Hakko makes a good fume trap and if you have a way to vent the air
outside you could juririg a stove top exhaust. It's the fumes from
the flux that you need to vent away not from grinding unless you are
grinding dry.


Thanks, I'm looking up their info

((I'm trying to decide whether I should go for a fume hood or fume
collector, or whether I could get away with turning my Miele on and
wiring the nozzle to the desk (it has a HEPA filter and I can get
either super- filter bags, or HEPA bags for "double filtering"), or
whether I should get a window fan (pointed outdoors) and rig up a
duct. Or maybe just get a small folding table and chair and do it
outside before the day heats up too much ))

One thing to consider is that HEPA stands for (more or less) "High
Efficiency Particulate Air" filter. The key word here is
"particulate". Although they are very good at trapping very tiny
particles, there is a lot of non-particulate stuff (fumes) that are
released during soldering. HEPA won't do squat about those.

Like Chemo noted, you need a fume trap (does Hakko make one big enough
for sg work? I only know of their electronics stations). A homemade
fume hood using a stove hood and venting *outside* would be much
better than any filtration system. Just extend the sides of the hood
down further towards your bench.

Of course, there are advantages for good air filtering as well, but
ridding a shop of fumes ain't one of them.

Oh, OK - so the main thing is venting to the outside. My desk (I'm just
starting out) is right in front of a douple window, so maybe I should rig
up a vent (rather than leaving the whole window open to the Houston
heat'n'humidity ) that'd funnel air the 18" or so from the desk to the
window, maybe put a particualte filter up-front so the fan doesn't get
all clogged up.

I can't go too expensive so, if it seems like I'm lookng for inexpensive
solutions, it's becasue I am G! At the same time, I don't want to
ignore safety. So far, I'm doing granding and soldering outdoors, but
it's a bit warm right now ((I'd looked at a few soldering-station
units, but all they seem to have is a charcoal filter, so I didn't get
any of those.))

Thanks for the info! -
