I have been trying to improve the ventilation in my spray booth for awhile. My spray booth is 12'x12' plastic, cardboard and craft paper on the floor and 6 mil walls. It is in the basement and has an egress window in the wall of the spray booth that I use for exhaust.
I have been using a variety of household and "industrial " fans with less than perfect results. I have been doing a lot of shop upgrades lately so the thought of spending a bunch of money on an exhaust fan that may or may not drastically improve the ventilation.
I found this wall fan designed for greenhouse ventilation

It runs $70 and moves around 1000cfm. I set it up today and it works absolutely great!! I would have been happy with the results even if i had paid twice as much.
Thanks
