[Lab] Laser cutter venting

There are fans like "dryer booster" or "in-line duct" fans that
automatically turn on when these detect airflow. You might be also to help
control the flow with dampers...
The simplest seems to vent it through a window. You can make a rectangular
insert out of wood or acrylic and run the vent through that. You could
probably even cut it to size on your laser cutter... :-) you could probably
leave this in throughout most months, and over winter too if you seal and
insulate it well enough.
Gases shouldn't be much of a problem if it is just a wood you are cutting.
But you'll probably want to be more careful with plastic fumes. You should
probably be prepared for the occasional accidental use of wrong material,
like a bit of chlorine venting. From what I've heard, plastics can get mixed
up once and a while so unless you are always buying ones that have the
protective film marked at manufacture, then you may at some point come
across some that was placed into the wrong bin. This usually isn't a problem
as long as you stop the job quickly before the gases corrode the lenses.

You could add one of those "switches" in your dryer vent line. If you mount
it backward, it would prevent the flow from the laser cutter from backing
into the dryer in the "CLOSED" position. In the OPEN position, the dryer
would vent outside and no into the laser cutter.
BTW, I'm NOT advocating the use of such a switch as advertised, unless you
want a mildew problem in your home!
