Fume Hood Venting Idea
Okay-
I am pretty young- 15 years old. So I still live with my mom and dad. The only place I can set up a lab is in the basement. I have been working on an
idea for a fume hood for a LONG time now- and I am near the climax.
So... a couple days I went to Sears outlet and got a nice range hood that was scratched for $40. I put on an expensive duct costing $10 more. I am
making the hood box out of shelving material for it's flame and chem resistence. I also bought various dryer ducting supplies (I know aluminum isn't
corrosion resistant, but when air is moving thru a 4" diameter tube 10' long at 160 cfm, I don't thing it would do much damage.). The shelf and
ducting supply was $70. So far I am almost at my $150 budget. My dad can get me lexan for nearly no cost... this is gunna be one epic hood! One
issue... Because it's my parents house I don't want to destroy it by putting in a dryer vent and cutting a hole in the house. So- I have a small
window above my lab like this:
So- My thinking is take this big aluminum spring powered badass vent and ghetto mod it into the window where it opens. Prolly something Primo Levi
would've done. I am just having a bit of trouble thinking of a way to seal it to the window... Any ideas?

Where is the window facing? Ultimately your fume hood may not be a wise idea on the basis that it will then be pushing fumes out into the front yard,
or up along the side of your house - which would be altogether horrendous for anyone caught in the way of what you are venting.

Careful venting flammable solvent fumes through those. The electronics are not isolated and a flash fire is a real possibility. Many home fume-hood
designers spend great effort to house any source of ignition out of any path that the fumes may take. Check out the thread here on homemade fume-hood
design. I once had a flash fire while distilling a solvent because I was using an inline-duct fan to vent the process. Very scary. Whoosh!
U.T.F.S.E. and learn the joys of autodidacticism!
Don't judge each day only by the harvest you reap, but also by the seeds you sow.

The window leads to my back yard- no one has access to it, the house is made of brick, and no windows are above it. This will work... Oh, and, I
should mention- I never use quantities over 100mL with dangerous solvents and I try to keep them colder... For the wiring to ignite a gas would be
really... really... rare in my design and purpose.

Glad to hear you are near a climax.
You have to remove the existing louver window, then install a duct into the window. The duct can be sealed with caulking. Remember that there should
be some way to close off the window when the vent is not in use. This can either be via a removable panel that goes on the outside of the window or by
installing a seal-tight damper in the ducting.
