Hello all,
Does anyone know where to get an exhaust fan with charcoal filters?? I try to glass my boards at night, since I don’t want the neighborhood going crazy, but I’m looking for something that will take the smell out of my shack, but not throughout the neighborhood
Thanks,
Tom
Hey TS,
you could try these,

but def have to build a plenum box so you can use between 4-8 filters at once dep on fan speed.
Plenum: just a large plywood/particleboard box like 4’x6’x2’ that your fan blow into to create pressure
and the filter elements are mounted opposite, into an “exhaust wall”.
Better yet, have the filters on the intake side of the plenum and the fan outside, this protects the
fan (but may gum up your filters) (You could always change them to reg A/C filters when sanding).
If you have the time and $, you can pre-filter with reg A/C panels and have the Charcoal panels after
that- so the more expensive charcoal panels live longer.
You can get a decent fan at a home improvement store. Figure on about 20" powerful type, industrial
rather than a house box fan. I’ll try to get some pics if you like…
Hope this helps,
George
Thanks for the info that sounds great. If you could post some pics that would be great too.
Thanks
If you use epoxy with no additive F, there is hardly any smell. Just a thought.
Ima noob ymmv
There’s a nice tradewind flow right thru my tiny shed. I been glassing my shortboards during weekday mornings with UV cure-
-sun is strong
-my neighbors are all at work/school
-10 minutes in the sun it’s cured, ready to flip or sand.
-without catalyst the odor is much less
-the liquid resin smell is gone once it’s hard
Hey Tom,
I got those pics, taken in a dark room. This place was for shaping and sanding boards.
Glassing would be a bit different in set-up. Good points about epoxy and UV which both
reduce your hazards too. Ventilation is definitely worth considering as a serious topic.
The picture below is a 20 inch floor fan modified to fit into a “false wall”. Notice there
is a seal all around the fan cage, which was made from pipe insulation:
The fan blows air away from your view, out the wall. Power cord plugs into standard wall
outlet. The piping stand was discarded and some flat strap metal was affixed to the sides
of the hole in the wall. The fan cage was connected from its mounting bolts to the metal
straps on either side of the hole. Here is a close-up of the mount, if it makes any sense:
It’s covered in dust residue mostly from sanding but also shaping. I’m told the room stays
cool on hot days without any A/C. On cold days, you just gotta bundle up like we do in
vented factory places…
Hope this is useful,
George
Thanks for all the great info… I glassed a board today wearing a full on protected mask with filters. Am i I still going to be smell hazardous smells. I get a smell of the resin, but isn’t all the harmfull toxins filtered out???
if you can smell anything, it probably doesn’t fit you right…or the filters are bad.
