Well my HOA is harassing me again about exhausting the laser out the window. I’m fed up and am looking at getting a fume extractor and was wondering if anyone in the community has any experience with the professional grade ones?
I found in another forum post that the Glowforge people are using a BOFA extractor at shows. Anyone know which one? @dan@Rita
The room does get somewhat smoky as a result but quickly clears as the ( I call it the blue whale as it is big, blue, and a filter-feeder) can move 500-CFM when on full . It is somewhat loud but a low white noise, less so than the shop vac that is also whiney,
They sell 10-inch to 4-inch adapters but they take up almost as much room as the Whale, so I have not yet gone that way but your situation may be different. Even if at some future time I should get the Glowforge filter I ordered I will still use the Blue whale as it also clears out all the smells and dust that sanding and other operations create in abundance.
Have you seen this thread? I came across it while doing a search recently. There is something called a “Fume Coffin” that you can build for around $350. I may give this a try, because even with venting I am still getting some odors.
Surprised they haven’t gone after you for having a home based business–many HOAs prohibit that, too… that may be next on their list of actions! Good luck getting off of, and staying off their radar…
Maybe you can add a “dryer vent”? It’s not the window, just a small hole in the wall & nice looking vent covers exist… If the HOA doesn’t prohibit that, may be worth a try (though likely once they figure out what you’re doing they would change the bylaws again)…
I decided to buy a BOFA 350 so I don’t need to exhaust out the window anymore. I heard that’s the model that the Glowforge folks use at conferences. @dan@Rita can you confirm and/or share any thoughts?
Airflow/pressure: 223 cfm / 96 mbar that is a very low airflow, and could be a problem as I have a 199cfm that I thought would do but is quite insufficient when cutting smoky things like oak plywood or most 1/4 inch thick woods.
