As far as fume extraction for your shop. A more affordable method is
to install Fantech (or similar) in-line fans in duct work that is
vented outside. They move a lot of air, are compact, and run quietly.
Then run progressively smaller duct down to you bench, solder
stations, etc. You can then use aluminum dryer vent attached to a 4"
duct to place the inlet where it’s needed. For your kilns you need a
hood, usually 2’x2’x 18"deep for a standard single kiln. If it’s a
one or two person shop with 3-4 stations you can do it with one fan
and for less than $1000 even if you pay a HVAC guy to do it (they can
better calculate you cfm needs and then size the fan you need).
We use a chemical fume box for our plating fume ventilation. It’s
2’x2’x2’ and is made out of tempered glass with a chemically
resistant base, the back is slotted and then vented out the top.
These are fairly costly to buy but not hard to build if one is so
A nicer looking and still less expensive option (but more than a
than the dryer vent) for a fume arm is to buy only the fume arm from
the Quatro Solderpure fume extracting station. That will cost you
about $90 with the blast gate. The bigger fancier fume arms can get
very expensive, $600 and up, but don’t always work better.
