Fan question

[jasonandres]

Here is a fan question for you guys. I'm building an oven roughly 4' by 4' by 8' long, it'll be laying down on the 8' side. I'm putting 3 elements inside on the floor evenly spaced. I know that I need to circulate the air from the top to the bottom; but do I need more than one fan? I was thinking that if I put the fan in the middle and recirculated to the bottom that the upper corners would'nt benefit and I'd have hot spots. Maybe I'd need a fan over each element? Thanks for any replies.

you don't need multiple fans. run a duct from the top two corners to a wye (or tee) at the blower intake, add a wye at the blower exhaust, and run your ducts to the lower two corners.
