There are two type of bottom dividers thats the best, but there are some diffrence between us.

Type 1(this is the old version):

Dear Admin, I need your help with something. The measurements on this link for the sketch-up divider are not correct http://sketchup.google.com/3dwarehouse/download?mid=155791f19796bd5370ca523953cfe4ec&rtyp=s7&fn=o-gy+zsoda+vf&ctyp=other&prevstart=0&ts=1263162765000 I also build other types of solar air heaters here is one of them.

There ’s a lot of version of it:
