Last week, three people came from Ace Monster Toys (sent by Heph) and said that the ventilation is not a problem at where it is located and is good. I forget the three peoples' names, but feel free to ask Heph for them. <div>

The Full Spectrum laser has a vent fan, which is sufficient when the<br>
exhaust hole vent is located 4-5 feet away from the laser cutter.<br>
If we are going to continue using the roof to vent the laser, we will<br>
need a blower capable of ~650 cfm while maintaining 4 inches of static<br>
pressure. It's a fairly high-flow blower, but inexpensively sourced<br>
in a number of places.<br>
<br>
(e.g. <a href="http://www.globalindustrial.com/g/hvac/exhaust-fans/in-line-duct-fans/in-line-range-hood-exhaust-fans" target="_blank">http://www.globalindustrial.com/g/hvac/exhaust-fans/in-line-duct-fans/in-line-range-hood-exhaust-fans</a><br>
)<br>
<br>
If we move the laser to the table next to the window, and find a way<br>
to build a vent on a window (4-5 feet away) we could just continue<br>
using the built-in fan.<br>
