MY QUESTION IS WILL THIS FAN GET THE JOB DONE?

Absolutely.

im gonna have 6" wide ducting running into my attic from the top of my box (aprox 8 ft. of ducting) put that fan placed in the top of the box with like less then a foot of duct to the cool tube..... when smell begins to become an issue im going to run some duct, bout a foot, have a 6" to 4" duct adapter connected to the 4" carbon filter.

will that work or do i need to get a 6" carbon filter

i would do it all 6", or all 4"

i have 2 valueline 6" and they are working great! Little bit loud, but cheep!
