need help please

i have 6" cool tube, two 6" inline fans and 6" ducting, how does it connect?

flanges? do i need to buy them at home depot?

trying to drop the cool tube with 2 fans cooling it. does the exhaust fan need to be right next to the cool tube?

or can both fans be in the ceiling?

minimal space, i have a can fan 33 combo and a 12" wall fan in a 8'x5'8"x2'.

it wouldl help if i could place both inline fans in the ceiling, one drawing in air cooling the tube and one exhausting the hot air out.

need help, thanks.

You connect it by using 6" clamp, they sell them at home depot.
You can have the fans at the ceiling.
Two fans is awesome and should do good. I only have one fan drawing the air in and exhausting.

GOOD LUCK
