Extractor fan for in garage?

[SuzukiGS750EZ]

Hey guys. I converted my garage to a “craft room” for my lady.
She uses laser engravers/cutters and is currently using an undersized fume extractor. It takes up room on the bench top and does a poor job of extraction.
I’d like to run a flame resistant hose from her bench top up through the ceiling, into the attic and out the side of the house.
I don’t work with these materials often if ever so I need some suggestions.
-What could I use as a transition between the ceiling and the attic. A coupler, flange or something similar that would not look so hack and allow me to seal the room from the attic and not allow the hose to fall back into the room or otherwise be pulled?
-What fan would be recommended? When I made the room/attic I did a junction box on either side of the room so I can tap into that for power.
-What hose would be recommended?
Spark arrestor or the like? I can find a vent for the side of the house unless something else is recommended?
Thanks.

What cfm do you need to pull? What size hood are you connecting to? Do you have adequate make-up air? As far as the type of hose to use, I'd look at welding fume extraction hose. https://www.google.com/search?q=wel...GIYDGIAEGIoFqAIAsAIA&sourceid=chrome&ie=UTF-8

Scroll down to duct hose. I'd probably just use flexible hose for the piece near the equipment and go to L or HD and look at metal hose used for stove top vents. Tons of stuff for that use w/ all the adapters and flap vent for the pass through the wall to the outside. BTW a piece through the wall vs through the roof is much, much easier to seal out rain. And they come w/ weighted flaps so they close unless airflow out pushes then open to keep birds and mice out.

I would need 500 CFM or above i believe. So, the hose attaches to the laser engraver itself. The engraver is in an enclosure and the flange for the hose is on the side or back of the laser engraver enclosure. I was wanting to figure out a way to have a dryer vent or similar in the side of the house (in the attic). Hose from that to a fan and then from the fan down through the ceiling and into her work area. She could then couple that hose to the side of the enclosure or with a spring clamp to the hose that comes off the enclosure now.
She is currently using an extractor like you'd use for soldering but made for laser engraving. Now that she's bought a larger engraver the extractor needs to be larger. So my solution was to plumb one up and get the extractor unit off of the benchtop to open up space as well. And venting outside would eliminate the need for filters and cleanup.

I wouldn't mind going through the wall but i figured having a larger fan to push out would require mounting somewhere in the way. The layout of the room is similar to a kitchen with upper and lower cabinets and bench top throughout below the cabinets.

Maybe get a small furnace squirrel cage fan to move the air? Might even find one cheap or free from someone updating their air handling system. I installed the big squirrel cage fan up near the ceiling in my shop to move air around and also to create positive airflow out the overhead door to minimize skeeters finding me in the shop.

1) I would lean towards purchasing a Tough Shed for a She-Shed and sending my spouse into the back yard and out of my man space.

2) If you have to cohabitate, you might consider an exhaust extraction system:


I expect this type of system will meet all the specs you are looking for and when you get your space back, you can put it to productive use on real garage work.

i got a squirrel cage mounted on the wall with some pvc pipe for welding, and a barn fan from tractor supply that can exhaust the whole building in seconds.

Should it be rated for flammable gasses? Not sure of the exact name.
