Hello,

I will have a 20' x 25' stall in my new garage that will double as a paint booth. I prefer to have positive pressure venting with a blower on an interior wall blowing in and a vent on the outside wall for exhaust.

Would 1500-2000 cfm would be adequate?

Has anyone bought a blower for this purpose that you are happy with? Where did you get it? How about a shutter type vent for exhaust? I am hoping for something better than the Menards/Home Depot stuff.

Also, what height would be optimal for the fan and exhaust? I would think the fan should be high and the exhaust should be low. They will have to go on the side walls, not the end walls. How far from the end walls should they be?

Thanks!
