[Lab] Laser cutter venting

[Janick Bergeron]

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!
