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.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Lab [mailto:lab-bounces@artengine.ca] <b>On Behalf Of </b>j ross<br><b>Sent:</b> 2014.January.22 23:26<br><b>To:</b> lab<br><b>Subject:</b> [Lab] Laser cutter venting<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p>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). <br>Any thoughts or experiences appreciated!<o:p></o:p></p><p>Jeff<o:p></o:p></p></div></body></html>
