Evaporative cooler ducting help.

I have a Master Cool I would like to install on the outside of my attic. I would like to run some flexible ducting in about 25ft. straight shot then a 45 or 90 deg. turn to an outlet in the ceiling. I plan on using updux through out the house as I have a fair amount of attic space I would like to cool a bit also before exhusting to the outside. I am mainly looking for advise on if and what kind of flexible ducting to use as I don't want to risk blowing it apart. The cooler is rated at 6500 cfm.

if I am correct, that is a "commercial" unit 12" pads etc...
I would use 18" or 20" silver flex. 1- collection box - Plenum- Get 2 collars to secure the flex to one at the plenum - 1 at the can and secure the flex to the collars with big zip ties.

THis will do the trick.
