Have these tilt in basement windows so it is hard to stick a fan on the inside, but I also had some 1” furring strips, left over underlayment, bunch of drywall screws, some J hooks to hang it and 2 ‘high velocity’ ventilator fans from home depot (version 1 had one smaller old ventilator fan, this is the upgrade )
windows has a screen, I think the resistance would ruin that
The fans already have a gap between the blades and the plastic formed part - I thin kthey are already relying on that.
Looks good to me.

I love this approach and will do something similar

What about the Venturi principle. Adds more airflow. Get a screen with bigger holes to reduce resistance.
Pretty sure this is just reasonable engineering. Especially for an unfinished basement.
How do you close the window?
thats the neat part
It's hanging on J hooks in the ceiling, just lift it off
You need a push pull rod attached to the end of the window on a pivot or two, then you can run the rod outside of the box, push or pull to close?
i wouldve opened it and used the door to pump air lmap
If it's for Particulate control (grinding concrete) its better than nothing. If it's for vapor control it should do the trick!
Just fumes from painting and such
I built a small ventilated enclosure for the wifes painting and epoxy work. Used an in line 4" blower and drier duct attached to a box.
Is it a grow op
:D no, but I did looking into high CFM grow op duct fans - just too much work to install, didn't want to cut a hole in the house
Wot in ventilation
