[Lab] Laser cutter venting

It is best to vent lasers with the fan at the outside, to keep the pressure
in the duct lower than outside to ensure the fumes don't leak into the room.
If you do it this way, using the same hole for the dryer would work fine:
make sure the fan is after the joint. You'll also have to turn this fan on
for the dryer.

Subject: [Lab] Laser cutter venting


Just received my new laser cutter so next step is to setup the venting. Was
thinking of doing a T or Y connection to the dryer vent but worried about
some exhaust coming back into the dryer. Would like to avoid punching
another hole in the outside wall just for the laser. Could hijack a basement
window if needed. Hepa filter unit is possible but a last resort (drawing
from the Modlab experience and cost). 
Any thoughts or experiences appreciated!
