need different solutions. For dust, a dust extractor or downdraft type system connected to a shop vac works well.
For fumes from epoxy, and especially clear coat, you need a different system all together. A fume hood, spray cabinet or a separate room is needed. You need a way to suck the fumes out and vent it out from the area you're working in, so you need and explosion safe fan with enough power. A 3 stage filter that delivers breathable air, so you can use a fresh air mask while spraying or working with chemicals is key. You can get by with a 3M full face mask with the right filters if this is something you do very seldom.

I use this in a downdraft box under my spray station and toss the hose out of the shop door. Works pretty good

I agree with Kim and Gary, it's two different processes. You don't necessarily want sanding dust where you're doing your finishing. I got tired of wearing a mask while sanding so I took a couple hours and some scrap and built this downdraft box. It has dovetail rails on the bottom so it just slides over the ways. I hook it up to my dust collector while sanding and problem solved. It also gives some protection to the lathe bed. I'm still working on perfecting my finish area. I'll probably go with something similar to what cuemaker supply mentioned above, but I'd feel more comfortable with an explosion proof fan.
