Hello all,<div><br></div><div>I'm Andrew, an undergrad Mechanical Engineering student at Carleton. I'm new and haven't visited the lab yet. A few ideas and comments after a few summers of HVAC installation.</div>
<div><br></div><div>- I picked an 8" inline fan during the Glebe garage sale. ~$350MSRP for $20 used, ~580 cubic feet per minute. Elicent AXC 200B Data sheet here: <a href="http://www.elicent.it/upload/allegatiprodotti/axc.DYN4eb29f21cc79e.pdf" target="_blank">http://www.elicent.it/upload/allegatiprodotti/axc.DYN4eb29f21cc79e.pdf</a></div>
<div>- Most fan types will work for venting the laser. Shorter duct runs, with higher radius turns are preferred.</div><div>- Use aluminum foil tape to seal the joints (surfaces need to be fairly clean), available at hardware stores. Duct tape disintegrates after a few months. Alternately a more permanent seal can be created with duct sealer, (borrow from an HVAC guy, see <a href="http://www.ductmate.com/product.aspx?id=23" target="_blank">http://www.ductmate.com/product.aspx?id=23</a>).<br clear="all">
<div><div><br></div><div>I can help build a hood if the laser doesn't have a build in air collection system.</div><div><br></div><div>Sincerely,</div><div>Andrew Post</div><div>Mechanical Engineering Student</div><div>
