I think I read every post in this forum. Been scouring crags list for a "real" fan or fans with no luck. Seems to be a weird break where you can buy box fans for just about nothing, while real fans are $100s if not a $1000 dollars.
Pretty clear to me that real HP is needed and box fans don't have that. I have seen some flow rating on box fans and it's in the 2000 to 3000 cu. ft/min range, but based on the low cost and of course low HP, that must be against no static pressure and I'm sure with any pressure against them the flow drops dramatically.
I have hanging around my place 5 box fans. My plan is to make a plastic sheet wall to cut my garage in two, line the 5 box fans on this plastic wall blowing in through filters, and leave the 3 windows open on the far wall. I'm thinking that 5 of these fans on high should move enough air through the filters and out the windows. Not as much as a real booth, but hopefully enough that the fog doesn't lay back on the top.
Is the consensus that that might work? Or do I need even more box fans, or do I punt and keep scouring craig's list?
Edit: And how sophisticated do I need to get on the filters? Do I get really boot filters from the local jobber, or would something like this work? http://www.homedepot.com/p/Rheem-20...old-Pleated-Air-Filter-64100-012024/203140810
